Crack isolation membranes that bridge hairline cracks and small movements in concrete so they are less likely to telegraph through new tile.
Concrete cracks, and tile on top of a crack can crack with it. Most hairline cracks are cosmetic, but they can move a little with seasons and settling, and a rigid layer of tile and mortar does not forgive movement. A crack isolation membrane is a thin layer that absorbs some of that movement. Homeowners in Nashville with older slabs in garages, basements and kitchens benefit from this step.
First we look at the crack. Hairline cracks that are stable can be bridged with a sheet or liquid membrane. Wider or offset cracks, where one side is higher than the other, may signal a structural or soil issue, and we recommend a professional's opinion. We clean and fill the crack, then apply the membrane across it and over the surrounding area, as directed by the maker, and set tile on top. We also plan movement joints to follow existing slab joints, because those are designed to move. Take photos of cracks with a coin for scale, and mark any that look wider or uneven. Share whether the slab is old or new, and whether it has had water problems. We use that information to decide which cracks to bridge and which to refer for a closer look.

You tell us the rooms, the tile you like and your timing, and we ask about the floors, walls and any water issues.
We check flatness, moisture and layout from photos or a visit and talk through materials, pattern and trim.
You get a plain written scope with prep, waterproofing, materials, schedule and cure times before anything is ordered.
Old tile comes out, floors are repaired and leveled, backer board and membranes go in and showers are waterproofed and tested.
Tile is set with the right mortar, checked for flatness and alignment and cut carefully at the edges.
We grout, seal and caulk, clean up and walk the finished job with you, leaving written care tips and extra tile.
No. It reduces the chance of hairline cracks telegraphing through tile, but it cannot stop major movement.
Wide or offset cracks need a closer look and perhaps a professional's opinion.
Yes. Joints in tile should follow joints in the slab.
