Title: System and method of stabilizing soil

Description:
FIELD OF INVENTION 
     The present disclosure relates to a filed of injecting a composition into soil. More specifically, the present disclosure relates to an arrangement and a method of injecting a composition into an expandable element in the soil. 
     BACKGROUND 
     As known, earth is the structural foundation support for houses, buildings and other structures. It is well know that strength and support of the surface of the earth changes due to geological changes. As a result, the structures that may have been built on a solid surface, may at a later date become instable, which can lead to severe property damage or even the collapse of structures that have been build there. 
     There could be various reasons that cause soil instability. For example, the soil instability may be caused by an earthquake, poorly consolidated soil, water-induced erosion, inappropriate soil type during construction, or variations in temperature or humidity conditions. In addition, the soil instability may be caused by changes in conditions due to mechanical damage, such as breakage of water or sewer pipes. 
     In order to improve the foundational support strength and characteristics of soils, civil engineers are using modern construction practices. In other words, the civil engineers are using modern construction practices to improve soil and/or lifting the structures. In order to improve the soil and to lift the structures, one such solution provided includes injecting a material into soil that expands as a consequence of a chemical reaction. Injection typically requires drilling a hole in the ground. After the hole is made, the material is injected into the hole under high pressure. An amount of the material to be injected may be determined by examining the properties of the soil. The sufficiency of the material to be injected is checked by periodically measuring the properties of the soil. However, such a process for determining the amount of the material to be injected is slow and unreliable. Further, the material used to inject into the soil is does not provide the required strength to support the structural load. Also, currently compositions used to expand react too quickly and many times solidify before making their way to the required location in the soil. 
     SUMMARY 
     The above-mentioned unsolved problems are addressed by providing an arrangement and a method of injecting a material, which expands as a consequence of an efficient chemical reaction into the soil. 
     In one aspect of the present disclosure, a method of improving soil condition and/or lifting a structure is disclosed. At first, a first hole is drilled in soil. Subsequently, a first pipe having a cap positioned in its bottom distal end is inserted into a first hole. Further, in proximity to the first hole, a second hole is drilled. Further, sensors, e.g., a first sensor and a second sensor are inserted into the second hole. The first sensor and second sensor are used to collect information of the soil in real-time. In the first pipe, a filler tube is inserted into the expandable element. Further, the expandable element is inserted into the first pipe. The filler tube allows a composition to be injected therein and then into the expandable element at a controlled depth. Subsequently, the first pipe is retracted from the first hole. After retracting the first pipe, the expandable element remains in the first hole and the cap remains buried in the soil since it is removably mounted to the first pipe. Subsequently, a composition is filled under pressure using the filler tube into the expandable element. The filler tube in the first pipe is lifted to allow the composition to flow out of it and into the expansion element. This pressure of the composition pushed into the expansion element is what causes it to expand. The rate of lifting of the filler tube is determined by pressure used to pump the composition, by the specifications for a particular job site, or by the chemical reaction detected by the first sensor and or second sensor. When the composition expands 3% or less it is referred to as permeating while an expansion greater than 3% is referred to as expandable. Expansion element  110  is always expanded when filled by the composition  114 . If expansion element is not expanded it typically means that the pump that fills it with composition  114  is not working properly or the soil is too hard. 
     In another aspect of the present disclosure, an additional hole i.e., a third hole is drilled in proximity to the first hole. In the current aspect, the first sensor is inserted into the second hole and a second sensor is inserted into the third hole to increase the precision of the system. 
     In yet another aspect of the present disclosure, the second pipe, comprising hoses is inserted into the first pipe to inject the composition into the soil. 
     The features and advantages described in this summary and in the following detailed description are not all-inclusive, and particularly, many additional features and advantages will be apparent to one of ordinary skill in the relevant art, in view of the drawings, and specification thereof. Moreover, it should be noted that the language used in the specification has been principally selected for readability and instructional purposes, and may not have been selected to delineate or circumscribe the inventive subject matter.

     DETAILED DESCRIPTION 
     In the present disclosure, relational terms such as first and second, and the like, may be used to distinguish one entity from the other, without necessarily implying any actual relationship or order between such entities. The following detailed description is intended to provide example implementations to one of ordinary skill in the art, and is not intended to limit the invention to the explicit disclosure, as one or ordinary skill in the art will understand that variations can be substituted that are within the scope of the invention as described. 
     The present disclosure discloses a system and a method of improving soil condition and/or lifting a structure. In one example, a first hole is drilled in soil. After drilling the first hole, a first pipe having a cap is inserted into the soil. Further, in proximity to the first hole, a second hole is drilled. Further, at least one sensor, e.g., a first sensor and a second sensor are inserted into the second hole. The first sensor and second sensor are used to collect information about the soil. Further, a filler tube  112  is housed within the expansion element  110  that is inserted into first pipe  106 . The filler tube allows a composition to be injected into the expandable element at a controlled depth. Subsequently, the first pipe is retracted from the first hole. After retracting the first pipe, the expandable element remains in the first hole and the cap is separated from the first pipe. Subsequently, a composition is pushed under pressure using the filler tube into the expandable element. The filler tube is then lifted while filing the composition is released into the expansion element. The rate of lifting of the filler tube is determined by pressure of the composition or by the chemical reaction detected by the first sensor and or second sensor or by an engineer. This process can be repeated in the non-encapsulated embodiment wherein the composition  114  is injected directly into the soil. The material injected into the ground improves the soil beneath a structure, such as a house, by creating a resistance once the material permeates the soil, solidifies the soil directly or expands and solidifies the soil. In one embodiment, composition  114  may not expand, or expand 3% or less, upon getting into contact with its other components and/or the soil. In another embodiment, composition  114  may expand more than 3% upon getting into contact with its other components and/or the soil. The various embodiments for improving soil condition and/or lifting a structure are explained in conjunction with the description of  FIGS. 1-5 , further described below using numerals to identify components in the system and its alternate embodiments. 
     Referring to  FIG. 1 , a system for improving soil condition and or lifting a structure is shown, in accordance with one embodiment of the present disclosure known as encapsulated. The term encapsulated refers to composition  114  being used within expandable element  110 . The term non-encapsulated refers to composition  114  being injected into the soil without the use of expandable element  110 . At first, a first hole  102  is drilled in soil  104 . In one implementation, the first hole  102  may be drilled through a foundation of a structure such as a house or next to the foundation. The first hole  102  may be drilled using a hydraulic system, air system, power system, water pump and so on depending upon condition of the soil and the depth required. In one example, the first hole  102  may be drilled at an angle of 90 degrees with respect to the surface of the ground. In another example, the first hole  102  may be drilled at an acute angle from the surface of the ground. After drilling the first hole  102 , a first pipe  106  is inserted into the first hole  102 . The first pipe  106  is terminated on the bottom distal end by a cap  108 . In the first pipe  106 , an expandable element  110  is inserted. In one example, the expandable element  110  may be made up of a permeable or resin material. Further, the expandable element  110  comprises a filler tube  112 . In other words, the filler tube  112  is inserted into the expandable element  110 . The filler tube  112  is used to deliver a composition  114  into the expandable element  110 . The expandable element or otherwise known as the expansion element  110  can be made of a polyurethane, fiber or rubber. Expansion element  110  can be permeable or impermeable. 
     Subsequently, the first pipe  106  is retracted from the first hole  102  such that the expandable element  110  remains in the first hole  102 , and the cap  108  remains in place at the bottom of the expandable element  110 . In one embodiment first pipe  106  can be flexible. When composition  114  uses expansion element  110  the sensors will monitor the composition&#39;s reaction and the expansion of the expansion element. When composition  114  is added directly into the soil without the use of expansion element  110  the sensors are used to monitor the migration of composition  114 . 
     Further, in proximity to the first hole  102 , a second hole  116  is drilled. In one example, the second hole  116  is drilled in parallel to the first hole  102 . The second hole  116  may be drilled using a hydraulic system, air system, power system, water pump and so on depending upon condition of the soil and the depth required. After drilling the second hole  116 , a second pipe  118  is inserted into the second hole  116 . The second pipe  118  at one end or proximity to the end may comprise at least one sensor. In one example, the second pipe  118  may comprise two or more sensors. For example, the second pipe  118  may comprise a first sensor  120  and a second sensor  122 . In one example, the first sensor  120  may be a camera. Specifically, the first sensor  120  may be a borehole camera. In one example, the second sensor  122  may be a level sensor. Specifically, the second sensor  122  may comprise a theodolite. The functioning of the various components mentioned herein is explained in the following description. Sensors  120  and  122  can be lowered and raised within first or second hole  102 ;  116  to better monitor the reaction of composition  114  or migration of said composition and/or expansion of expansion element  110 . 
     In operation of one embodiment, the composition  114  (stored in a container) is pumped in units, gallons, pounds, strut, or cubic yards through the filler tube  112  into the expandable element  110 . In one example, the composition  114  is a an epoxy/resin mixture. The terms epoxy and resin are used interchangeably and will be referred to as the epoxy/resin mixture. The epoxy/resin mixture can be single component or two component. Two components includes Resin component A and Resin component B that can react when combined. In another example, the composition  114  comprises an epoxy/resin mixture and grout, such as a cement grout. In another example, the composition  114  comprises an epoxy/resin mixture and sand. In another example, the composition  114  comprises an epoxy/resin mixture and any type of soil. The composition  114  used is based on the condition of the soil. When the composition  114  is pumped under pressure, the composition  114  begins to expand the expandable element  110 , as the filler tube  112  is raised. Due to fill and the pressure, the expandable element  110  expands. Further, the composition  114  when used as two component reacts when Resin component A and B react and solidifies in the expandable element. In one implementation, the expandable element  110  used may expand using the above mentioned fill pressure and the composition  114  may expand only up to 3% within expandable element  110 . In another implementation, the expandable element  110  used may expand using the above mentioned fill pressure and the composition  114  may expand more than 3% of its original dimension within expansion element  110  The amount of reaction needed depends on the soil. In one example, the composition  114  includes at least one of resin, polyurethanes, or combination, thereof may be heated before being pumped through filler tube  112 . The composition  114  may be heated depending upon the type of the combination used in the composition. 
     When the composition  114  is being released to fill the expandable element  110 , the first sensor  120  monitors the amount of the fill and the second sensor  122  monitors level of fill. Further, when the expandable element  110  expands, the structure above the ground is elevated. Data such as the amount and level may be communicated through the second hole  116  to a device (not shown) operated by a user. Based on the data, the user may manage the pressure at which the composition  114  is pumped into the filler tube  112 . The expansion element  110  expands to cooperate with softer pockets in the soil, thereby, creating a support column underground. The pressure that composition  114  can be pushed directly into the ground or into expansion element  110  can be 2000 psi. 
     After the composition  114  is injected into the ground, the composition  114  improves the soil beneath the structure to create a resistance once the composition  114  permeates the soil and expand with the end result to fill any gaps or soft/weak pockets in soil  104 . In other words, upon injection, the composition  114  creates a stone or rock type material that supports the structural load of the structure, such as a house. In one embodiment, the composition  114  injected permeates the soil  104  and solidifies or permeates the soil  104  and expands by less than 3%. When the expansion is 3% or less it is known as permeation. When the expansion is greater than 3% the reaction and/or composition is known as expandable. It should not be noted that the composition  114  injected may or may not expand; and the reaction depends on the condition of the soil  104  as can be determined by sensors  120 ; 122  and/or engineers. In one example, the composition  114  may expand more than 3% and may further expand by more than 50%, and is not limited to the range specified above. Further, the arrangement explained above may be used to lift the structure in a consistent and permanent remediation with the help of the first sensor and the second sensor. A catalyst component can be added to composition  114  that can make it expand slower or faster. The catalyst component can be added to single or two component formulations. 
     The first hole and the second hole may be drilled to any depth, for example from 2 feet to more than 120 feet to insert the first pipe and the second pipe based on the requirement such that the composition is filled in the expandable element. Referring to  FIG. 2A , usage of a first pipe  206  and a second pipe  218  being used at greater depth is shown, in accordance with one exemplary embodiment of the present disclosure. Further, size of the first pipe may be in the range of 1/16 inch to 5 inches, however, the size of the first pipe is not limited to the range specified herein. The second pipe  218  may have first and second sensors  220 ;  222  at one end to sense the level of composition being filled in the soil. Referring to  FIG. 2B , usage of a first pipe  206 , a second pipe  218  and a third pipe  226  being used at greater depth is shown, in accordance with another exemplary embodiment of the present disclosure. The second pipe  218  may have a first sensor  220  such as a camera at bottom end to show the amount of composition being filled in the soil. Further, the third pipe  226  may have a second sensor  222  at bottom end sense the level of composition being filled in the soil. The data from the first sensor  220  and the second sensor  222  may be sent to a medium above ground (as shown in  FIG. 2B ) to view and control the pumping of the composition by a user. The rate of expansion can be controlled by the types of Resin A and B components used when the two component formulation is used or by the type of single component Resin that is used. The rate can be further controlled by the psi used to pump composition  114 . The type of catalyst component used also increases or decreases the acceleration of the reaction of the composition and thus the expansion of the expansion element when an expansion element is used. Although the figures show two sensors being employed, it should be understood that more than two sensors may be used to provide proper guidance or orientation to perform the above procedure.  FIGS. 2A and 2B  both show non-encapsulated embodiments. 
     In this embodiment, the first pipe  206  is raised as it releases the composition  114 . In the present embodiment, the arrangement does not comprise the expandable element. However, the composition  114  is injected directly into the first pipe  206  and into the soil  104 . 
     In operation, the retraction of the first pipe  206  and the injection of the composition  114  are controlled by the data received from the first sensor  220  and the second sensor  222 . Specifically, speed of the retraction of the first pipe  206  and the injection of the composition  114  are controlled based on the condition of the soil  104  and the information such as reaction time of the composition with the soil, collected by the first sensor  220  and the second sensor  222 . In other words, the speed of retraction of the first pipe  206  is controlled based on the pressure of the composition  114  being injected or the chemical reaction as detected by the first sensor  220  and the second sensor  222 . The composition  114  injected permeates the soil  104  and solidifies or permeates the soil  104  and expands by more than 3%. It should not be noted that the composition  114  injected may or may not expand; and the reaction depends on the condition of the soil  104 . In one example, the composition  114  may expand more than 3% and may further expand to more than 50%, and is not limited to the range specified above. 
     Referring to  FIG. 3 , a system for improving soil condition and or lifting a structure is shown, in accordance with another encapsulated embodiment of the present disclosure. At first, a first hole  302  is drilled in soil  304 . In one implementation, the first hole  302  may be drilled through a foundation of a structure such as a house or next to the foundation. In one example, the first hole  302  may be drilled at an angle of 90 degrees from the surface of the ground. In another example, the first hole  302  may be drilled at an acute angle from the surface of the ground. After drilling the first hole  302 , a first pipe  306  is inserted into the first hole  302 . The first pipe  306  is terminated on the downward end by a cap  308 . In the first pipe  306 , an expandable element  310  is inserted. In one example, the expandable element  310  is made up of a resin or polyurethane material or other components. Further, the expandable element  310  houses a filler tube  312 . In other words, the filler tube  312  is inserted into the expandable element  310 . The filler tube  312  is used to deliver a composition  314  into the expandable element  310 . 
     Subsequently, the first pipe  306  is retracted from the first hole  302  such that the expandable element  310  remains in the first hole  302  and the cap  308  remains in place at the bottom of the expandable element  310 . 
     Further, in proximity to the first hole  302 , two or more holes are drilled. For the purpose of explanation, the present embodiment is explained using two additional holes in proximity to the first hole  302 , however, it should be understood that more than two holes might be drilled in addition to the first hole  302 . Referring to  FIG. 3 , in proximity to the first hole  302 , a second hole  316  is drilled. The second hole  316  can be drilled in parallel to the first hole  302 . After drilling the second hole  316 , a second pipe  318  is inserted into the second hole  316 . The second pipe  318  at one end or proximity to the end may comprise a first sensor  320 . In one example, the first sensor  320  may be a camera. Specifically, the first sensor  320  may be a borehole camera. Similarly, in proximity to the first hole  302 , a third hole  324  is drilled. The third hole  324  can be drilled in parallel to the first hole  302 . After drilling the third hole  324 , a third pipe  326  is inserted into the third hole  324 . The third pipe  326  at one end or proximity to the end may comprise a second sensor  322 . In one example, the second sensor  322  may be a level sensor. Specifically, the second sensor  322  may comprise a theodolite. 
     When the composition  314  enters expandable element  310 , the first sensor  320  monitors the amount of the fill and the second sensor  322  monitors level of fill. Further, when the expandable element  310  expands, the structure above the ground can be elevated or lifted and the ground is stabilized. Data such as the amount and level may be communicated through cables the second pipe  318  and the third pipe  326 , respectively to a device (not shown) operated by a user. Otherwise, Bluetooth or Wi-Fi can be used to transmit the data. Based on the data, the user may manage the pressure at which the composition is pumped into the filler tube  312 . 
     Referring to  FIG. 4 , a system for improving soil condition and/or lifting a structure is shown, in accordance with another embodiment of the present disclosure. At first, a first hole  402  is drilled in soil  404 . In one implementation, the first hole  402  may be drilled through a foundation of a structure such as a house or next to the foundation. In one example, the first hole  402  may be drilled at an angle of 90 degrees from the surface of the ground. In another example, the first hole  402  may be drilled at an acute angle from the surface of the ground. After drilling the first hole  402 , a first pipe  406  is inserted into the first hole  402 . The first pipe  406  is terminated on the downward end by a cap  408 . In the first pipe  406 , an expandable element  410  is inserted. In one example, the expandable element  410  is made up of a resin, polyurethane material fiber, rubber, or any combination thereof. Further, the expandable element  410  comprises a first filler tube  412 - 1 , and a second filler tube  412 - 2 , is housed within second expandable element  411 . The filler tubes  412 - 1 ,  412 - 2 , collectively referred to as  412 , are used to deliver a composition  414  comprising of two different material, for example, an epoxy/resin mixture into the expandable elements  410 ; 411 . It is to be understood that only one expandable element may be used to receive the composition (from two filler tubes) or an expandable element may be provided for each respective filler tube if multiple filler tubes are used, depending upon the condition of the soil. Subsequently, the first pipe  406  is retracted from the first hole  402  while cap  408  remains buried, such that the expandable elements  410 ; 411  remain in the first hole  402  and the cap  408  remains in place at the bottom of the hole  402 . 
     Further, in proximity to the first hole  402 , a second hole  416  is drilled. The second hole  416  is drilled in parallel to the first hole  402 . After drilling the second hole  416 , a second pipe  418  is inserted into the second hole  416 . The second pipe  418  at one end or proximity to the end may comprise a first sensor  420  and a second sensor  422 . 
     When the composition  414  enters through the first filler tube  412 - 1  and the second filler tube  412 - 2 , both filler tubes are raised at predetermined rates of speed. The first sensor  420  monitors the amount of the fill and the second sensor  422  monitors level of fill. Further, when the expandable elements  410 ; 411  expand, the structure above the ground is elevated or lifted. Data such as the amount and level may be communicated through cables in the second pipe  418  to a device (not shown) operated by a user. Based on the data, the user may manage the pressure at which the composition  414  is pumped into respective filler tubes  412 . 
     Referring to  FIG. 5 , a system and method for injecting a composition is shown, in accordance with another embodiment of the present disclosure. The system comprises a first pipe  506  terminated on the downward end by a cap  508 , to protect the first pipe  506  from entering soil or debris. The first pipe  506  comprises an expansion element  518  having a smaller diameter than the first pipe  506 . The filler tube housed within expansion element  518  in this embodiment can have Y-mixer  528  at its bottom distal end. Multiple hoses  530  are located within the filler tube and are used to carry the composition through the filler tube. This allows the present invention to be used with deeper distances since the separate reactive components of the composition can travel further down before they react. These components can include Resin component A and Resin component B that travel through separate hoses and only mix deep in the soil in Y-mixer  528 . The Y-mixer can be implemented at the bottom end of the filler tube with or without the expansion element  518 . Instead of Y-mixer  528 , the system can use two hoses  530  to deliver the composition separately through a filler tube and into the soil. 
     The embodiments shown in  FIGS. 5A and 5B  allow first pipe  506  and expansion element  518  to go deeper into the soil, without mixing the materials until they are out of the respective hoses and combined in Y-mixer  528 . The different materials may be pumped through a single hose or separately into the second hose. Y-mixer  528  can include a third hose for a third material to be mixed therein. The different materials pumped may react only once they reach the Y mixer  528 . The above arrangement allows controlling reaction of the soil either slowly or fast in any type of soil and at any depth. Further, the different materials may be pumped at separate intervals to initiate the reaction of the different materials upon mixing in the Y mixer  528 . The pipes and hoses used may include one of a plastic, rubber, pvc and metal. 
     In one implementation, at first, the cap  508  is installed in the ground at the desired depth, e.g., 100 feet after drilling a hole. Subsequently, the first pipe  506  is hammered into the ground. Further, the hoses  530  present in the expansion element  518  may be connected to the Y mixer  528 . The hoses  530  are taken in such a way that the length of the hoses  530  is substantially same as the expansion element  518 . In one example, an epoxy/resin mixture may be pumped into one hose and a grout may be pumped into another hose within the same filler tube and having Y-mixer  528  at its bottom end or only hoses  530  within the filler tube. After pumping, the Y mixer  528  receives different materials through openings at one end and mixes the different materials. Upon mixing the different materials, the Y mixer  528  delivers the mixture onto the bottom of the opening. The amount of the materials injected in the soil may be monitored using sensors (first sensor and second sensor as explained above) to control the pumping of the different materials. In other words, speed of the injection of the materials may be controlled using the sensors. Specifically, the injection of the different materials is controlled based on the condition of the soil and the information collected, such as the chemical reaction as detected by the sensors. After injecting the mixture into the soil, the Y mixer  528  may be raised through the expansion element  518 . 
     In another implementation, at first, the first pipe  506  may be introduced into the ground along with the cap  508 . Subsequently, a plurality of hoses  530  may be provided inside the expansion element  518  or outside of it. In the present implementation, the arrangement does not comprise Y mixer  528 . In other words, the hoses  530  inside or outside the expansion element  518  run the length of the first pipe  506 . 
     After connecting the first pipe  506 , the expansion element  518 , and the hoses  530 , composition may be injected separately through the hoses  530 . The composition injected separately through the hoses  530  is delivered into the first pipe  506  and into the soil. While the composition is being injected into the soil, the first pipe  506  is raised, thereby leaving the cap  508  at the bottom. The speed of retraction of the first pipe  506  and the injection of the composition separately is controlled based on the pressure of the composition being injected or the chemical reaction as detected by the sensors (described above). As evident from the description, different materials may be pumped through different hoses. For example, a 3-part epoxy/resin mixture may be pumped into one hose and a grout may be pumped into another hose. The composition injected gets accumulated in the soil. Further, the composition may react with the soil and/or other composition when gets into contact. The chemical reaction and the amount of the composition being injected may be controlled using the information collected by the sensors, inserted in the second hole. Further, the speed at which the composition is pumped and the speed of retracting the first pipe  506  is controlled using the sensors. 
     An encapsulating method to stabilize soil including:
         j. Drilling a first hole into the soil under a structure;   k. Inserting a first pipe into said first hole, said first pipe having a removable cap at its bottom end;   l. Drilling a second hole into the soil under a structure and adjacent to said first hole, inserting at least one sensor into said second hole;   m. Inserting an expansion element into said first pipe, said expansion element including a filler tube housed therein;   n. Pumping a composition into said filler tube;   o. Raising said first pipe out of said soil;   p. Raising said filler tube within said expansion element thereby allowing said composition to be released into said expansion element, thereby expanding said expansion element;   q. Monitoring said expansion and solidification of said expansion element using said at least one sensor;   r. Completely removing said filler tube out of said expansion element, thereby leaving said removable cap and expanded expansion element in said soil.       

     The non-encapsulating method to stabilize soil includes:
         g. Drilling a first hole into the soil under a structure;   h. Inserting a filler tube into said first hole, said filler tube having a removable cap at its bottom end;   i. Drilling a second hole into the soil under a structure and adjacent to said first hole, inserting at least one sensor into said second hole;   j. Raising said filler tube to be removed from said cap;   k. Pumping a composition into said filler tube allowing said composition to be released into said soil;   l. monitoring said expansion and solidification of said composition using said at least one sensor;
 
Completely removing said filler tube out of said soil, thereby leaving said removable cap in said soil.
       

     The above arrangement allows controlling reaction of the soil either slowly or fast in any type of soil and at any depth. Further, the different materials may be pumped at separate intervals to initiate the reaction of the different materials when they reach the soil. 
     It is to be noted that the above embodiments are provided for illustrative purpose and should not be construed to limit to the embodiments explained, but the present disclosure is applied for any improving soil condition and/or to lift the structures. Further, the dimensions of the first pipe, second pipe, hoses and other components may vary depending on the implementation of the present disclosure and the ranges specified in the specification is not restricted to the embodiments presented. 
     The composition comprising of various materials may be used depending upon the condition of the soil and the structure. The composition improves the soil beneath the structure such as house, building, to create a resistance once the composition permeates the soil. Further, the composition may also be injected into a pile that does not permeate the soils such that the pile creates a column or pile to support the structural load. 
     In addition, sensors such as lasers and any other equipment may be used to monitor the lifting and/or variation of the existing levels that are being injected or used at the time. In an alternate embodiment, the filler tubes in the above-mentioned embodiments can include a plurality of through-holes that allow the composition to flow out of the through-holes. In an alternate embodiment the composition can be pumped directly into the ground using at least one hose. This embodiment does not use the expansion element. This embodiment can be implemented with the Y-mixer so that various components such as Resin component A, Resin component B, sand, soil, cement grout, or a combination thereof can each have their independent hose. This allows the components to travel deeper before reacting instead of a two component formulation using Resin components A and B, a single component can be used in combination with sand, soil, and/or cement grout. It can also be used by itself further a catalyst component can be used with either the single or two component formulation. The catalyst can be used with or without the expansion element. 
     In the preceding specification, the present disclosure is described with reference to the specific embodiments. However, it will be apparent to a person with ordinary skill in the art that various modifications and changes can be made, without departing from the scope of the present disclosure. Accordingly, the specification and figures are to be regarded as illustrative examples of the present disclosure, rather than in restrictive sense. All such possible modifications are intended to be included within the scope of present disclosure.
