Sizes and formats

What we hold, in our own warehouse

A format is a decision about logistics before it is a decision about looks. This is what we hold, and this is what the wider trade carries.

What we hold, in our own warehouse

This material is held as slab, in three thicknesses, at sizes that are not one number but a band in two directions. A cut list is checked against the physical stock before it is priced, because a slab size is a band and not a fixed figure.

The 3,000 m² is a surface measure. How many slabs that represents depends on the dimensions of the pieces, so we do not quote a slab count against it.

Nominal weight per square metre, at the published 2710 kg/m³ apparent density: 40.65 kg at 15 mm, 48.78 kg at 18 mm, 54.20 kg at 20 mm. Calibration takes 1-2 mm off the nominal thickness, so a weighed slab reads slightly below the calculated figure.

In the wider trade

Published trade references for the same material: 20 mm 2200-2600 × 1300-1600 mm, 30 mm 2200-3200 × 1300-1680 mm, and one alternative band of 1600-2800 × 1200-2400 mm across 18-30 mm.

800×800 · 600×600 · 300×300 · 300×600 mm as the current module references, alongside the older 10 mm and 20 mm modular formats.

Our standard stock is 15, 18 and 20 mm. In the wider trade the current references are 18, 20 and 30 mm, and after vacuum resin treatment a slab can be cut to 10 mm.

What this stone asks of you

A heavily brecciated structure. The stone can be brittle along the white calcite fault lines, so edge profiling needs care at the corners, and slabs normally arrive resin-backed.
The block carries naturally formed cracks. If they are not repaired during processing, the finished piece is imperfect - so the question of whether a crack can be avoided has to be asked before the size is fixed.
Within one block the slabs differ from each other in colour distribution and in the movement of the grain. Two blocks do not carry the same yellow. Slab grouping is a decision, not an afterthought.
Calcite 95-98%. The stone is acid-sensitive: food, drinks and cleaners etch it and dull it. A penetrating sealer reduces absorption and does not make it acid-proof.
Traditionally an indoor stone. The visible fracture structure is the reason it does not belong in a heavily trafficked exterior position.

Tell us the application, the size and the finish you need, and we will come back with what we can actually supply.

There is no checkout here and there is no price list. A stone enquiry is an agreement about material, size, finish and destination, and the answer depends on those four things. Send them and the reply carries what can actually be shipped.
