Waterproofing a Concrete

Concrete is porous which absorbs water, waterborne contaminants and chemicals that can cause deterioration if not waterproof. Waterproofing of concrete is done by either suitable extraneous treatments like applying paints, fixing bitumen felts etc. or internally by suitable design of the concrete mix, addition of suitable admixtures in the concrete or mortar at the time of mixing and/or installing water bars at the joints. Requirement of /waterproofing Admixture for Concrete Water is the main important part of concrete through the making to placing procedure. After it gains its strength moisture or water penetration will harm the concrete if it remains in concrete. This can cause due to corrosion of reinforcement or due to freeze thaw. To come out of this problem porosity should be reduced. Concrete is porous material and water can go through the pores material and micro-cracks due to capillary actions. Thus there is a need of admixture which can control the po
