Injection chemical waterproofing:
A low viscous injection resin for waterproofing application in low to medium infiltration. This type of waterproofing method can be used in bricks, wet concrete, and other damaged structures, as basement, tunnels etc. In this way, a chemical is injected in victim areas which penetrate through the holes and cracks and blocks the travelling path of water.
Injection is often the most practical solution to restore the structural and/or waterproofing integrity of your concrete structure. If left untreated, the surface could fail completely, causing moisture incursion, concrete failure, or other catastrophic outcomes.
Polymer injection is a process whereby waterproofing material is forced under great pressure into cracks in concrete and the best solution for seepage and leakage. When properly performed, the repaired crack is actually stronger than the adjacent concrete, and the integrity of the surface is restored. The injection process is also utilized when water flows through cracks in buildings, especially in below-grade situations where access to the exterior of the surface is not practical. By injecting the crack with a polymer, not only is the integrity of the concrete restored, but also the water penetration is eliminated.
Chemical grout injection is utilized when water penetrates a surface, but not necessarily via identifiable cracks, or when there are so many cracks that injecting each one individually is not cost effective. Using this procedure, an expanding waterproofing grout is injected through a wall surface, to the back (exterior) side of the surface. When the chemical grout encounters water or moisture, it expands to many times its original size. This grout can lay dormant for extended periods, in an “un-activated” state until it encounters water.
