Pressure Grouting

Pressure Grouting Through Atlanta, Georgia and Southern SoilsDiagram of how Pressure Grouting Works

Foundation problems often arise when the soil beneath your property is too weak to support the weight of the structure. Foundation piering is one option we use to solve this problem, but it is not always the most expedient or economical solution, depending on your unique soil and structural issues. Pressure grouting, also known as permeation or compaction grouting, can actually strengthen soil that is weak or has broken apart over many years. This is the direct injection of grout to fill the space in between soil particles. The actual process of pressure grouting involves placing hollow pipes three to five feet apart in the soil until hard dirt is reached, at which point the grout, a rockless concrete, is forced through the pipes. This blends with the soil and fills in all the particles, making it more compact and strong enough to support your foundation.

 

Pressure grouting is chosen after carefully surveying your soil and foundation. It is an extremely flexible solution to foundation leveling, since different tools and methods can be chosen depending on a number of things, from the size of the structure that needs stabilization to the area of the soil where pressure grouting needs application. For instance, for commercial work a drill rig would be most suitable, while for a small residential foundation, a hand drill combined with a metering pump may be the best choice. Although widely applicable, there are some standard factors that may lead to the use of pressure grouting:

  • Does your home or property need to be releveled?
  • Does the ground beneath your settling structure need to be improved?
  • Are there rock cracks that need to be filled?
  • Do footing soils need to be densified?

The versatility and flexibility of pressure grouting makes it a popular and often ideal choice when a structure needs to be stabilized with foundation repair. When access to soil is limited because of the structural design or heavy equipment, pressure grouting can easily reach the soil simply by shifting pipes and angles under the ground. It is also a quiet solution, meaning that you can carry on with your normal routine without much disruption. Certainly your neighbors will appreciate that, too!
