The plant

The plant sits between Adriakamen and Plano Lithos, so a block travels less than a kilometre from the bench to the gang saw. We saw, calibrate, cut to size and finish all the stone from our three quarries here.

The block never changes hands

From the bench to your building the stone never changes hands. For every delivery we know which block it came from and which bench.

If a facade has to hold one tone from the ground floor to the roof, we cut its panels from one block, or from neighbouring blocks off the same bench.

The line a block runs

The machines in the order a block goes through them.

Gang saws and single-blade block saws
The first cut. A block goes in whole and comes out as a stack of full-size slabs. The gang saw takes the whole block at once. We use the single-blade saw to square a block, or when you need a thicker piece.
Calibrating machine
SIMEC
Brings every slab to the same thickness across the whole face. Without it you would feel an uneven floor underfoot before you saw it, and cladding would never sit evenly on its adhesive.
Bridge saws
Bombieri & Venturi, GMM, Tagliablocchi
This is where your drawing gets cut: tread by tread, sill by sill. It is the machine in the film at the top of the page.
Edge polisher
Finishes the edge along its full length in one pass. On a tread, a sill or a coping, the edge is the part people see and touch most.
Profiling machine
Ghines
For anything that is not a flat slab: bullnoses, grooves, cornices, sills with a drip groove and pool edges.

What leaves the plant

Stone leaves the plant in four forms. If you need any of them, we make it here at Plano.

Blocks
Stone as it comes off the bench, cut out with diamond wire and squared up. We also sell them unsawn, by the cubic metre.
Gang-sawn slabs
The block reduced to full-size slabs, in the thickness the project asks for. They stay in sawing sequence, so the figure of the stone runs on from slab to slab.
Cut-to-size elements
Facade panels, floors, treads and risers, sills, pool and wall copings, thresholds and profiles, cut to the drawing and marked by position.
Setts and pitched-face stone
Paving for public ground, setts, split stone for dry-stone walling and pitched-face walling blocks, and technical stone for embankments and sea walls.

One face, six treatments

Smooth finishes go indoors, textured ones outside and anywhere that gets wet. Most of the finishes on our list take two passes, and the second is usually brushing, so the surface grips underfoot without scratching the hand.

Honing
A flat, matt face with no shine. The usual finish for interior floors.
Polishing
A mirror shine, and the stone takes on the colour it has when wet.
Brushing
Abrasive brushes take the softer grain down before the harder, leaving a low relief with a satin feel. Also called antique finish.
Sandblasting
A finely textured, even face that stays safe underfoot in the rain.
Bush-hammering
A toothed bush hammer pits the whole face. The roughest finish, and the one that lightens the stone most.
Combined passes
Sandblasted then brushed, bush-hammered then brushed, coarse bush-hammered then brushed. Brushing takes the edge off the first pass, so the face grips underfoot without being harsh to the hand. Most of the nine finishes listed for each stone come from these.

When an element is not a flat slab

We make volutes, cornices, arches and solid pieces here, alongside the floor slabs. For ventilated facades we kerf and drill the panels for anchors to the drawing and number every piece by position.

Where it stands

Put Karanušića 73, Plano. Adriakamen and Plano Lithos are a few hundred metres away, and Dalmalit, where Dolit comes from, is about fifty kilometres towards Omiš. You are welcome to come and see the slabs before you order, and for a large surface we recommend it.
