Tile and Stone Flooring in Fort Worth, TX

A tile floor is only as stable as what it is bonded to. That sentence covers most of what goes wrong with tile, and in this county it has a specific local meaning. Where the choice is still open, tile vs vinyl plank compares the two on the grounds that actually matter here, and the best waterproof flooring covers wet rooms specifically.

The clay problem, and what actually solves it

East and south of downtown Fort Worth — through Arlington, Mansfield, Crowley, Burleson — the Eagle Ford and Woodbine clays are strongly expansive. They swell when wet and shrink when dry, and slabs riding on them move seasonally. That movement is usually small and usually cosmetic as far as the structure is concerned.

It is not cosmetic to a tile floor rigidly bonded on top of it. A tile bed mortared straight to a moving slab becomes structurally part of that slab, and the movement comes out somewhere: first as cracked grout, then as cracked tile, usually along a line that runs the length of the room.

An uncoupling membrane sits between the two and absorbs that in-plane movement. On the clay side of the county we specify it as standard rather than as an upgrade. On the prairie side — Benbrook, Aledo, Saginaw, west of the Trinity, where slabs sit on shallow soil over Goodland and Walnut limestone and barely move — it becomes a judgement call.

What a membrane cannot fix is active differential movement: a slab that is not just expanding and contracting but genuinely settling unevenly. Telling those two apart before tiling is most of the skill in quoting this work, and the answer sometimes is that the floor is not ready for tile yet.

Large format needs a flatter floor than you think

Published tolerance for large-format tile is around an eighth of an inch over ten feet — roughly twice as flat as a floating floor requires. Large tile is rigid and cannot follow a curve, so a deviation the eye would never notice on a bare slab becomes visible lippage between two adjacent edges.

Large format is what nearly everyone wants. On an older Tarrant County slab it almost always means a self-levelling pour first. That cost belongs in the original quote rather than arriving as a change order in week two, and a bid that does not mention it is a bid that has not measured.

Coverage, checked rather than assumed

Mortar coverage under the tile should reach around 80 percent in a residential floor and 95 percent in a wet area or a commercial one. Voids under a tile are where cracks start, because an unsupported area flexes.

The only way to know is to pull a tile during the set and look. We do that as the field goes down rather than trusting the trowel notch and hoping.

What stone asks of the owner

Travertine, marble, limestone and slate look superb and ask more of the owner than porcelain does. All of them are porous to some degree, all of them need a penetrating sealer, and the sealer needs renewing on a schedule for as long as you have the floor.

Travertine in particular reads beautifully in the Hill Country-facing builds out west toward Aledo and Weatherford. It also has natural voids that get filled at the factory and can open up under traffic. None of that makes it a bad choice; it makes it a choice that needs a maintenance conversation at the estimate rather than a surprise two years in.

Some stone is also unsuitable over radiant heat, which matters if that is in the plan.

Wet areas

Showers and bathroom floors get a proper waterproofing system — sheet or liquid-applied — and it stays within one manufacturer’s stack from membrane through to mortar. Mixing brands across a waterproofing assembly voids most system warranties, and the system warranty is the entire reason to specify one.

Movement joints

Perimeter joints at every wall, and field joints at the intervals the TCNA handbook specifies for the size of the installation. They are designed in at layout stage. Discovering afterwards that a 40 foot run of tile has no movement joint in it is discovering why it cracked.
