PU Injection Grouting

Product Description

Polyurethane grouting is a fast, economical repair process for correcting settled and unstable concrete.From sidewalks to interstates, and everything in between, polyurethane grouting is economical, fast and effective for correcting settlement and instability.  

How Polyurethane Grouting Works

Two polyurethane liquid components are mixed and injected (hence also being called polyurethane injection) under pressure below the area or structure being repaired. The two liquids react with each other, expand and harden, like the foam you get in a can to seal around windows.Our 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.The grouts we use, are specially formulated to be very strong and long-lasting in contact with the ground.

Advantages of Polyurethane Grouting

There are lots of advantages to polyurethane grouting as compared to other methods of repair, such as slab jacking, grinding and replacement. Polyurethane grouting has primarily been used in the infrastructure and industrial markets,for many jobs, such as lifting and stabilizing interior floors,polyurethane grouting is almost unquestionably the best repair process available.  Polyurethane grouting is Cleaner

Polyurethane grouting is the cleanest concrete lifting and stabilization process.Because the injection equipment is mechanically connected to the slab or structure, and mechanical seals engage when not injecting material, no loose material is introduced to the repair area.  Dustless drilling is easily accomplished, and even non-dustless drilling is essentially mess-free due to the small hole size. There is no grout or mud to track around job sites.
