The open-concept floor plans common in Chatham Park developments create a natural design opportunity: large-format tile running continuously from the kitchen through the dining area into the living space, with no visual break, creating a seamless interior landscape. It's a beautiful look — but it demands precision installation that a lot of general contractors aren't set up for.
Why Large-Format Tile Demands More From the Installer
A 24"×48" or 32"×32" tile is unforgiving of any subfloor imperfection. Even a 1/8" low spot under a large tile creates a "lippage" — a visible edge-to-edge height difference across a grout joint that you feel underfoot and notice every time light rakes across the floor. When a 12"×12" tile bridges that low spot, the effect is less pronounced; when a 24"×48" tile does, one edge sits on the high side of the subfloor while the other side drops. The tile cracks or lippage appears at the joint.
We use self-leveling underlayment and a laser level referenced to a single datum point to flatten the slab to within 1/8" over 10 feet before any tile is set. On new Chatham Park slab construction this typically takes half a day; on older Chatham County slabs it can take longer but is always required.
Grout Joint Width — The Decision That Changes Everything
The contemporary standard for rectified large-format tile is a 1/16"–1/8" grout joint. This tight joint is what creates the near-seamless stone-floor appearance that defines the look. A wider joint immediately reads as "someone was less than precise" and breaks the aesthetic spell. Achieving 1/16" joints consistently across a 600 sq ft open plan requires tile spacers, a laser layout line for every course, and a slow, methodical pace — about 100–150 sq ft per day for a two-person crew doing it correctly.
Thermal Expansion Consideration for Pittsboro's Slab Construction
Concrete slabs in Chatham County experience meaningful thermal movement seasonally — more than many homeowners expect. We specify an uncoupling membrane (Schluter DITRA or equivalent) between the slab and the tile setting bed on any large-format installation over 300 sq ft. The membrane decouples the tile from the slab's movement, preventing cracking at the grout joints as the seasons change. This is an add cost of roughly $1.50/sqft that we'll always recommend for a long-term Pittsboro installation.
