XQ-GF Epoxy Crack Grouting Adhesive


XQ-GF Epoxy Crack Grouting Adhesive

Mainly used for concrete crack grouting,repairing,reinforcement of beam, floor, pole and basement of building, bridge and roadway. It is two components injection adhesive, mainly with modified epoxy resin and can be hardened at room temperature.

Range of Application

Repairing and reinforcement of the concrete crack on outer and inner walls, roof, beam, pole and floor.

Repairing the hollow parts of the wall and ground of cement and mortar, ceramics and stones Crack repairing for the concrete buildings, such as prefabricated components, equipment, silos, reservoirs, dams, bridges, tunnels, pipes, concrete pavement.


  1. Effectively seal the crack and improve the durability of concrete;
  2. Waterproof, corrosion resistance, ageing resistance;
  3. Low viscosity, fluidity, can be applied to cracks smaller than 0.05mm;
  4. After curing has excellent toughness and impact resistance;
  5. Easy to handle, short maintenance period with reliable quality.

Processing Flow

Crack confirmation and marking → Crack treatment → Seal the crack and fix the injection gun base

→ mix the adhesive according to the ratio → low pressure injection → hardening and maintenance


The interval setting according to the crack width as blow:
