These porous terracotta blocks are elements characterized by a gross density of about 700-760 or 800-860 kg/m3, suitable for use for the construction of load-bearing walls in any area, including those presenting seismic risk.

These blocks are elements classed as semi-solid, characterized by a gross density of ? ? 45% and ? ? 55%, to be used with the holes in a vertical position, offering values of resistance to breakage that are far superior to the minimums required by building codes.

The semisolid porous blocks are produced in various sizes and thicknesses, and, in connection with different geographical areas, either ?smooth? or ?interlocking?.
