Sintered Stone Slabs in Indonesia

Slabs are the unit that matters: the format decides how many joints a wall carries, and the pattern decides whether a bookmatch pair works across a joint. Both are easier to judge standing in front of the material.

Formats

900 × 2700 mm, 1200 × 2700 mm, 1200 × 2400 mm and 1600 × 3200 mm. The largest format covers 5.12 m² per slab, which is what allows a full-height wall to be covered with very few joints, or a long island to run without a break.

Large format sintered stone in Indonesia means formats up to 1600 × 3200 mm, which is what allows a wall to be covered with very few joints.

Thickness

6 mm for wall panels and furniture fronts, 9 mm for interior surfaces, 12 mm and 15 mm for countertops and table tops, 20 mm for heavier duty in 1220 × 2700 mm. Thickness follows the application, not the pattern: choosing a pattern first often leads to a slab that cannot be used where it was intended.

Finishes

Bright, matte, bookmatch and ABC, plus translucent options for backlit work. Matte hides water marking and reads calmer in small rooms; bright reflects light and suits darker interiors. Bookmatch pairs are matched from production so veining mirrors across the joint, with a 1 cm joint tolerance agreed at sample stage.

Large-format slabs and handling

A 1600 × 3200 slab is heavy and awkward rather than simply heavy. It needs a lifting frame, a protected route and space to tilt, and the access is checked before dispatch: a slab that cannot enter the building is a problem discovered too late. This is why the site visit or a video call happens before the cutting plan is finalised.

Inspecting slabs before purchase

Slabs are inspected at the gallery in Kapuk, Jakarta Barat, or reviewed by video for buyers outside Jakarta. The specific slab, not a sample of the series, is what gets approved before fabrication.
