The 160mm Cordek Cellcore HX S Grade 32/42 functions as a protective barrier beneath reinforced concrete floor insulation slabs, effectively reducing ground heave impact by limiting upward force transmission to your structure.
Engineered and calibrated for concrete depths up to 1220mm, the Anti Heave Board undergoes rigorous quality testing to guarantee consistent compliance with specified performance standards.
Our comprehensive product range includes various depths and grades suited to typical soil heave scenarios and concrete thicknesses. We also supply specialist variants for pile cap applications, ground beams, or projects needing integrated insulation, permanent formwork, or passive gas venting.
The 160mm Cellcore HX S range protects reinforced concrete floor slabs from upward forces generated 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 additional allowance for live loads of 1.5 kN/m², whilst maintaining minimal creep compression over a 16-hour curing period. This combined capacity is termed the \"SAFE LOAD.\"
When the predetermined load threshold is reached, the polystyrene legs of the 160mm Cordek panels will buckle and collapse due to underlying ground movement, referred to as the \"FAIL LOAD.\"
During design, ensure the slab, beam, or pile cap is sized to accommodate the difference between its weight and the fail load, as shown in the design examples provided.
