Application

  • For use as a compressible fill material in foundation construction.
  • Claymaster is not designed for use below concrete ground floor slabs.

Description

Claymaster is an EPS compressible fill material to reduce the pressure against foundations due to clay heave. Supplied coloured pink to easily differentiate from standard EPS. It is installed to the sides of deep trench fill and to the base and sides of concrete beam-piled foundations.


Features and benefits:

  • Tested and approved by the British Board of Agrément as a compressible fill material to reduce the pressure exerted on concrete foundations from expanding clay soils (clay heave).
  • NHBC approved.
  • Does not degrade when placed in high moisture areas and is resistant to the effects of freeze-thaw.
  • Will remain an effective compressible fill for the life of the building.
  • Ozone depletion potential (ODP) of zero and a global warming potential (GWP) of less than 5.
