Solvent Free, Thick Film, Liquid Applied, Polyurethane Waterproofing Membrane

About Drythane

Drythane is a 100% Solids, two component Polyurethane Coating system that contains no solvents, noxious smells and is non-flammable. It has been formulated specifically as a high performance waterproofing membrane. Drythane provides lifelong protection to concrete and other masonry. Once coated, the surface is completely impervious to water. With Drythane, you can create green and cool roofs of your dreams, with gardens, vegetation, water bodies, swimming pools etc. Applied as a thick film (1.50 - 2.00 mm), this premium, high performance product has an expected service life of 20 years and more.

Seamless Membrane, Easy To Apply

Liquid polyurethane applied as a seamless, monolithic membrane to a thickness of 1.50 – 2.00 mm. Simply mix the two components, pour and spread using paint roller to specified thickness in one or two coats. Special two component 100% Solids Damp Tolerant Polyurethane Primer will seal concrete prior to application of Drythane main coat. Can be applied even in high humidity environments.

Impermeable to Water, Good Chemical Resistance

Drythane is completely impermeable to water and has very low water absorption in continuous immersion. Saturated weight gain <0.60% as per Procedure 7.4 (Long Term Immersion) of ASTM D 570. This unique property allows it to be used for continuously damp or wet applications such as rooftop gardens, ponds, storage tanks, swimming pools etc. Drythane is also highly resistant to a wide variety of Acid, Alkalis, Salts etc.

Tough, Durable Film

Cured Drythane film is a very tough, durable, elastomeric membrane with tensile strength of approx. 2,800 Psi and hardness of 65 Shore D! Cannot be damaged during normal use – hence no need for reinforcement or protection covering with masonry. Resists degradation from sunlight (UV), rain, heat & cold weather. Provides a long service life of 20 years and more.

Elastic Nature, Crack Spanning

Elastic membrane with >50% elongation. It is unaffected by temperature cycling and will span hairline cracks in concrete. Brittle products such as Epoxy will simply crack in service.

High Adhesion

Bonds strongly to the substrate. In pull off tests, break takes place within the concrete and not at the interface. Unlike sheet applied materials, liquid water cannot intrude under the coating.

Optional Reflective Top Coat

Heat insulation can be achieved by greening (with drainboard, soil and grass) the roof after installing Drythane! If you do not want a green roof and want to reduce indoor temperatures, simply apply optional aliphatic, colour fast, heat reflective top coat over the Drythane main coat.
