When tile meets water in a Pittsburgh bathroom or wet room, the membrane underneath decides whether the assembly stays dry for decades or fails in years. We install Laticrete Hydro Ban and 9235 waterproofing with matched underlayments, all specified and installed as one integrated system. Free written estimate on every project.

The substrate matters most
Why Laticrete Waterproofing Stops Leaks
Tile and stone failures in wet areas rarely start at the tile. They start below, where water finds its way through a substrate that was not sealed, not flat, or not bonded to the layers above and below. Laticrete waterproofing (Hydro Ban liquid, 9235 reinforced) is the barrier that keeps water out of the concrete or substrate beneath.
The underlayment layer sits under the membrane and does two jobs: it brings the substrate flat and sound, and it bonds chemically to the waterproofing above. When you use Laticrete underlayment with Laticrete membrane, the chemistry is matched. You avoid the layer-separation failures that happen when contractors mix brands.
We evaluate the substrate condition, the wet-area application (shower, wet room, below-grade), and any movement or detailing challenges to decide between Hydro Ban liquid and 9235 fabric-reinforced.
Prepare and level with underlayment
The substrate is cleaned and prepped, then a matched Laticrete underlayment is applied to bring the surface flat and create a sound base for the waterproofing membrane.
Apply the membrane at full thickness
Hydro Ban or 9235 is applied to the manufacturer-specified thickness, with all seams, corners and transitions detailed and sealed. Flood testing is performed where the assembly requires it.
Set tile into Laticrete thinset
Tile or stone is set into a Laticrete thinset mortar that bonds into the membrane below, creating one continuous waterproofed assembly from substrate to finish.
Two products, one system
Hydro Ban Liquid vs 9235 Fabric-Reinforced
Hydro Ban is the liquid-applied membrane that seals walls and floors in standard showers, wet rooms and below-grade tile applications. It flows into corners and seams, creating a continuous waterproof layer that tile or stone sets directly into.
The 9235 fabric-reinforced system adds a woven fabric layer for extra durability at movement joints, inside corners, and complex transitions where liquid alone cannot handle the stress. Laticrete underlayments work with both, and the thinset and grout complete the system. It is the same integrated approach we use with Mapei products.
Hydro Ban vs 9235, tile assembly waterproofing, and matched underlayments in Pittsburgh.
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 stay dry, tell us the scope and we will spec the right Laticrete system and send a written quote.
