Pressure Grouting / Permeation Grouting

Foundation Support - Soil Stabilization

The term "Pressure Grouting" is in widespread use, but it is frequently misused. Although it seems to describe a specific type of grouting, the term is not specific. It refers to a wide variety of procedures. All grouting is done under pressure, so it is kind of like saying, "wet water". Permeation Grouting is a more precise term for what is commonly referred to as pressure grouting.

Permeation grouting is the direct pressure injection of a fluid grout into the ground to fill the spaces between particles.

Injection methods are tailored specifically to a project. Some jobs are well suited to drill rigs and high-rate batch plants; other jobs are better suited to hand drills and small metering pumps. Sleeve-port pipes and downhole packers are often used to isolate particular zones in a formation. The choice of materials offers hundreds of options, ranging from cement slurries to specially designed chemical solutions.

All these options provide a project designer with a wide range of alternatives. Any effective grouting program requires a thorough evaluation of these options. The challenge is to find the best combination of methods and materials to achieve all technical objectives, while accommodating other factors such as existing ground properties, cost and accessibility.

An effective grout program also requires a contractor with technical expertise to implement the project. Rembco has been designing and performing permeation grouting programs for more than 25 years. Rembco uses pressure grout methods for preventing water flow, stabilizing granular material, encapsulating contaminated material, and improving the physical properties of soil or rock. We have also effectively used permeation methods to fill voids, cracks, fractures, cavities, and to create barriers to the movement of liquids through the ground.
