Product description
Specifications special addictive for permable concrete
It is a patented additive to concrete. It can be mix without sand. When cured, it enhance strength of concrete and allows it to be porous. The permeable pavement surface with underlying aggregates can form a temporary reservoir. The reservoir temporarily stores surface runoff before infiltrating into the subsoil or sub-surface drainage and in the process improves the water quality. Porous pavements allow the earth to breathe, take in water and be healthy. The stone and soil under them acts as a reservoir and they clean the water a little like the filter on the fish tank. They are quieter and safer to drive on as they do not develop water ponding on the surface and provides good tires grip. When the ground holds the rainwater, during hot days, the water evaporates and the surface is cooled. The area above the surface will have lower temperature.
