POLYURETHANE GROUT INJECTION/WATER SEALING
Polyurethane grouting is cleaner, faster, and less disruptive than cement grouting. Two polyurethane liquid components are mixed and injected under pressure below the area or structure being repaired.
The two liquids react with each other, expand, and harden. Polyurethane grouts stay a liquid for a few seconds before expanding. This helps them spread out from the exact spot they’re injected, but then get harder much faster and can exert much more force during expansion than other options. High-density polyurethane is also waterproof, so treated slabs are thoroughly undersealed.
Polyurethane can also be installed in water, so flow testing or water-stop applications with active flows are not a problem. Because of the near-immediate curing, water-stopping jobs are fast and easily tested on-site to ensure the efficiency of the repairs.
