About us

Flexstone is a Seamless Waterproofing Membrane Installed on Concrete or Wood

During the 1990s in Vancouver, Flexstone experimented with various urethane waterproofing products to create a cold-applied waterproof coating that would benefit our customers and meet the requirements of engineers and envelope consultants. 

Using standard urethanes on sundecks in most applications found locally failed to meet our standards and was unpleasant to work with. The available products were solvent-based, thin, difficult to work with, and, most importantly, lacked the flexibility needed for our climate.

Flexstone is Canada’s premier sundeck waterproofing system and one of the country’s fastest-growing waterproofing systems.

FS Coatings and Flexstone Ontario combined to provide materials to dealers in Ontario, Quebec, and other Eastern provinces, including Bermuda, Jamaica, and the Bahamas.

We provide quality installation of our products

Flexstone provides a virtually indestructible surface with a
long-lasting durable membrane that provides a waterproof walking surface.

We take pride in providing a quality product on time.

We endeavor to place a signature on all our projects by consistently meeting the requirements of the specifications and by delivering sustainable projects.


We take pride in providing a quality product on time. Flexstone products come in a variety of colours, require minimal maintenance, and may require sealing every 8-12yrs depending on the traffic.


FS Coatings has been installing waterproof membranes since 2012 with over a million square feet of Flexstone installed. Flexstone is the only cold-applied seamless waterproof surface with CCMC approval for roof membranes.


Flexstone is a long-lasting product that meets the requirements of a roof membrane while being an attractive surface that is walkable and can be driven on, making it a great garage and driveway coating.
