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.
With Next-Gen Properties
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.
Fully Impermeable to Water

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

Standard Drythane is a very tough, durable, elastomeric membrane with a tensile strength of more than 17 N/mm², hardness of 65 ShoreD, tear of 54 N/mm and puncture resistance of 1500 N! 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 are elastic membranes with industry leading crack bridging capacity ranging from 2.8 to 10.00mm! Products with higher elongation are more suited for flexible surfaces and cold climates and can be used as a stand alone coating or as a flexible base-coat underneath Drythane Standard. In case of the latter, the resulting system has a crack bridging of 8.00 mm while providing a very tough surface with outstanding water resistance - we call it the "Ultimate Combo".
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 Aliphatic 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.

Frequently Asked Questions
Can’t find the answer you’re looking for? Write out to our customer support team.
What makes Drythane's two-component system unique?
Our innovative two-component system consists of a specialized resin and activator that work together to create a superior waterproof coating. The magic happens when these components are mixed just before application, triggering a chemical reaction that ensures maximum stability and performance. This method guarantees that the coating maintains its effectiveness throughout its storage life.
Why is PIV Primer essential for optimal results?
PIV Primer is our breakthrough damp-tolerant polyurethane primer that creates an exceptional bond with concrete surfaces. Its unique formulation allows it to penetrate deeply, even in challenging high-humidity environments like coastal areas or monsoon seasons. This critical base layer ensures perfect adhesion and prevents common issues like outgassing and pinholing.
What sets Drythane's durability apart from competitors?
Drythane delivers exceptional longevity with a proven service life exceeding 25 years - that's 3-4 times longer than typical alternatives. Our optional reflective aliphatic coating provides additional protection and insulation benefits that maintain their effectiveness throughout the entire lifespan of the installation.
