Chemical Grouting

What is Chemical Grouting?

Chemical grouting is when chemical are mixed with water and reagents, such as sodium silicates, or various urethanes for permeation into dense granular soils for excavation shoring or to increase bearing capacity.

The Process of Compaction Grouting

The process requires at least one of several options. Various materials, includes acrylamides, have different strengths, viscosities, and costs. The most common type is a gelation of sodium silicate used with a hardener. Polyurethanes and acrylates compose the majority of the rest.

The process does not simply fill fractures; it is forced within each joint, crack, and into the soil where it solidifies to form a waterproof mass.

It can be used to reduce ground water intrusion through walls and around piping inlets. Holes are drilled and chemical grouting is injected along the flow paths, sealing the interior of walls and preventing water flow through them.

Where to use Chemical Grouting?

Often times you would use chemical grouting in storm sewer drain lines, transportation tunnels, foundation supports and many other places. If you're looking for a company who is experienced in chemical grouting, give the Judy Company a call today.
