They are blocks with a maximum drilling% of 55%, Limited by the current regulations (DM 17/09/05). They can be used for the construction of multi-storey buildings also in seismic zone, and therefore they are able to sustain, prior to specific structural verifications, the own weight, the ceilings, the overloads, the wind, the seismic forces.

They can be made in two finishes in the face and plaster and with two different mixes: "clay" and "cement". The blocks in "clay" are used light aggregates of expanded clay, in order to reduce the weight of the block and to improve thermal performance and fire Resistance. The blocks in "concrete" are characterised by high masses and better mechanical and acoustic performances.
