The Quadra® system is composed of a module of reinforced concrete with polypropelyne fibre and stainless steel fittings for assembly and/or support. You simply screw the sheet metal to the modular slab using the fittings provided. You then place it on the antivibratory blocks and level it. The antivibratory surface can be extended by adding modules using the same system. The tools required are a spanner and a spirit level. The individual support system can be replaced by continuous antivibratory material, in this way a single floating floor is created, essential in situations involving noise by impact in an interior space.
