mastaVOID is a honeycomb design cardboard sacrificial formwork void former. The perfect solution for void former in clay reactive soils.

Manufactured using 100% FSC Certified material. This product is a much more environmentally friendly option over foam. Reduce your business' environmental impact by saying no to foam.

Reactive soils occur across Australia. They are clay-type soils that swell and shrink during wetting and drying. These soils contain a higher proportion of clay, affected by moisture.

Damage to building resulting from ground movement can be costly. This impact is often not seen for many years after the project is complete.

A Solution To Reactive Soils

mastaVOID is the premier void forming solution for engineers and builders.

Engineered to create space between the soil and building foundation. Void forming lessons the upward pressure transmitted to the structure due to ground lift.

mastaVOID has the ability to support concrete load during pouring. Due to the degradable properties, mastaVOID will break down over time leaving a void.

Having a genuine void under the concrete reduces the risk of reactive soils impact. Damage from soil moment and pressure places upon the slab will be reduced.
