Crack Injection PU Resin & Foam
Crack Injection PU Resin & Foam is a solvent-free, 2-part low-viscosity foaming polyurethane injection resin system (Part A Base & Part B Catalyst). Upon contact with water, it reacts rapidly to form a tough, flexible, semi-rigid closed-cell PU foam that effectively seals active water leaks, cracks, voids, and construction joints in concrete structures under high hydrostatic pressure.
Product Overview
This product range offers advanced material performance and long-term durability. Formulated to meet high standards of protection and reliability under various site conditions. Crack Injection PU Resin & Foam is a low-viscosity, fast-reacting polyurethane injection system engineered for deep penetration into micro-cracks and structural joints, expanding rapidly upon contact with moisture to form a durable, water-impermeable seal against high hydrostatic pressure.
Best-fit Applications
- Water sealing of active water leaks, cracks, and construction joints
- Sealing voids, honeycombing, and rock pockets in underground concrete
- High hydrostatic pressure water-stopping in below-grade infrastructure
- Flexible joint sealing and structural crack encapsulation
Technical Benefits
- Solvent-free, 2-part rapid reaction formulation
- Fast-expanding closed-cell PU foam upon contact with water
- Excellent adhesion to wet and dry concrete substrates
- Hydrostatic pressure resistance up to 5 bar head (no leakage)
Technical & Performance Specifications
Application Guidelines & Installation Method
Step 1: For epoxy-based repair mortar, clean the damaged concrete, mix components to the specified ratio, place and compact the repair mortar, finish to the required profile and cure.
Step 2: For PU crack injection resin and foam, clean the crack, install ports, seal the surface, check for leakage, inject at controlled pressure until filled and sealed, then cure and remove ports.
