Cellcore HX B

*Grade 13/18 Suitable for concrete groundbeams up to 460mm*
*Grade 18/24 Suitable for concrete groundbeams up to 660mm*

For ground beam protection under piled beams. Widths between 300mm and 1200mm, in 25mm increments. Other widths available.

450mm and 600mm available from stock. All other widths will be manufactured to order so please expect a slightly longer delivery time.

The new Cellcore HX range, designed after an extensive R&D program, alleviates the effects of ground movement on foundations. Cellcore HX works on the same design principles as standard Cellcore but provides a much improved performance. Cellcore HX is a fully moulded patented system

Suitability

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

Results of the soil analysis.  NHBC Cat.           Predicted ground movement or BRE/NHBC req.    Depth of cellcore HX required to achieve "Equiv.Void".

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 below:

Grade 7/10. Safe Load (kN/m2) 7, Fail Load (kN/m2) 10, Maximum Concrete Depth 220 (mm)

Grade 9/13. Safe Load (kN/m2) 9. Fail Load (kN/m2) 13. Maximum Concrete Depth 300 (mm)

Grade 13/18. Safe Load (kN/m2) 13. Fail Load (kN/m2) 18. Maximum Concrete Depth 460 (mm)

Grade 18/24. Safe Load (kN/m2) 18. Fail Load (kN/m2) 24. Maximum Concrete Depth 660 (mm)

Grade 24/32. Safe Load (kN/m2) 24. Fail Load (kN/m2) 32. Maximum Concrete Depth 900 (mm)

** 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.
