GROUND IMPROVEMENT SOLUTIONS

What is Grouting?

Grouting is an essential ground improvement technique used to enhance soil strength and stability. It involves the injection of cementitious or chemical grout into the ground to fill voids, compact soil, and mitigate settlement.

At GeoStabilization International, we specialize in a range of grouting services, including compaction, slurry, permeation, and chemical grouting. With over 20 years of experience, our team provides customized solutions designed to meet each project’s unique geotechnical and environmental requirements.

Our techniques strengthen foundations, repair sinkholes, and improve soil density, helping prevent costly damage and extending the life of infrastructure.

Improve Your Soil Strength with Our Grouting Techniques

Enhance the stability of your soil with our proven methods, each engineered for specific ground conditions and project goals.

 

Compaction grouting

Compaction Grouting

A ground improvement technique that injects a low-mobility cementitious grout at high pressure to densify and compact surrounding soils. This process forms stiff, bulb-shaped columns that strengthen the subsurface and reduce settlement.

Applications include:

  • Repairing sinkholes and voids
  • Strengthening soil beneath existing structures
  • Mitigating liquefaction risks
  • Controlling settlement for new construction

Slurry Grouting

This method involves injecting neat cement grout, mixed at precise proportions, into open-graded soils such as gravel or fractured rock. This method improves in-situ soil characteristics, controls water seepage, and increases load-bearing capacity.

Applications include:

  • Underpinning existing foundations
  • Reducing groundwater infiltration
  • Stabilizing excavations and underground structures
  • Improving support around utilities and below-grade infrastructure

Permeation Grouting

Microfine cement or chemical grout penetrates small cracks and fissures in the soil, creating a solidified mass that supports loads and prevents movement.

Applications include:

  • Controlling groundwater seepage
  • Underpinning and strengthening foundations
  • Increasing bearing capacity of granular soils
  • Shoring excavations or retaining walls

Chemical Grouting

This method uses resin-based or chemical compounds to improve soil structure and control water flow. These materials bind soil particles, seal cracks, and form impermeable barriers within granular soil or rock.

Applications include:

  • Repairing fractures in concrete and rock
  • Creating watertight barriers in permeable soils
  • Increasing bearing capacity in granular foundations
  • Preventing groundwater intrusion and leaks

At GeoStabilization International, our chemical grouting services are performed by experienced crews who customize each solution to site conditions and performance requirements.

Transformative Project for Homeowner in Minnesota

Just wanted to say that somehow your workers/artists took an ugly and scarred piece of this earth and turned it into a very pleasing and contoured piece of this earth. It looks incredible!! The fellows were all so nice and just wonderful to us. They worked so hard and were always hear early…….no goofing off…. just working. My husband suffered a traumatic brain injury in early 2012 and it has been a rough couple of years. He is almost completely healed. There were many tears and a lot of frustration. Seeing this project and the amazing workmanship put into it has really put a smile on our face. We thank your fathers for getting this company up and running. We thank you and Tim for keeping it running. Your company made a difference in our life and one we will not soon forget. It is easy to say thanks…it is hard to put into words.... but know that our thank you comes from the heart!!!

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!
