Permaform is a permanent wall formwork system that provides significant savings in cost and time compared to traditional brick or concrete walls.
It is a stable product that can be put together and concrete filled in one day, and does not require bracing.
Made from PVC, Permaform is so lightweight there is no need for cranes or other lifting equipment for installation. The ease of use results in a reduction of safety risks and the associated costs.
Permaform can replace nearly all types of vertical formwork used for walls and columns, and is ideal for multi-storey developments, including apartment complexes and hotels.
Permaform is made in standard wall thicknesses of 110, 150 and 200 mm to a panel width of 400 mm, but can also be made to measure.
Permaform has no need for control joints, as it includes internal diaphragms to act as crack initiators. These produce fine cracks at close centres which are invisible and makes Permaform particularly popular amongst medium to high-density residential builders.
Additionally Permaform forms a permanent shell comprising face sheets connected though closely spaced internal diaphrams which are interlocked to resist concrete filling pressures.
A paint render or other materials can be easily applied to achieve decorative finishes. It is also impermeable to moisture and has the ability to be a totally waterproof solution system.
Developed by Robert Rech and Peter Zardo in 2013, Permaform is sold in Australia through Big River Group.
