FortisMate LR Series
LR-WPU is a single-component, high-elastic hydrophilic polyurethane grout. It reacts instantly with water, forming a flexible gel that rapidly seals and blocks water leakage paths. Ideal for emergency water-stopping in underground structures, tunnels, and concrete cracks.
Highlight: LR: Leakage-Repair；WPU: Water-based Polyurethane；Hydrophilic Polyurethane Grout
Core Advantages
Instant Water Reaction
Reacts immediately with water; cures into gel for fast leak sealing.
High Elasticity & No Shrinkage
Flexible, resilient, adapts to minor structural movement.
Single-Component, Easy Application
Ready-to-use; simple injection and cleanup.
Good Injectability
Works well in cold conditions; penetrates fine cracks.
Strong Adhesion
Bonds firmly to concrete, masonry, and metals.
Durable Water Stopping
Hydrophilic, long-term water resistance.
