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.
Underpinning rests your property’s foundation on underground steel piers. These steel piers safely and permanently transfer the weight of a structure onto solid bedrock or load-bearing strata. In some cases, Helical Pier installation is used for shallower stabilization of load bearing walls. For additional stabilization, Injection Piers combine Compaction Grouting and Underpinning Foundation methods for the most stable foundation repair.
Helical Pier installation is ideal for stabilizing existing structures that have been damaged due to settlement. The weight of a structure's load bearing walls is transferred off the weak soils and onto the helical piers. Every Helical Pier Project completed by Helicon comes with a Firm Foundation Warranty.
Sometimes foundations shift because the upper level soil is loose. Underpinning lifts and re-levels homes by driving steel piers into solid bedrock, safely and permanently transferring the foundation's weight load. Every Underpinning Pier Project completed by Helicon comes with a Firm Foundation Warranty.
Injection piers are one of the most stable methods of foundation repair, injecting a grout solution, through pins, into the ground to create a stable foundation. Every Injection Pier Project completed by Helicon comes with a Firm Foundation Warranty.
