Laticrete is the line we install for tile, stone and decorative concrete assemblies where waterproofing and the right underlayment decide whether the finish lasts. Boston Concrete installs Laticrete Hydro Ban and 9235 waterproofing membranes plus the underlayment systems that sit beneath them, all to the published Laticrete spec. Every project starts with a free written estimate.
Most tile and stone failures in wet areas trace back to what is under the tile, not the tile itself. Laticrete waterproofing (Hydro Ban liquid membrane, 9235 fabric-reinforced system) is the layer that keeps a shower or wet floor watertight under daily use.
Under that, Laticrete underlayments get the substrate flat, sound and bonded to the membrane above. Choosing both from the same Laticrete family means the chemistry is engineered to bond layer to layer, instead of stacking incompatible products and hoping.
It is the same install discipline behind our Ardex and Mapei work, and it ties into the wider residential floor systems we install.

How we install
How We Install Laticrete Systems in Boston
Pick the Hydro Ban or 9235 line
We confirm the wet-area use and substrate, then pick between Hydro Ban liquid membrane and the 9235 fabric-reinforced system based on what the application needs.
Set the substrate flat
The substrate is prepared and brought flat with a matched Laticrete underlayment, so the waterproofing membrane goes onto a sound surface ready to bond.
Apply the membrane in full
The waterproofing membrane is applied at the manufactured-specified thickness with seams and corners detailed, then flood-tested where the install requires it.
Tie into the finish above
Tile, stone or finish is set into a Laticrete thinset that bonds into the membrane, so the assembly above and below the membrane is one continuous system.
Two lines, one system
Hydro Ban, 9235 and Underlayments
Hydro Ban is the liquid-applied membrane that turns walls and floors watertight in showers, wet rooms and below-grade applications. The 9235 fabric-reinforced system adds reinforcement where movement or detailing demands more.
Laticrete underlayments sit beneath them, getting the substrate flat and ready, and the same family runs into the Laticrete thinsets and grouts above. It is the same one-system thinking we bring to our Mapei installs.
Hydro Ban vs 9235, waterproofing tile assemblies, and matched underlayments in Boston.
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.
