Airplast is a modular formwork made of recycled polypropylene (PP), developed as an advanced alternative to polystyrene for the lightweighting of precast predalles slabs.
Drawing on Geoplast’s many years of experience in structural lightweighting systems, Airplast is designed to be integrated directly in the precast plant onto fresh concrete, ensuring precision, stability, and production continuity.
The system anchors perfectly to the slab thanks to its support feet and integrated alignment system, ensuring consistent rib geometry and high quality of the finished element.
Made of recycled polypropylene, Airplast does not absorb water, does not release moisture over time, and does not require venting in the event of fire, allowing the slab to achieve the required REI fire-resistance performance.
Lightweight, walkable, and modular, Airplast optimizes production processes, reduces storage costs, and improves the overall reliability of the predalles system.
AIRPLAST formwork is far more resistant than polystyrene and does not break in the corners. Moreover, it is impermeable, thus it does not hold water and does not release it over time.
AIRPLAST formwork does not contain any harmful gas like styrene, thus it does not require any ventilation system, which is otherwise necessary according to VV.FF regulations, when using lightening system in polystyrene because it tends to explode, causing collateral damage, when under pressure.
