Compaction Grouting, otherwise known as soil stabilization is accomplished by putting cement into the ground with steel casing under pressure to fill up any voids, holes, or pores in the limestone below. Once those voids are filled, the compaction of the upper soils will be completed and the soil will be compressed by the cement. Then, beginning with the limestone area, the steel is removed while pumping continues to fill all of the space below.
This is completed by doing the following the steps: first, we use specially engineered drill rigs which were designed to work in all types of areas to drill down to limestone using 3 inch steel casing - (grout injection points). Once the grout injection points are created, we will then have a pump crew mobilize to start pumping the cement into each injection point, one at a time, until all of the injection points are finished.
Shallow Compaction on Surface
Surface compaction is accomplished by putting cement into the upper 5' to 10' soils. This is designed to penetrate the upper soils to compact them. This is completed by installing small diameter (1.25”) steel casing. Using the small casing, we will inject cement grout under low pressure and low volume to prevent damage to the structure. Asheville Foundations & Basements' sinkhole crew can also use chemical grouting, which can be either epoxy or polyurethane resin for shallow-surface compaction projects.
