A tile shower is only as good as its waterproofing system underneath. We install industry-leading membrane systems including Schluter Kerdi, RedGard, and foam-core shower systems before any tile goes down, protecting the structure for decades.
After framing or cement board installation, the waterproofing membrane is applied over all surfaces, floor, walls, and transitions. Seams and corners are taped and sealed. Schluter Kerdi or similar systems are used for full-coverage protection.

Frequently Asked Questions
Why does a shower need a waterproofing membrane if there is already cement board?
Cement board is moisture-resistant but not waterproof. Water penetrates it over time and will eventually reach the framing and subfloor, causing rot, mold, and structural damage. The waterproofing membrane - applied over the cement board or foam substrate - is what actually stops water. Without it, even a well-tiled shower will fail within years.
What is Schluter Kerdi and why is it recommended?
Schluter Kerdi is a bonded waterproofing membrane system that installs directly over drywall or cement board. It's thin, fabric-reinforced, and tiles bond directly to it using modified thin-set. It's popular because it eliminates the need for heavy mud beds, installs faster, and has an extensive system of matching drains, corners, and transitions that create a fully integrated waterproof assembly.
How long do we need to wait after waterproofing before tiling?
With Schluter Kerdi, you can typically tile the next day once the thin-set bonding it has cured. Liquid-applied membranes like RedGard need to cure to a solid colour - usually 24-48 hours depending on temperature and humidity. We won't rush this step because it's the most critical part of any shower installation.
How long does a properly installed waterproofing system last?
A properly installed membrane system in a residential shower should outlast the tile itself - typically 20-30 years or more. Failures usually come from poor installation at corners and penetrations, or from grout and caulk maintenance being neglected. We treat every corner and pipe penetration as a potential failure point and detail them accordingly.
