Showers, wet rooms and tile floors need a waterproofing layer that bonds to the substrate and the finish above. We install Laticrete Hydro Ban and 9235 systems with matched underlayments, all specified and installed as one integrated assembly. Call for a free written estimate.

The layer that matters
Why Waterproofing Membranes Stop Tile Failure
Tile and stone look good until water finds its way behind them. The membrane is what stops that. Laticrete waterproofing (Hydro Ban for liquid application, 9235 for reinforced detail work) sits between the substrate and the tile, turning a porous surface into a watertight barrier.
Below the membrane, Laticrete underlayments flatten the substrate and create a chemical bond with the membrane above. This one-brand approach eliminates the weak point that happens when you mix products from different manufacturers.
The same system thinking guides our work with Sika and BASF products, ensuring every layer works together instead of against each other.

Installation sequence
How Laticrete Waterproofing Gets Installed
Assess the substrate and use case
We evaluate the surface, the wet-area exposure and the tile type to decide between Hydro Ban liquid membrane and the 9235 fabric-reinforced system.
Prepare and level with underlayment
A matched Laticrete underlayment is applied to bring the substrate flat and create a stable base for the waterproofing membrane.
Apply the membrane at full thickness
Hydro Ban or 9235 is applied per manufacturer spec, with special attention to corners, seams and transitions where water pressure is highest.
Set tile into Laticrete thinset
Tile or stone is embedded in a Laticrete thinset that chemically bonds to the membrane, creating one continuous waterproof assembly from substrate to finish.
Two products, one approach
Choosing Between Hydro Ban and 9235
Hydro Ban is a liquid-applied membrane that flows onto walls and floors, sealing the substrate in one continuous layer. It works for most shower and wet-room applications where the surface is relatively flat and movement is minimal.
The 9235 fabric-reinforced system adds a woven reinforcement layer, giving extra strength at corners, movement joints and complex transitions. We choose based on the specific assembly and the stresses it will face. Both systems use Laticrete thinsets and grouts above, keeping the whole assembly in one product family.
Hydro Ban vs 9235, tile assembly waterproofing, and underlayment selection in Gatineau.
Hydro Ban is a liquid-applied waterproofing membrane for showers, wet rooms and below-grade tile assemblies. It seals the substrate, then tile or finish sets into a Laticrete thinset that bonds into the membrane.
The 9235 fabric-reinforced system adds reinforcement at corners, movement joints and detailed transitions where liquid alone is not enough. We pick based on the specific assembly.
Usually yes. A matched Laticrete underlayment brings the substrate flat and bonds chemically to the membrane above, removing the layer-boundary failure mode you get from mixing brands.
Yes. Hydro Ban and 9235 are designed for shower assemblies and are widely specified for wet rooms, with proper detailing at drains, corners and curbs as part of the install.
We install Laticrete systems to the published manufacturer spec, with primer, membrane and tile-setting products from the same family, so the warranty is intact and the assembly performs.
A shower that needs waterproofing, a wet-room floor, or a tile assembly that has to last decades, tell us the scope and we will spec the right Laticrete system and send a written quote.
