AIRPLAST

AIRPLAST is a modular formwork used to create voided monodirectional slabs. It is made of recycled polypropylene, and can be cut quickly and easily to make offsets.    AIRPLAST formwork can easily be combined with prefabricated slabs. The elements are placed over the fresh concrete and then moved to the construction site ready to be installed.    Learn more Airplast Slabs solutions Airplast VS Polystyrene Antica Corte, Lecco, Italy EDF Research centre, Saclay, France   More

NEW NAUTILUS

New Nautilus is a modular formwork made of recycled polypropylene, designed to lighten reinforced bidirectional concrete slabs poured on-site. It is used as single or double element, increasing the depth of slab when necessary. All our slab formworks are easy to use, transport, and stack, and make the buildings more resilient and sustainable. We have also designed calculators for slabs dimensioning, which help engineers to take real slab thicknesses in the early phases of the design process.SOLUTIONSBidirectional slabs for parking lotsSlabs for hospitalsSlabs for school buildingsPrefabricated predalles slabsDisposable formwork for lightweight foundation slabsBidirectional slabs for residential buildingsLEARN MORENew NautilusNew Nautilus sla...
