Product Overview

Conbextra EP10 is a two-component, low viscosity, solvent-free epoxy resin system for the structural reinstatement of cracks in concrete by low-pressure injection or vacuum injection technique. When injected into a concrete crack under low pressure, Conbextra EP10 penetrates fully into hairline cracks (as fine as 0.1 mm width) due to its very low viscosity, then cures to form a fully structural epoxy weld that restores the tensile and shear continuity of the concrete section across the plane of the crack. Unlike cementitious crack fillers that merely seal the surface, Conbextra EP10 injection creates a monolithic repair where the healed crack is stronger in tension than the surrounding concrete. It is used to repair structural cracks in reinforced concrete beams, columns, walls, slabs, bridge decks, tunnels, and foundations caused by overload, settlement, thermal movement, or construction defects. The crack must be dormant (non-moving) for Conbextra EP10 injection to be a suitable repair strategy — active moving cracks require flexible sealant repair instead. Space Arc Engineering distributes and supports crack injection using Conbextra EP10 for structural repair projects across Delhi NCR and Northern India.

Applications

• Structural crack repair in reinforced concrete beams and columns
• Crack injection in bridge decks and concrete girders
• Foundation and retaining wall structural crack reinstatement
• Slab and floor structural crack repair by injection
• Tunnel lining crack injection to restore structural continuity
• Post-tensioned slab crack repair by low-pressure epoxy injection

Key Advantages

• Very low viscosity penetrates hairline cracks down to 0.1 mm width
• Fully structural repair — restores tensile and shear continuity
• Cured strength exceeds the tensile strength of concrete
• Solvent-free — low toxicity and suitable for enclosed spaces
• Low pressure injection minimises risk of crack widening during repair
• Proven Fosroc technology for structural crack reinstatement
