155mm x 900mm x 1200mm Heaveguard Pile Collars are compressible low density Expanded Polystyrene products, used when foundations need to be protected against ground heave.

The Heaveguard (Claymaster) pile collar is an engineered material in green or pink color designed to safeguard piles against uplift damage caused by expansive clay soils.

It is securely fitted around the pile, providing a squared edge for seamless integration with Cordek Cellcore HX S Under Slab and Cellcore HX B Under Beam panels.

Typically, it is manufactured to match the beam width and the expected heave depth of the Cellcore, and it can feature either a circular or square hole for installation.

Pile Collars are designed to aid the installation of the Cordek Cellcore panels by fitting securely around the pile and providing a square edge for the Cellcore panels to be butted against.

Claymaster Pile Collars consist of low density expanded polystyrene, coloured green or pink for easy identification on site, and available in a variety of different collar sizes and thicknesses.

Each Heaveguard Pile Collar is generally manufactured to suit the width of the ground beam and the thickness of the Cellcore panel it is being used in conjunction with.

The void within the Pile Collar is designed to suit the diameter of the pile, with each pile collar available in two segments to aid installation.

Standard Claymaster (Heaveguard) pile collar thicknesses available are 85mm, 155mm and 220mm.

Cordek Heaveguard Pile Collars Installation:

 · For piled ground beams, Heaveguard is generally only required on the inside face of external ground beams, as indicated in the NHBC guidelines.

 · Typically the material will be placed against the face of the beam after striking of the formwork and prior to backfilling.

 · If a permanent formwork system is used to cast the beams then the formwork should be dimensioned such that the Heaveguard will fit inside the former prior to concreting.

 · For use in deep trench fill applications the excavation width should accommodate the width of the foundation and the thickness of the Heaveguard required.

 · Care should be taken to ensure that the Heaveguard is adequately supported so that it remains in the correct position during the placement of the concrete.

 · Typically, the excavation will be founded 500mm below the zone of influence, and the Heaveguard installed in accordance with NHBC requirements, i.e. 500mm above the bottom of the trench and on the inside face of the excavation.
