ACTFLEX ER300 – Low-Viscosity Epoxy Crack Injection Resin

ACTFLEX ER300 is a low-viscosity, two-component epoxy resin designed for pressure injection of fine to medium structural cracks in concrete. ACTFLEX ER300 penetrates deep into cracks from 0.1–1.0 mm, restoring structural integrity and permanently sealing the crack with no shrinkage after curing.

ACTFLEX ER300 is solvent-free and provides excellent adhesion to concrete, making it ideal for structural crack repair in slabs, beams, columns, bridges, tunnels, and industrial floors. Once cured, ACTFLEX ER300 forms a high-strength bond that prevents water ingress and protects steel reinforcement from corrosion.
