Crack Repair & PU Filling

Professional crack repair combined with PU (polyurethane) filling ensures permanent sealing of cracks and joints, preventing water infiltration and structural damage in walls, slabs and joints.

Procedure:

1. Crack preparation — clean and slightly widen each crack to open a sound channel for the sealant.
2. PU injection — inject or fill the cracks with polyurethane foam or sealant, which expands to seal the gap permanently.
3. Finishing — smooth and level the repaired area for a clean, watertight surface.
