Cellcore HX B

Cellcore HX B is designed for use beneath reinforced concrete ground beams and pile caps to protect against the potential effects of ground heave. The product consists of a cellular construction of Filcor EPS (Expanded Polystyrene) which has been designed, moulded and tested to tight tolerances to achieve the specified performance characteristics.

Features

  • Reduces the upward force transmitted to the structure from ground heave
  • Wide range of profiles and grades to suit most applications
  • BBA certified
  • Meets the NHBC’s Technical Standards
  • Moulded production for enhanced and consistent performance
  • Available with integral permanent formwork
  • Patented Product Technology

The standard range of products are available in a variety of depths and grades to suit most commonly encountered combinations of soil heave potential and concrete depth. Variations of the product are also available for use under floor slabs or alternatively where permanent formwork is required.

Applications

The Cellcore HX B range is designed to protect reinforced concrete ground beams and pile caps from the upward forces associated with the effects of ground heave.

Suitability

Firstly the depth of the Cellcore HX B panel should be determined by the heave potential of the soil, as detailed in table one below:

Table One: 

Results of the Soil Analysis NHBC Category Predicted Ground Movement or BRE/NHBC requirement Depth of Cellcore HX required to achieve 'Equivilent Void'
Plasticity Index Shrinkage Category Void Dimension (mm) HX B (mm)
10-20 Low 50 85
20-40 Medium 100 155
40-60* High 150 220

* When the analysis exceeds 60 or a deeper void is required, please consult our Technical Team.

Secondly, the grade of the product is determined by the depth of the concrete to be cast on the Cellcore HX B, as detailed in table two below:

Table two:

Grade * Safe Load (kN/m2) Fail Load (kN/m2) Maximum Concrete Depth ** (mm)
7/10  7 10 220
9/13 9 13 300
13/18     13 18 460
18/24    18 24 660
24/32  24 32 900


* For easy identification the panel labels are coloured as shown.

** Based on the Eurocode and a live load allowance of 1.5kN/m2.

For concrete thicknesses between 900mm and 2000mm, further grades of Cellcore are available. For further advice please contact the Cordek technical team on 01403 799600.
