The 160mm Cordek Cellcore HX S Grade 24/32 acts as a protective barrier beneath reinforced concrete floor insulation slabs, reducing the impact of ground heave by limiting upward force transmission to your structure.
Engineered and calibrated specifically for concrete depths up to 900mm, the Anti Heave Board has undergone thorough testing to guarantee consistent performance against specified criteria.
Our range includes various depths and grades to match typical combinations of soil heave risk and concrete thickness. We also supply specialist variants for pile caps, ground beams, or applications requiring integrated insulation, permanent formwork, or passive gas venting systems.
The 160mm Cellcore HX S range protects reinforced concrete floor slabs from upward forces caused by ground heave effects.

For concrete thicknesses between 1220mm and 2000mm, further grades of Cellcore are available. For further advice please contact the InsulationBee Technical Team on 02038839057 / 02038839057.
Each 160mm Cellcore hxs grade is engineered to support a specific concrete thickness, plus an allowance for live loads of 1.5 kN/m², whilst maintaining minimal creep compression over a 16-hour curing period. This is termed the \"SAFE LOAD.\"
When the predetermined load limit is reached, the polystyrene legs of the 160mm Cordek panels will buckle and collapse as the underlying ground moves upward—this is known as the \"FAIL LOAD.\"
During design, ensure the slab, beam, or pile cap is sized to handle the difference between its weight and the fail load, as shown in the design examples provided.
