Landfill Excavation Materials Handling Waste Treatment Soil Stabilization Civil Construction SOIL STABILIZATION KCOM provides stabilization/solidification (S/S) operations, both ex-situ and in-situ. KCOM reviews the characteristics of each project to determine the most effective method of treatment before selecting or recommending mixing techniques to our clients. KCOM typically uses a pugmill-mixing device to accomplish ex-situ S/S, though smaller projects can be completed via hoe mixing (i.e., mixing with an excavator bucket). Organic, inorganic and metal-contaminated soils are excavated and processed through a dual-shaft pugmill to mix the soil completely with the selected stabilization reagents. Reagents, such as portland cement, are added into the pugmill at the desired metered rate to achieve stabilization of the impacted materials. We also have the capability to conduct in-situ S/S using techniques, such as backhoe mixing, single-auger mixing, rake injectors and high-speed rotating mixing devices. KCOM also performs deep soil mixing using a crane-mounted auger system to drill into affected soils and uniformly mix the soils with cement additives. Equipment used for mixing primarily consists of a grout mixing plant, a grout pump and a mixing rig. Contaminants are encapsulated in a monolithic solid with high structural integrity, which minimizes contaminant migration. Similar results for stabilization of shallow soils can be achieved through the use of high-speed rotating mixing devices. These attachments can be fitted to heavy equipment (i.e., excavators and bulldozers, respectively) to stabilize impacted material. ph: (800) 886-8966 email: aedington@kcomenvironmental.com Indiana Headquarters - 1021 East Wallace Street, Fort Wayne, IN 46803 Illinois Headquarters - 1201 W.
