BASEMENT WATERPROOFING
PU INJECTION GROUTING
It is a hydro phobic grout based on Poly-Urethane. Upon pounding with water it reacts to closed cell rubber like foam while expanding the volume up to 25 times. The huge 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, it reacts to a very dense material of foam.
Uses
Defective concrete ( cracked or honey combed )
Concrete joints, lime stone , brick construction
Pipe intrusions, waste water tanks
Retaining walls, Bathrooms, Patios
Terraces and balconies
Floor slabs
Water tanks
Advantages
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 not create new cracks
