When tile meets water in a shower, wet room or below-grade space, the membrane underneath decides whether the assembly stays dry. Oshawa Concrete installs Laticrete Hydro Ban and 9235 waterproofing systems paired with matched underlayments, all specified and installed as one integrated concrete and tile assembly.

The layer that matters most
Why Waterproofing Membranes Fail (and How Laticrete Prevents It)
Tile and stone look solid, but water finds every seam. The real protection sits underneath, in the membrane that stops moisture before it reaches the substrate. Laticrete waterproofing (Hydro Ban liquid, 9235 fabric-reinforced) is engineered to bond chemically to the substrate below and the thinset above, so water cannot migrate around the edges.
Most failures happen at layer boundaries, where incompatible products meet and adhesion fails. By choosing Laticrete underlayments, primer, membrane and thinset from the same manufacturer, you eliminate that weak point. The concrete slab gets flat, the membrane bonds to it, and the tile bonds to the membrane.
We evaluate the concrete slab, the wet-area geometry, and movement patterns 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 the substrate, bringing it flat and creating a sound base for the waterproofing membrane to bond to.
Apply the membrane at full thickness
The waterproofing membrane is rolled or sprayed to the manufacturer-specified thickness, with all seams, corners and penetrations detailed and sealed.
Set tile into Laticrete thinset
Tile or stone is embedded in a Laticrete thinset mortar that bonds into the membrane, creating one continuous waterproof assembly from slab to grout line.
Two products, one system
Hydro Ban vs. 9235 Fabric-Reinforced
Hydro Ban is a liquid-applied membrane that flows into corners and seals flat surfaces in showers, wet rooms and below-grade tile work. It cures to a flexible, waterproof skin that tile sets directly into.
The 9235 system adds a reinforcing fabric at corners, movement joints and complex transitions where liquid alone cannot handle the stress. We specify 9235 when the geometry demands extra durability or when the slab is prone to movement.
Hydro Ban, 9235, underlayments and tile assembly details in Oshawa.
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.
