Why Waterproof Membranes Stands Out

Liquid vs. Sheet Waterproofing Membranes

Choose the right membrane for your project. Liquid-applied membranes, like Mapei Mapelastic AquaDefense, create a seamless, flexible layer that conforms to corners and penetrations. Sheet-applied membranes, such as Schluter KERDI, ensure uniform thickness, immediate tiling, and long-term durability.

Dual-Function Membranes: Uncoupling + Waterproofing

Products like Schluter DITRA combine waterproofing with an uncoupling layer, preventing floor cracks from transferring through the tile assembly. Ideal for large-format tiles, heated floors, or concrete subfloors.

Featured Products

Schluter KERDI: Polyethylene sheet membrane acting as a waterproof and vapor barrier. Mapei Mapelastic AquaDefense: Liquid-rubber, flood-testable membrane covering ~100 sq. ft. per 3.78L container.

Still Have Questions?

Quick answers to the questions homeowners ask most before buying.

Do I need a professional to install a waterproofing membrane?
While some liquid systems are DIY-friendly, professional installation is recommended for sheet membranes to ensure proper seam sealing and warranty coverage.
Can a waterproof membrane prevent tile cracking?
Yes, uncoupling membranes accommodate substrate movement, preventing stress from cracking tiles and grout lines.
How much does a typical shower waterproofing project cost for materials?
Materials typically cost between $200 CAD and $1,200 CAD depending on the system chosen (e.g., Laticrete for budget, Schluter for premium).
Where can I buy Schluter and Mapei products locally?
Available at Squarefoot Flooring, with pickup in Mississauga, Toronto, and Barrie.
