Sikadur®-53 - Epoxy Crack Injection And Grouting Resin
Verified by manufacturer 1 day ago
Epoxy crack injection and grouting resin for all conditions, including wet and underwater.
Application
- Crack injection resin to seal damp and wet cracks by high pressure injection.
- Fills and seals voids and cracks in structures such as bridges, civil engineering structures, industrial and residential buildings (e.g. columns, beams, foundations, walls, floors, water retaining structures, etc.).
- Structural bonding.
- Preventing ingress of water and infiltration of reinforcement corrosion promoting substances.
- As a grouting resin or adhesive for bonding concrete and steel underwater (by water displacement).
