Application

Designed for use beneath reinforced concrete floor slabs to protect against the potential effects of ground heave.

Description

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.

Features and benefits:

  • Provides combined ground heave protection and gas venting capabilities in a single product.
  • Range of thickness and grades to suit most project requirements.
  • Light, robust and easy to install panels.
  • All variations include drainage slots to alleviate water pressure.
  • Unaffected by UV light and water.
  • Can be connected to the Cordek range of perimeter vents to vent hazardous ground gasses from beneath the building footprint to the atmosphere.

Application:

Designed for use beneath reinforced concrete floor slabs to protect against the potential effects of ground heave.
