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 9/13 accommodates concrete up to 300mm thick whilst meeting performance specifications.
2. The product is durable, BBA-certified, and NHBC-compliant, reducing 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 panel depth (85mm, 155mm, or 220mm) according to soil heave potential. Installation is straightforward with minimal dust generation when cut on-site.
5. Grade 9/13 delivers a safe load of 9 kN/m2 and a fail load of 13 kN/m2. Safe load represents the maximum force the product withstands 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 with 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 accommodate a specific concrete thickness, along with a live load allowance of 1.5 kN/m2, while experiencing minimal creep compression during a 16-hour curing phase. This is referred to as the "SAFE LOAD."

Upon reaching the predetermined load, the polystyrene legs of the Cordek panels will yield and collapse due to the upward ground movement, a condition known as the "FAIL LOAD."

In the structural design process, it is imperative that the slab, beam, or pile cap be engineered to withstand the disparity between its self-weight and the fail load.
