New technology for fragile stone blocks
Since its foundation in 1975, Savema S.p.A. of Pietrasanta, Italy, has developed into a leading stone producer in the international marketplace, and it has introduced a number of stoneworking innovations over the past three decades. One of the latest has been the implementation of a system that utilizes vacuum technology and pressure to impregnate fragile stone blocks with epoxy resin reinforcement.
The system from Errebi uses technology developed between a collaboration of Protec - which makes a range of equipment for resin treatment - and Savema. The entire block runs on a conveyor into a specialized chamber, and a combination of first vacuum treatment and then pressure is used for optimum penetration of the resin.
By utilizing this process, Savema is able to take a fragile, brittle stone and make it structurally sound, and this process offers several advantages. The most obvious is the ability to create slabs out of materials that were previously considered to be too fragile for effectively processing into slabs. And from a practical standpoint, when blocks are processed using the system, they do not have to be squared prior to sawing. Moreover, the resin-treated blocks offer a safer work environment during the sawing process, and the finished slabs are more consistent.
