Usability

About

1. Cordek Cellcore HX B at 155mm thickness is a lightweight EPS board for placement beneath concrete beams and pile caps to counteract ground heave. Grade 13/18 accommodates concrete depths to 460mm and meets required performance criteria.
2. Durable and BBA-certified with NHBC compliance, it minimises upward forces using patented technology.
3. Multiple depths (85mm, 155mm, 220mm) and grades are obtainable, tailored to soil heave potential and insulation requirements beneath pile caps or beams.
4. Select panel depth based on soil heave risk. The product is straightforward to install and generates minimal dust 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 maximum force without failure, whilst fail load causes permanent deformation.
6. The 155mm HX B exhibits low shrinkage classification and plasticity index of 20-40.
7. Production costs align with grade and concrete depth, with Grade 7/10 offering 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, including 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.
