The 90mm Cordek Cellcore HX S Under Slab Grade 18/24 functions as a protective barrier beneath reinforced concrete floor insulation slabs, reducing the effects of ground heave by limiting the transfer of upward forces through the structure.

Engineered with precision, the Anti Heave Board—specifically the 90mm Cordek Cellcore HXS Grade 18/24—is calibrated to handle concrete depths up to 660mm and has undergone extensive testing to guarantee consistent performance delivery.

Key Attributes:

1. Reduces upward force transmission to the structure caused by ground heave.
2. Provides a range of profiles and grades suited to different project requirements.
3. Carries BBA certification for assured quality and dependability.
4. Meets NHBC Technical Standards, confirming compliance with industry best practice.
5. Verified by BRE Global for Environmental Product Declaration (EPD), demonstrating environmental responsibility.
6. Created using precision moulding techniques for reliable, uniform performance.
7. Available with optional Filcor insulation for permanent ground beam formwork or passive gas venting.
8. Backed by patented technology offering distinct performance benefits.

Our standard range includes various depths and grades to suit the typical soil heave potential and concrete depth combinations typically required. We also supply specialist variants for applications beneath pile caps and ground beams, as well as options with integrated insulation, permanent formwork, or passive gas venting capabilities.

Applications

The 90mm Cellcore HX S range protects reinforced concrete floor slabs from upward forces generated by ground heave effects.

Usability

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.

Design Notes

1. Each 90mm 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."

2. When the predetermined load limit is reached, the polystyrene legs of the 90mm Cordek panels will buckle and fail due to upward ground movement—referred to as the "FAIL LOAD."

3. 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 on the following page.
