Usability

About

1. 85mm Cordek Cellcore HX B is a lightweight EPS board for use beneath concrete beams and pile caps to counteract ground heave. Grade 24/32 accommodates concrete up to 900mm depth and meets performance requirements.
2. The product is durable, BBA-certified, and NHBC-compliant, reducing upward forces with patented technology.
3. Multiple depths and grades are available to suit different soil heave conditions and insulation requirements beneath pile caps or beams.
4. Select the panel depth (85mm, 155mm, or 220mm) according to soil heave potential. Installation is straightforward with minimal dust generation when cut on-site.
5. Grade 24/32 indicates a safe load of 24 kN/m2 and fail load of 32 kN/m2. Safe load represents the maximum force without damage, whilst fail load causes permanent deformation.
6. The 85mm HX B has low shrinkage classification and plasticity index of 10-20.
7. Production costs vary by grade and concrete depth, with Grade 7/10 offering the best value compared to higher grades: 9/13, 13/18, 18/24, 24/32, and 32/42.

Design Notes

Each 85mm Cellcore HX B grade is engineered to support a specific concrete thickness, plus a live load allowance of 1.5 kN/m2, with minimal creep compression over a 16-hour curing period. This is termed the "SAFE LOAD."

When the predetermined load is reached, the polystyrene legs of the Cordek panels will yield and collapse due to upward ground movement, referred to as the "FAIL LOAD."

In structural design, the slab, beam, or pile cap must be engineered to resist the difference between its self-weight and the fail load.
