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 1220mm) reinforced concrete slabs, ground beams and pile caps. Further information on Cellcore HG suitability is available here.
Features
- 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
- Integral EPS insulation, permanent formwork for ground beams or voids for gases to vent options by request
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.
Applications
The Cellcore HG range is designed for use beneath deep (in excess of 1220mm) reinforced concrete slabs, ground beams and pile caps for the protection against the upward force associated with the effects of ground heave.
Suitability
Firstly, the depth of the Cellcore HG 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 HG required to achieve 'Equivalent Void' |
| Plasticity Index | Shrinkage Category | Void Dimension (mm) | HG (mm) |
| 10-20 | Low | 50 | 100 |
| 20-40 | Medium | 100 | 200 |
| 40-60* | High | 150 | 300 |
* 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 HG, as detailed in table two below:
Table Two:
| Grade | Safe Load (kN/m2) | Fail Load (kN/m2) | Maximum Concrete Depth * (mm) |
| 40/50 | 40 | 50 | 1540 |
| 50/65 | 50 | 65 | 1940 |
* Based on the Eurocode and a live load allowance of 1.5kN/m2.
For concrete thicknesses between 0mm and 1220mm please refer to the Cellcore HX data sheets. For concrete thickness above 1940mm, please contact the Cordek Technical Team on 01403 799600.
