LEADING SUPPLIER SINCE 1979
What is it?
Flood Super Voidslab®, our trademark voided slab unit, is Flood Super Wideslab® with attached EPS void formers that allows the slab to span further and reduces the unit self weight.
This product innovation evolved due to the requirement of our customers to achieve greater structural spans whilst reducing the overall building mass and maintaining the benefits of our Flood Super Wideslab®.

Benefits of using Flood Super Voidslab®
Reduced Weight
Longer spans – reducing dead-weight
Faster Installation
Faster installation – twice as fast as Hollowcore to install
High Quality
High quality soffit finish – can be left exposed or painted
Two-Way Spanning
Spans in two directions – ideal solution for dealing with disproportionate collapse or progressive collapse design
Thermal Mass
Thermal mass and natural ventilation – exposed solid Flood Super Voidslab® is an excellent heat sink which is critical for natural ventilation
Reduced Building Height
Reduction in building height – shallowest structural floor zone available in the market
Flat Slab Construction
Can be used to construct a flat slab with no down stand beams – projecting steel links cast into the unit accommodates shear without the requirement for bearing
Flexible Openings
Openings can be easily accommodated – eliminates the requirement for trimmer beams
Sound Insulation
Better sound insulation (50% better) – Flood Super Voidslab® is 50% better sound insulated than Hollowcore
Shape Flexibility
Awkward shapes are easily accommodated – wet cast production allows for the forming of most shapes
No Cores
Solid slab with no cores – unlike Hollowcore, Flood Super Voidslab® is solid with no cores so it's an ideal solution for Car Parks with no fear of dripping from cores
Heavy Load Capacity
Heavy loads – the prestressed solid nature of the slab allows load to be redistributed and is an ideal solution for suspended service yards
Working Platform
Immediate working platform for other trades
Reduced Beam Depth
Reduced beam depth (up to 25%) – Flood Super Voidslab® can be designed to work compositely with steel and in-situ concrete beams, reducing the beam depth by up to 25%
Fewer Joints
Less soffit joints – the 2.4m wide units result in 50% reduction in soffit joints when compared to Hollowcore
Lifting System
Cast in Lifting system – fully anchored cast-in lifters are designed so that the units can be lifted from the trailer into final position without the need for cradles, chains or bearing into position
Vibration Control
Excellent vibration characteristics
