Pre-mixed self-levelling screeds and substrates
The OVERMAT A-series system is a screed mixer enables lightweight subfloors to be poured. With no hassle and total precision.
The Overmat range includes different types of systems, to satisfy the customer’s needs.
The variables may concern the mixing of the dough: from the single mixing tank system to the double mixing system, so as to be able to increase both the hourly production and the quality of the final product.
Completely automated, thanks to their versatility they allow the operator to produce lightened substrates in all its variables, from a 100% foam product to a polystyrene-only product, as well as a mixed product. All of which can be controlled automatically and with dosages of the various certifiable components.
The features present in the 22 A PTO system (or 13.9 A PTO based on the chosen configuration) are important. The only system on the market capable of producing both a lightweight product (foam and polystyrene) and a pre-mixed self-levelling screed, even on the same day, loading two different binders into the two independent compartments.
The entire process is recorded in the system computer and can also be viewed on the internet, using a special data SIM installed on the machine.
The lightweight substrate is used as an intermediate level between the floor and the screed. It is made using a cement binder dosed at 250-350 kg/m3, a foam (obtained using a surfactant additive) and can possibly be integrated with a low specific weight insulator (polystyrene, perlite, rubber, cork, etc.)
