Pressure Grouting

What is Pressure Grouting?

  1. There are many options for repairing leaks in concrete structures. One of the oldest, yet least understood repair methods uses polyurethane chemical grouts that react with water to either bond with the concrete to form watertight, permanent seals or to become rigid, filling voids and stabilizing soil.
  2. Polyurethane chemical grouts are usually injected under pressure as a liquid resin into or in the vicinity of the leak. Once the resin contacts water, a chemical reaction occurs. Depending on the material formulation, the grout/water combination forms either an expansive closed cell foam or a gel. The foam created can be flexible and resilient (hydrophilic) or ridged, meaning the cell structure of the foam crushes when compressed (hydrophobic).
