This building System with “semi pre-cast” elements; it is the combination of on-site concrete casting and a system of prefabricated elements. The pre-cast elements are concrete slabs reinforced with latticework and electro-soldered mesh. This system includes singe-layer and double-layer slabs.

The semi pre-cast product is assembled at the building site perfectly coupled, so forming a continuous slab or wall. The collaborating reinforcements are positioned and a concrete casting finalizes the process. After curing, the result will be a monolithic construction.

This production process simply makes needless the use of supporting formwork systems and the preparation of

complex reinforcement sets at the building site, while considerably reducing construction costs and time of each building. This system assures perfectly smooth casting surfaces.
