CUPOLEX® is a patented technology from Pontarolo Engineering spa for the construction of aerated floors, raised slabs, and lightweight fill replacement, it is a fast and economic system to cerate the sanitary void. One of the principal advantages of CUPOLEX® system is the healthiness of the building, due to the good air circulation, gas removal e.g. Radon gas, and humidity elimination. The igloo shaped elements, once placed and connected together are able to receive the concrete cast giving the slab a unique geometry with a matrix of small columns 56 cm distant ( 71 for domes heights above 55 cm), a hollowed space underneath and a slab thickness that can be designed to hold and load. The accessory element BETON STOP is used to close the lateral apertures, to prevent the concrete cast to enter the hollowed space, and can also be adjusted to fit any plant design with no need to cut the CUPOLEX® elements. The system also permits the monolithic cast of foundations and aerated slab.
