Compaction Grouting

Compaction Grouting

American Foundation & Basement Repairs, LLC has many ways to provide you with sinkhole repair. Compaction grouting or soil stabilization is one of the preferred methods and is done by pumping cement into the ground through steel casing under pressure to fill the voids or pores in the limestone. Once the voids or pores are filled, then compaction of the upper soils will be done, by compressing the soil with the cement. Starting at the limestone area, the steel casing will be extracted, while pumping to compress the soil from limestone to the surface. We provide this service to the Knoxville, Chattanooga, Asheville, Johnson City, and Cookeville areas.

This is completed by doing the following the steps: American Foundation & Basement Repairs will use its state of the art drill rigs which were designed to work in all types of areas to drill down to limestone utilizing three inch diameter steel casing - (these are called grout injection points). Once the grout injection points are installed, we will then have a pump crew mobilize to start pumping the cement through each injection point, one by one, until all of the injection points are completed.

What Is Surface Compaction & How It Helps

Surface compaction is done by pumping cement into the upper 5' to 10' soils. This is designed to permeate the upper soils to compact them. This is completed by installing small diameter steel casing up to 1.25 inches. Using the small casing, we will inject portland-based cement grout under low pressure and low volume to prevent damage to the structure. American Foundation & Basement Repair's sinkhole crew can also use chemical grouting, which can be either epoxy or polyurethane resin for shallow-surface compaction projects. It is important to note that his type of repair is very different from one that involves foundation piers and will provide a repair that is more attuned to the sinkhole problem.
