PC Tunnelinject 2K 6822 LV is a low viscous, fast reacting, two-component, polyurethane injection resin. This resin is developed for the consolidation and water sealing of structures with high water flow or pressure in shafts, tunnels, dams, canals, mines, … Also for the stabilization and water sealing of drill holes, porous rocks, sand, ground, brick and concrete constructions.
Properties
- Very low viscosity
- Sealing of hairline cracks
- Increase of 8 to 10 times in volume in wet structures
- In wet structures the product forms a very strong polyurethane foam
- In dry structures the product forms a solid mass (±70 MPa)
- Becomes completely watertight after curing
- Reinforces the treated construction
- Reacts via a pump effect after injection. Pushes itself into the porous rock or concrete structure that needs to be reinforced (principle of self-injection)
- 1/1 mixing ratio
