We rely on the different experts of the Network to respond, namely Dr. Pons from San Salvador who is busy tutoring students (and professors) all over Latin America on adobe construction.

Microconcrete technologies used in hotel in the Dominican Republic
A builder and hotel owner from the Dominican Republic bought a tevi equipment two years ago. His interest was not only tiles, but specifically to produce vaulted formwork for concrete slabs, an application he had seen in a hotel built by EcoTec in Nicaragua. Concrete beams are prefabricated on site, and after fixing them in position the 12mm thick tevi-vaults are placed as formwork, and provide an attractive finish. He is now using both applications of vibrated micro concrete in the construction of a new hotel in Constanza.
