Polyurea has quickly become the coating of choice when it comes to waterproofing in commercial, industrial and residential applications. Hygrothane, Elastochem’s waterproofing membrane, is the only Polyurea waterproofing system* on the Canadian market that meets and exceeds the Bitumen Standards for Roofing, and the National Building Codes—the current and only governing authority for waterproofing systems below grade.

A fast-curing, protective Polyurea waterproof coating, Hygrothane is an ideal solution for a wide range of substrates, such as concrete, metal and wood surfaces. Hygrothane_0002_Cropped.jpg

The many benefits of Hygrothane include:

Waterproof Protective Coating: Polyurea is highly resistant to water. It can be used as a waterproof coating for foundations, roofs and other surfaces. Its ability to form a seamless and impermeable barrier makes it an effective solution for preventing water infiltration and moisture damage.

Monolithic Barrier: Hygrothane is seamless, eliminating conventional seams that are subject to high failure rates leading to inevitable water intrusion. There is no limit on pass thickness, and it can also bridge cracks and seals joints. Excellent Adhesion: Creates an effective bond to a variety of substrates, including green concrete, metal, and wood. It is also extremely compatible with ICF blocks. Rapid Cure and Reduced Downtime: The membrane’s super-fast cure time allows for quick application to prepared substrates allowing for a quick return-to-service and minimal downtime.

Reduced Labour: The quick installation reduces labour time/man hours required on a project. Taping, troweling, multiple layers, torching and sealing are not necessary. The ease of application helps with faster turn-around times, and optimised project schedules.

Suitable for a Variety of Climates: Can be applied in a variety of cold and warm temperatures. Hygrothane is applicable to substrate temperatures as low as -5°C, regardless of ambient air temperature.

Extreme Durability & Toughness: Hygrothane is a pure Polyurea and is abrasion, impact, and chemical resistant.

Better for the Environment: Hygrothane’s waterproofing technology contains no volatile organic compounds (VOCs), is bitumen free, and qualifies for LEED points if needed.
