Usability

About

1. The 85mm Cordek Cellcore HX B is a lightweight EPS board designed for placement under concrete beams and pile caps to counteract ground heave. Grade 32/42 is suitable for concrete depths up to 1220mm and meets required performance specifications.
2. This product is durable, BBA-certified, and NHBC-compliant, minimising upward forces through patented technology.
3. A selection of depths and grades are offered, adaptable to soil heave conditions and insulation requirements for pile caps or beams.
4. Select the board depth (85mm, 155mm, or 220mm) based on soil heave potential. Installation is straightforward, and on-site cutting produces minimal dust.
5. Grade 32/42 indicates a safe load of 32 kN/m2 and a fail load of 42 kN/m2. Safe load represents the maximum force the board withstands without failure, whilst fail load causes permanent deformation.
6. The 85mm HX B has a low shrinkage category and plasticity index of 10-20.
7. Manufacturing cost varies with grade and concrete depth, with Grade 7/10 being 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, 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 yield and collapse due to upward ground movement, known 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.
