Soil Stabilization

For deep sinkholes, Compaction Grouting fills voids and stabilizes weak soil down to the bedrock. Chemical Grouting is the safest and most accurate sinkhole repair method while densifying loose soils that exist within 15 feet of the surface.

This sinkhole repair method caps and seals the limestone surface, fills voids, and pushes into weak soil, compacting and strengthening it. Every Compaction Grouting Project completed by Helicon comes with a Firm Foundation Warranty.

The best solution for shallow sinkhole repairs is chemical grouting. It’s a good remedy for problems that occur close to the surface – where compaction grouting is not an option. Every Chemical Grouting Project completed by Helicon comes with a Firm Foundation Warranty.
