Underwater grouting is not one product type. Some repairs need anti-washout cementitious grout for larger voids and submerged structural filling. Others need underwater epoxy grout for dense repair and high bond below the waterline. In wet cracks, leaking joints and unstable voids, polyurethane systems may be the better route for sealing, void filling or support recovery.

ZRETE’s underwater grouting solutions are organized around these three material routes: cementitious underwater grouts, underwater epoxy grouts and adhesives, and polyurethane injection systems for wet or water-bearing repair zones. This structure makes it easier to choose the right route by water condition, gap size, bond requirement, curing behavior and long-term service demand.

Solution routes

• Cementitious Underwater Grouting Solutions for anti-washout filling, marine repair and submerged structural grouting

• Underwater Epoxy Grout & Adhesive Solutions for dense filling, underwater bonding and jacket-based structural repair

• Underwater PU Injection Grouting Solutions for wet cracks, void filling, slab undersealing and support stabilization

Typical project conditions

• Marine piles, piers, wharves and submerged concrete repairs

• Underwater filling and jacket-based pile rehabilitation

• Wet structural bonding and underwater crack repair

• Water-bearing voids, leaking joints and submerged interfaces

• Offshore foundations and underwater non-dispersible grouting work
