Betoseal PU
Betoseal PU is a high-performance, single-component polyurethane crack-injection resin. It reacts rapidly with water to form a semi-rigid or flexible foam to seal leaks and voids in concrete structures.
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. Betoseal PU is a high-performance, single-component polyurethane crack-injection resin. It reacts rapidly with water to form a semi-rigid or flexible foam to seal leaks and voids in concrete structures.
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
- • Tough, flexible seal withstands dynamic structural movement
- • High bond strength to concrete substrate under hydrostatic head

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.
