Usability

About

1. This 220mm Cordek Cellcore HX B lightweight EPS board is designed for placement beneath concrete beams and pile caps to counteract ground heave. Grade 32/42 accommodates concrete depths up to 1220mm whilst meeting required performance criteria.
2. The product is durable, BBA-certified, and NHBC-compliant, effectively minimising upward forces through patented technology.
3. Multiple depths and grades are offered, adaptable to varying soil heave conditions and insulation requirements beneath pile caps or beams.
4. Select the appropriate panel depth (85mm, 155mm, or 220mm) according to soil heave potential. Installation is straightforward with minimal dust generation when cut on-site.
5. Grade 32/42 indicates a safe load of 32 kN/m2 and fail load of 42 kN/m2. Safe load represents the maximum force without failure, whilst fail load causes permanent deformation.
6. The 220mm HX B exhibits low shrinkage characteristics and a plasticity index of 40-60.
7. Production costs vary by 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 220mm Cellcore HX B grade is engineered to support a specific concrete thickness, incorporating a live load allowance of 1.5 kN/m2, with minimal creep compression during a 16-hour curing period. This is referred to 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, 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.
