Precast pieces of concrete used mainly for civil work. They are made of extra hard double layer and concrete cores with a resistance to compression superior to 35 N/mm, available in several formats to be adapted to the different needs of work.

Elaborated in conformity with UNE EN 1340:2004, they possess the European compulsory guarantee of safety (CE). The whole range belongs to the same resistant family, with a typical resistance to flexure of 6N/mm advisable for conditions of intensive usage (for instance roads or motorways).
