Unrivaled Versatility & Durability

Flexstone is an attractive and versatile industrial-strength waterproofing membrane. It is designed to easily withstand heavy abuse from the elements and heavy foot or vehicular traffic. Flexstone is the common-sense answer for sundecks in Canada.

Flexstone’s four-ply CCMC approved rubberized membrane relies on the foundation of it’s solvent-free base coat - which adheres to nearly any substrate (concrete, plywood, fiberglass, vinyl, urethane membranes, torch-on and more) and retains its flexibility indefinitely. The base coat is installed thick with a v-notched trowel or squeegee.

The finish coats are not only aesthetically gorgeous, they have an important job. Our rugged mock-aggregate finishes provide a tough but flexible outer shell that keeps the membrane safe from heavy traffic and UV damage.

Flexstone is Eco-Friendly

Flexstone's base is 100% solvent-free: water catalyzed!
It can be applied safely over existing coatings.

Competing urethane based products can't because their solvents will dissolve the membrane below. This means you can apply Flexstone's waterproofing membrane over old vinyl, fiberglass, or torch-on materials. This also means keeping old roof and deck debris out of our landfills.

The UV stability, and reflective nature of a Flexstone finish saves on energy costs. Your air conditioning can run for a fraction of the time during Summer months, and the seamless insulation properties of our product hold heat in better during the Winter.
