Usability

About

1. The 85mm Cordek Cellcore HX B is a lightweight EPS board for use beneath concrete beams and pile caps to counteract ground heave. Grade 13/18 is suitable for concrete up to 460mm depth and meets required performance criteria.
2. This product is durable, BBA-certified, and NHBC-compliant, effectively minimising upward forces using patented technology.
3. A range of depths and grades are offered, adaptable to soil heave conditions and insulation requirements beneath pile caps or beams.
4. Select the appropriate panel 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 13/18 delivers a safe load of 13 kN/m2 and fail load of 18 kN/m2. Safe load represents the maximum force the board withstands without failure, whilst fail load indicates permanent deformation threshold.
6. The 85mm HX B features low shrinkage classification and a plasticity index ranging from 10-20.
7. Manufacturing costs vary according to grade and concrete depth, with Grade 7/10 offering the most economical option 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, including a live load allowance of 1.5 kN/m2, with minimal creep compression over a 16-hour curing period. This is defined as 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."

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