Usability

About

1. Cordek Cellcore HX B at 155mm thickness is a lightweight EPS board for placement under concrete beams and pile caps to counteract ground heave. Grade 24/32 is suitable for concrete depths up to 900mm and meets required performance specifications.
2. This product is durable, BBA-certified, and NHBC-compliant, effectively minimising upward forces using patented technology.
3. Multiple depths and grades are available, tailored to soil heave conditions and insulation requirements beneath pile caps or beams.
4. Select the appropriate board depth (85mm, 155mm, or 220mm) based on your soil heave risk assessment. Installation is straightforward with minimal dust generation when cut on-site.
5. Grade 24/32 indicates a safe load rating of 24 kN/m2 and a fail load of 32 kN/m2. Safe load represents the maximum force the board can sustain without failure, whilst fail load causes permanent deformation.
6. The 155mm HX B offers low shrinkage classification and a plasticity index ranging from 20-40.
7. Production costs vary by grade and concrete depth, with Grade 7/10 being the most cost-effective option compared to higher grades: 9/13, 13/18, 18/24, 24/32, and 32/42.

Design Notes

Each 155mm 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 in response to upward ground movement, known as the "FAIL LOAD."

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