We received an order to fill the slab with polystyrene concrete in an apartment building. According to the project, the material must have a grade D150, then reinforcement and fiber-cement screed. The facility operates a mini-factory SSM-500-30M1 with an automated system for dosing water and foam. The installation from floor to floor is lifted by a small crane-beam, which we made specifically to carry out work with a load capacity of up to 1 ton.
