Integral Waterproofer

Larsen Integral Waterproofer is a standard-setting, ‘pore–blocking’, permeability-reducing admixture.

It inhibits the passage of liquid water through the capillary and pore network in cementitious materials, but does not form a vapour barrier thus allowing the structure to breathe. Larsen Integral Waterproofer is non-retarding, chloride-free and equally compatible with all cements. Larsen Integral Waterproofer can be used to waterproof screeds, renders and concrete, which when treated will resist hydrostatic pressure. It is also suitable for use in render systems used to tank basements or to line water-retaining structures.
