DrucHyd – 1C is a hydrophobic grout based on polyurethane. Upon contact with water, DrucHyd – 1C reacts to closed cell rubber like foam while expanding its volume up to 27 times. The cured material is of a constant volume. Since water is not a component of the foam structure, the cured material is essentially not affected by water or dryness. The reacted material does not shrink or swell. Depending on the pressure of injection, DrucHyd – 1C reacts to form a very dense material of foam.
The main fields of application of DrucHyd – 1C are as follows:
- Defective concrete (cracked or honeycomb)
- Concrete joints, Limestone, Brick construction
- Pipe instrusions, waste water tanks
- Tunnels, Dams, Subway, Sewers, Manholes, Utility boxes etc
- Soil stablization
Advantages of DrucHyd – 1C are as follows:
- Negative side application possible
- Deep penetration into very small cracks
- Foam increases in volume to fill cavities and voids
- Excellent bond to surfaces
- Good adhesive strength, tolerant of movement Inert after curing, constant volume, no shrinkage
- Does note create new cracks
