Cellcore HG

Cellcore HG is designed for use in ground heave protection applications, where the requirements of the project mean that the standard Cellcore HX product range is not suitable. Usual applications include the use beneath deep (in excess of 900mm) reinforced concrete slabs, ground beams and pile caps.


  • Reduces the upward force transmitted to the structure from ground heave
  • Wide range of profiles and grades to suit most applications
  • Suitable for use beneath deep slabs, ground beams and pile caps up to 1940mm in depth
  • Available in standard or ‘cut to beam width’ panel sizes

The Cellcore HG panels are available in a variety of depths and grades to compliment the standard Cellcore HX range. The product comprises of a cellular construction of Filcor (Expanded Polystyrene) which has been designed and tested to tight tolerances to achieve the specified performance characteristics.


The Cellcore HG range is designed for use beneath deep (in excess of 900mm) reinforced concrete slabs, ground beams and pile caps for the protection against the upward force associated with the effects of ground heave.

Case Study

Moorgate Shaft

Cordek were approached to provide a solution for the ground heave protection requirements of the reinforced concrete slab at the base of Moorgate Shaft. We were called upon to ascertain the appropriate protection needed, taking into consideration the weight of reinforced concrete slab and the heave potential of the soil beneath, along with the space and delivery constraints in place on site.
