Porphyry slabs for uncertain and Palladian work

The porphyry slab, used to make mosaics, Palladian or uncertain work, is made up of natural quarry slabs characterized by different sizes and thicknesses. The visible upper face of the slab has a natural surface, while the edges are irregularly split.

We obtain the best slab by making a first selection of the raw material directly from the quarry; the sorting is done manually by our staff, the slabs are then flaked one by one and carefully stacked on pallets with an approximate weight of about 15 quintals. The latter is the standard size, but we can provide customers with custom-sized pallets based on special needs.

Uncertain or Palladian work: unique flooring

With quality porphyry slabs it is possible to create outdoor flooring in uncertain work, also called mosaic or Palladian (so named in honor of the famous architect Andrea Palladio who used these particular flooring in his refined villas).
These pavements, very common in northern Italy, are obtained by juxtaposing irregular porphyry slabs without a true geometric order, therefore never the same as each other; nevertheless the joint between the slabs, always very regular, restores a sense of elegance and order.

Thanks to our deposits, the customer can choose between the different colors that distinguish the Trentino Porphyry and therefore make each flooring exclusive.

Use and installation of porphyry slabs

Based on the type of porphyry flooring to be built, i.e. pedestrian, cladding or driveway, we provide the customer with material with different thickness.

  • Pedestrian or cladding: thin mosaic with a thickness of 1 / 3.5 cm
  • Drive over: normal mosaic with a thickness of 2/6 cm

The installation on the floor takes place on a concrete screed bound by electro-welded mesh.

To lay the thin 1 / 3.5 porphyry mosaic, approximately 8 cm of thickness between the material and the bedding mortar is required. For the normal 2/6 cm mosaic, about 10 cm thick are recommended; finally, if space permits, it is possible to use the thickness of 2/6 cm also in pedestrian pavements.

During installation, the lower part of each individual porphyry slab is spread with cement grout. This will serve as an adhesion between the porphyry and the bedding mortar.
Once the installation is complete, proceed with the grouting of the joints with cement grout.

Floor maintenance

It is sufficient to clean the porphyry flooring with a hydro-cleaner or water; We do not recommend the use of detergents which, often containing acids and aggressive substances, could compromise the cement seal.
