HOME ABOUT US WHAT WE DO CONTACT CAREERS HYDRO EXCAVATION SERVICES Hydro-Excavation, or hydrovac, is the process of using pressurized water to excavate material. The resulting slurry is then removed using a powerful vacuum system. Hydro-excavation is minimally invasive, fast, and effective. It is the ideal option for any of your digging needs, including: Utility Pole Installation Trenching Interior Excavation Landscaping As well as many more. LoJac’s trucks are specially equipped to conduct hydro-excavation operations at any temperature, making them perfect for work in freezing conditions. LoJac has been in business for over 30 years, and has become one of the premier hydro-excavation service providers in the greater Nashville area. We are proud to provide hydro-excavation options to various projects, both new construction and restoration. How Does Hydro Excavation Work? Hydro excavation, or hydro vac, is the process of using pressurized water to dig and move dirt. Together, the high-pressure water breaks up the ground soil and the air vacuum transfers the slurry into the debris tank. Hydro excavation only uses pressurized water and an air vacuum system to complete the hydro excavation system. To utilize a hydro excavation unit, you will need a vacuum source, in which there are two options to achieve this. One is a fan framework and the other is a blower with a positive displacement capacity. The fan framework option is able to move an enormous amount of air. This allows for quicker excavation work and is easier to operate. This option is usually the less expensive route, compared to the positive displacement blower option. Displacement blowers are able to move air at a longer distance than the fan framework is able to. On top of that, a displacement blower allows excavation to be performed at greater depths, but it is at a slower rate. The fan system allows for hydro excavation work to be completed more effectively, but the displacement blower is good for deeper jobs. Sign, Pole, and Line Installation: Hydro excavation is utilized for line, sign, and pole areas for its installation. It is similarly used for potholing or daylighting. It takes into consideration less congestion and traffic in the excavating region because hardware can be placed a good distance. Funnel and Sewer Recovery: Funnel and sewer recovery is another application for hydro excavation. This strategy reduces dangers for any harm or punctures in the funnels. This eliminates the extra time and cost that fixes require. Landscaping: By utilizing hydro excavation for landscaping, exact excavation is done so the surrounding soil isn't upset. The soil remains compact and solid while the important evacuation and is finished. Soil Trenching Hydro excavation is utilized for soil trenching as well. Soil trenching is the process of digging narrow trenches in order to install cables, pipelines, and other types of in-ground utilities. Hydro excavation makes sure that the area that needs to be excavated is going to be altered because the unit has that capability with its exact precision. Also, a hydro excavation (or hydro-vac) is able to perform soil trenching work on frozen surfaces. They allow operators to use either cold or warm water to break down the frozen ground. Then they can vacuum everything into the attached debris tank. If you are looking for an efficient and non-destructive method of soil trenching, hydro excavation is the best option. Debris Removal Hydro excavation trucks are able to remove debris and clean out structures without affecting any surrounding structures. Traditionally, excavation equipment will need a larger area to work in to be able to be used properly. However, hydro excavation trucks have a boom component that is flexible and maneuverable more than traditional excavation equipment. The controls are at the operator’s fingertips, allowing them to control the boom’s exact height and depth. Hydro excavation equipment is able to remove both wet and dry forms of debris, which includes sand and rocks. Advantages and Benefits Hydro excavation carries various advantages to the mechanical field. It is currently the most used strategy for digging because of its productive and precise outcomes. The essential advantage of hydro excavation is that it offers better harm and security control when compared with other industrial techniques. Since it is exact, it limits accidents and wounds for workers and others in the surrounding area. It also provides super digging. Utilizing hydro excavation maintains a strategic distance from harming underground funnels, lines, and links. This kills the high costs required for repair and restorations. The need for fewer repairs implies an ideal opportunity for business running. Interrupted with utilities bring burdens and high expenses. This procedure of excavation can limit damages. Safety Benefits of Hydro Excavation Hydro excavation gives a method of digging and moving soil in a more secure way. It is a non-technician and non-damaging method. The workers will be protected from machinery accidents and the residents close by will be safe from construction accidents. Hydro excavation units include a high-pressure water hose and an air vacuum. In order to reduce clogs and traffic at the excavation site, the hydro excavation unit is able to be located further away from the excavation area. Cost Benefits of Hydro Excavation The procedure of hydro excavation lessens many undesired impacts from traditional excavation strategies. It gives exact and precise work so harms to the encompassing pipe, utilities, and condition are significantly decreased. For potholing, hydro excavation is able to move soil in a more accurate manner than other forms of excavation to install pipes and cables. The pipes and underground utilities will not be affected or harmed by the process because the water avoids the pipes, which prevents cracks or leaks.
