Kerbs and plinths

Porphyry: an ideal material for kerbs and plinths

Porphyry is a particular type of volcanic rock belonging to the "Atesina Porphyry Platform", an enormous complex of volcanic rocks that extends into the Trentino-Alto Adige region. These rocks, extremely varied and differentiated, both as a chemical composition and as a form of formation, are the result of an intense volcanic activity started 260 million years ago in the Permian period, and continued for several million years with a continuous repetition of eruptive phases and stasis phases. Among the various methods of deposition of these rocks, the so-called ignimbrites take on particular importance, as these are the ones that gave rise to the "porphyry". These are flows of liquid-gaseous mixtures with thicknesses generally ranging from 5 to 20 meters and with a fairly constant chemism, up to the so-called ignimbritic unit, which reaches hundreds of meters thick.

Kerbs and plinths of various sizes

The retaining walls made of porphyry ashlar (exposed face) are perfectly pleasing and perfectly set with the natural landscape, erasing the unpleasant appearance of the concrete walls.
The porphyry plinths are produced with a height of 10- 15 cm, 12-20 cm and 15-25 cm, with variable length, their shape is reminiscent of a parallelepiped. The warm color with various shades, fits in admirably with any architecture; they are very suitable for supporting walls of roads, embankments etc. Very interesting is the production of veneered facades with recess not higher than 15 cm; it allows the coating of concrete walls, building blocks, pillars etc.
The porphyry kerbs constitute the embroidery thread that designers use to design squares, floors in general or to shape flower beds, pedestrian areas and gardens.
