High Strength Epoxy Crack Repair Sealer For Concrete Restoration
Concrete Crack Repairing Grout Epoxy
Crack Repair Grouting adhesive
XQ-GF 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.
Features
- Effectively seal the crack and improve the durability of concrete;
- Waterproof, corrosion resistance, ageing resistance;
- Low viscosity, fluidity, can be applied to cracks smaller than
0.05mm;
- After curing has excellent toughness and impact resistance;
- 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:
Crack width (mm) | Interval (mm) |
| Min. | Standard | Max. |
| 0.05-0.2 | 150 | 200 | 250 |
| 0.2-3.0 | 250 | 300 | 350 |
