Double Wall consists two parallel prefabricated concrete panels with a 5 to 7 cm width between, connected with cage beams. Concrete coverings already have static reinforcement.
Double Walls are manufactured in factory, delivered and assembled at site, and concrete is poured beneath them to make a solid finishing. This provides a monolithic total section.
The advantage of double wall is leaving no need for mold work at site. Extremely short construction time and a very clear surface is the outcome.
