CCS HiAmb IR

CCS HiAmb IR – High Ambient Temperature Epoxy Adhesive for Pressure Injection Grouting. This is a two-component, low-viscosity, structural epoxy adhesive designed for pressure injection grouting and crack repair in high ambient temperature conditions. It is ideal for structural repair of cracks and delaminations in concrete, masonry, stone, and sealed wood. It is also suitable for anchoring applications and adhesive bonding of steel reinforcement.
