Also, its hollow structure allows pipes, ducts and cables to be positioned in every direction. Granchio is equipped with an interlocking connection system which makes it fast and easy to lay. The useful load varies depending on the capacity of the ground, the underlying lean concrete and the thickness of the slab. Granchio, being a disposable formwork, is designed to support the weight of the operators and the concrete during casting. In accordance with the recommendation of the Commission of the European Communities of 02/21/90, due to the positioning of special ventilation holes, crawl spaces made with the Granchio formwork benefit from good ventilation moreover, humidity is eliminated, and radon gas is dispersed.
Granchio is a disposable formwork in recycled polypropylene which is used, as an alternative to traditional systems, for the construction of ventilated crawl spaces in both new constructions and renovation projects.
