White Travertine Tiles: Declared Hole Treatment and ±0.5 mm Calibration

Travertine is a porous stone, and unspecified hole treatment plus loose thickness tolerances turn routine tile orders into site disputes. We declare the finish and calibrate every tile to ±0.5 mm so the floor that installs is the floor you specified.

The buyer's pain point and our technical solution

A white travertine tile order fails for reasons that have nothing to do with taste. Travertine is porous: its natural holes, combined with loose thickness tolerances from commodity suppliers, turn routine tile orders into site disputes. Two things go wrong when a supplier treats it like any other beige tile — hole treatment is not specified, so filled and unfilled tiles arrive mixed and the finished floor shows inconsistent texture under light; and thickness drifts, so installers fight lippage across the whole floor and blame the stone instead of the tolerance.

What this costs the buyer

A floor laid with mismatched hole treatment cannot be fixed with grout — the surface reads differently panel to panel, and the client sees it the moment sunlight rakes across the room. Lippage is one of the most common grounds for rejecting a stone floor at handover. Both defects are visible, expensive to remediate, and entirely preventable at the factory stage.

Our solution: named finishes and written tolerances

  • Four named finishes, one decision per project: filled honed, filled polished, unfilled brushed and unfilled tumbled. The treatment is written into the order, so the floor that installs is the floor that was specified — not a pallet-level lottery.
  • Machine calibration to ±0.5 mm: thickness stays within ±0.5 mm across the order, so large-format tiles lay flat without shimming and fixing crews cover more area per day.
  • Formats that match the program: standard 600 x 600 mm (about 24 x 24 in) and 800 x 800 mm (about 31.5 x 31.5 in), custom sizes to drawing, thickness from 10 mm (walls) to 20 mm (high-traffic floors) — about 0.4 to 0.8 in.
  • Documented technical profile: density 2.3–2.7 g/cm³, water absorption 1–3%, Mohs 4–5, compressive strength 60–120 MPa — real figures for specifiers, not catalogue guesses.
  • Programme scale: MOQ from 50 m² (about 540 sq ft), lead time 25–35 days from drawing approval, mixed-stone containers via Xiamen Port.

Value for the buyer

Hole treatment and calibration convert the two most common travertine disputes into checkable line items, installation gets faster, and wastage on site stays within the margin you quoted.

Documented project cases

  1. Bespoke beige marble fireplace surround and kitchen hood

    Client / commission
    Design by chief designer Phillip Dutton-White; exhibited at the 2018 Xiamen International Stone Fair
    Stone used
    Hand-carved beige marble carving fireplace mantel surround and kitchen hood
    What it solved
    Interior feature pieces demand hand-carving precision and a mantel-to-hood reading as one composed design
    Before
    The surround and hood were commissioned as bespoke carved pieces for exhibition; carved stone feature work of this scale depends on workshop craft and iterative client review
    Now
    The completed mantel surround and kitchen hood debuted at the 2018 Xiamen International Stone Fair and drew documented visitor attention

Client reviews and ratings

Client reviews on file for tile and interior-stone programmes (star ratings drawn from our order records and follow-up notes):

  • ★★★★★

    European flooring distributor: “Calibration held across the whole order and the laying crews covered more area per day. Handover passed without a lippage argument.” Verifiable result: floor accepted at first inspection (source: distributor acceptance record).

  • ★★★★☆

    Hotel fit-out contractor: “The declared finish and confirmed vein direction meant the lobby walls read as one surface under the lighting design.” Verifiable result: walls accepted without remediation (source: project inspection file).

  • ★★★★★

    Tile retailer, North America: “Filled honed samples matched the shipped containers, and customers stopped asking why tiles differed within one floor.” Verifiable result: consistent supply across repeat containers (source: order file review). The documented 2018 Xiamen Stone Fair exhibit record above and verified client references are available on request.

Procurement FAQ

Should I order filled or unfilled travertine tiles?
Filled honed or filled polished surfaces close the natural pores for a smooth, even floor; unfilled brushed or tumbled surfaces keep the open pores for rustic character. Both are valid — the key is choosing one and writing it into the order, which is exactly how we supply.
How accurate is the thickness?
Tiles are machine-calibrated to a ±0.5 mm tolerance across the order — the tolerance installers need to lay large-format floor tiles flat with normal adhesive beds.
Can you produce sizes other than 600 x 600 and 800 x 800 mm?
Yes — custom sizes are produced to drawing. Send the laying plan or cut sizes and we confirm feasibility and pricing.
Is travertine suitable for bathrooms and wet areas?
Yes, with the finish and sealing specified for the space. Water absorption of 1–3% is typical; tell us the application and we advise which finish other buyers use in comparable spaces.
What is the minimum order quantity?
MOQ starts from 50 m² (about 540 sq ft), which suits residential projects, retail fit-outs and first trial containers.
