The Future of Waterproofing is HERE

Revolutionary Waterproofing

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 cool green 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 more than 25 years.

Seamless Membrane,
Easy To Apply

Liquid polyurethane applied as a seamless, monolithic membrane to a thickness of 1.50 – 2.00 mm. Simply mix two components, pour the mixture, and spread it using a paint roller to a specific thickness in one or two coats.

A special damp-tolerant Polyurethane Primer will seal the concrete prior to application of the main coat thereby allowing application even in high humidity environments.

Impermeable to Water &
Chemically Resistant

Drythane is completely impermeable to water and has very low water absorption in continuous immersion with a saturated weight gain of less than 0.60% as per Procedure 7.4 (Long Term Immersion) of ASTM D 570. Further, it is highly resistant to a wide variety of Acid, Alkali, Salts, etc.

These unique properties allow it to be used for continuously damp or wet applications such as rooftop gardens, ponds, storage tanks, swimming pools etc.

Tough and Durable,
Long Service Life

When cured, Drythane is a very tough, durable, elastomeric membrane with a tensile strength of more than 2,800 Psi and a hardness of 65 Shore D! As it cannot be damaged during normal use, you have no need for reinforcement or protection covering through masonry.

Further, it resists degradation from sunlight (UV), rain, heat & cold weather. Our high performance membrane provides a long service life of more than 25 years.

Crack Spanning &
Elastic Nature

Drythane is an elastic membrane with over 90% elongation. For cold climates, flexible surfaces, and substrates prone to cracking, we offer Drythane Plus with an elongation of over 350% . Additionally, it is unaffected by temperature cycling and will span cracks in concrete up to 2.50 mm.

Using 0.50 mm Drythane Plus as a base coat with 1.00 mm Drythane as the top coat will increase the crack spanning of the combination to over 10.0 mm+

High Adhesion

Drythane bonds strongly to the substrate. Thus, in pull off tests, the break takes place only within the concrete and not at the interface. Unlike sheet applied materials, liquid water cannot possibly intrude under our coating. Adhesion is usually an indicator of the service life — higher the adhesion, longer is the service life.

Optional Reflective Coat

Insulation from heat can be achieved by greening the roof (with drainboard, soil and grass) after applying our products! However, if a green roof is not desired but you still want to reduce indoor temperatures, you can simply apply an optional aliphatic, colour fast, and heat reflective top coat.
