Collapsible void former with passive venting capabilities for use under reinforced concrete floor slabs. The product has a number of variables including depth and loading characteristics.
Designed for use beneath reinforced concrete floor slabs to protect against the potential effects of ground heave.
This product combines the benefits of Ventform with the Cellcore HX range. It alleviates the effects of ground heave and provides a gas venting medium. It is designed for use under suitably reinforced ground floor slabs. The depth is dependent upon the amount of ground heave that has been predicted.
