HydroSeal 103 2K

Cementitious waterproofing membrane with high adhesion that can be applied very quickly by airless spray. For reservoirs, water tanks, below ground structures, podium decks, balconies and parking areas.

Capable of resisting extremely high positive and negative water pressure. HydroSeal 103 2K forms a hard, highly alkaline coating with a degree of elasticity which has greatly enhanced chemical resistance and so is particularly suited for the protection of concrete within sulphate contaminated ground.

It has excellent resistance to the ingress of acid gases, moisture and chlorides to enhance the durability of reinforced concrete and protect highway and coastal structures from chloride attack. HydroSeal 103 2K is reinforced over static joints and at details and changes of direction with HydroSeal 912-RT.
