What is Grouting?

Grouting is a ground improvement technique that injects cementitious or chemical materials into soil to fill voids, compact ground, and increase strength. At GSI, we specialize in:

  • Compaction Grouting

  • Slurry Grouting

  • Permeation Grouting

  • Chemical Grouting

With over 20 years of experience, we match each technique to site-specific conditions for maximum effectiveness.

Compaction Grouting

Compaction Grouting

High-pressure injection of low-mobility cementitious grout compacts surrounding soil, forming stiff grout columns. Used for sinkhole repair, settlement control, liquefaction mitigation, and improving soils under structures.

Slurry Grouting

Slurry Grouting

Neat cement grout fills voids in open-graded soils or bedrock, improving material characteristics, reducing seepage, underpinning structures, and increasing load capacity.

Permeation Grouting

Permeation Grouting

Microfine cement permeates cracks and fissures, solidifying the soil to support higher loads, fill voids, and control water seepage. Ideal for underpinning and excavation shoring.

Chemical Grouting

Chemical solutions bind granular soils, repair concrete and rock fractures, and form waterproof masses to stop water movement.

Client Reviews

Foundation Grouting and Structural Repair for Homeowner

I wanted to drop you a quick note. Late last year I had Tom Szynakiewicz come by and advise me as to what I needed to do to fix my house structure. Tom and GSI were great to work with to find a solution for my structure issues. GSI did an excellent job for us and got us on the right track with the work that was performed. We just sold the home last week, and disclosed the work that was done. We had zero issues with selling the home because it was fixed by GSI. I am very thankful I called and got you guys involved! Thanks again for steering me in the right direction Wayne!
