Why Flexstone?

Flexstone is Canada’s premier sundeck waterproofing system. The rugged one-of-a-kind membrane is a simple-to-apply common-sense solution for sundecks, flat roofs, garage floors and more. Flexstone is seamless, attractive and CCMC approved for applications over living space.

Unlike other liquid applied coatings that are highly solvated and go on thin, the Flexstone base is an environmentally friendly, low VOC product that is troweled on thick to give you the ultimate waterproofing protection you deserve to protect your home.

This product is long lasting, seamless, and aesthetically pleasing. We are happy to be part of the Flexstone Dealer network, offering this product to residential and commercial clients in the Edmonton area.
