Formworks for hollow core plinths
The reusable formworks for hollow core plinths are made of a full block of polystyrene foam cut into a truncated pyramid with sizes as requested by the customer.
A metal plate is inserted inside the formwork in order to facilitate extraction after the casting. At each casting the formwork for hollow core plinths are covered with a polyethylene sheet supplied by the company in order to prevent the concrete from sticking.
Extraction can be carried out after few hours or even after several days with the use of a lever or – better still – with a mechanical device. The polystyrene foam that Arbloc uses for its formworks guarantees both strength and light weight, i.e. the two crucial factors needed in order to work rapidly and save on labor costs.
