Usability

About

1. The 155mm Cordek Cellcore HX B is a lightweight EPS board for installation beneath concrete beams and pile caps to prevent ground heave. Grade 7/10 is suitable for concrete depths up to 220mm and meets required performance criteria.
2. This product delivers durability, holds BBA certification, and complies with NHBC standards, effectively minimising upward forces using patented technology.
3. A selection of depths and grades are offered, each tailored to specific soil heave conditions and insulation requirements for pile caps or beams.
4. Select the appropriate panel depth (85mm, 155mm, or 220mm) according to soil heave potential. Installation is straightforward, and cutting on-site generates minimal dust.
5. Grade 7/10 indicates a safe load capacity of 7 kN/m2 and a fail load of 10 kN/m2. Safe load represents the maximum force the board withstands without failure, whilst fail load causes irreversible deformation.
6. The 155mm HX B exhibits a low shrinkage category and a plasticity index ranging from 20-40.
7. Production costs vary 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, incorporating a live load allowance of 1.5 kN/m2, whilst experiencing minimal creep compression over a 16-hour curing period. This threshold is defined as the "SAFE LOAD."

When the predetermined load is reached, the polystyrene legs within 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 manage the difference between its self-weight and the fail load.
