*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
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".
Plasticity Index Shrinkage Cat. 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 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.

Our drawings required Cellcore CC, but was advised by Lemon that that has been replaced with Cellcore HXB. Everything worked fine, its surprisingly strong for polystyrene.
The new Cellcore HXB is much better then the previous Cellcore. The older product (Type CC) was bits of polystyrene glued to the underside of the plastic, but it is now moulded as one section. This makes it much stronger, and when you cut it to length, it doesn't fall apart. I still think the product is expensive, but it is good quality.
Easy to install and not affected by weather. We have used this product for over 15 years.
Excellent product for ground heave. Serves purpose well, and very established in the Industry.
Simple but effective. Easy to use on site.
Great product, looks good, well presented. Easy to use
Easy to install. Handy to have cut to width to the width of the trench saved me time
5 star. Excellent. Easy to use.
