Precast Concrete Panels Using Concrete, Welded Mesh And Plates, Polystyrene Core

� Pre-cast concrete load bearing panels are made of reinforced concrete with a polystyrene insulated core that varies in size from 40mm to 200mm depending upon the insulation requirements.

� The reinforced concrete panels are moulded in specially designed steel moulds under specially designed steel moulds under controlled factory conditions.

� The buildings and houses can be designed to suit any geographical position or environment and can withstand wind speed in excess of 285km/hr.

� The system does not impose any design restrictions Due to cohesive structural design, the system requires only strip foundation for most buildings.

� The system is entirely a “on-site” construction process.

� The houses are entirely, including the roof, made up of structure panels assembled with Beams.

� Alleviated concrete, a special mix of concrete and expanded polystyrene beads, hence incorporating both the thermal and the sound insulation, is injected into a steel structure made of panels reinforced with beams (galvanized steel wire studs / steel rods).

� The Concrete base and the foundations of the houses are prepared in a conventional manner. The panels are tied to the soldered wire mesh and to the iron rods in the base and in the foundations and assembled in accordance with the design of the house.
