EVG 3D Concrete System
Description
The EVG-3D Concrete System is based on panels of expanded polystyrene (EPS) insulation and steel reinforcement which are site-applied with concrete. The system is suitable for the walls and floors of housing and commercial buildings.
The EVG-3D panels consist of a layer of mesh on either side of an EPS core, welded together by steel diagonals (trusses) which penetrate through the EPS core. The panels are joined in the desired configuration on site and sprayed both sides with concrete to form a sandwich type construction. The exterior of the panels are finished with a weatherproof coating such as plaster, while the interior surfaces (walls and ceilings) can either be plastered or lined with conventional lining materials such as plasterboard.
