RMAX developed the VoidForm® System for waffle raft slab foundations to reduce concrete quantities, provide greater slab strength, increase energy efficiency and save costs and time for the builder.
The VoidForm® System provides speed and ease of use, reliability and improved slab quality together with lower costs. As the RMAX VoidForm® arrive on site ready to use, labour costs are reduced to a minimum. It enables maximum control of every concrete pour.
Made from expanded polystyrene (EPS) the VoidForm® System is unaffected by moisture. So no time is lost using them in wet weather and quality is maintained. They do not sag or buckle even in the most adverse of weather conditions.
The RMAX VoidForm® System was specifically designed to save the builder time and materials. It requires less preparation work and concrete usage is significantly reduced.
The RMAX Void-Lock® grid spacer system speeds up preparation of the slab and holds the voids in place during concrete pouring.
The system can be effectively used on sites of sand, rock, reactive soils and water tables. Quality and standards of the job are assured. Beam excavation is eliminated and the voids are capable of spanning sewers and water mains without piers.
The RMAX VoidForm® system improves the energy efficiency of houses. Its insulation features reduce energy costs, keeping your home cooler in summer and warmer in winter.
