Cordek Cellcore HX B Under Beam 220mm (Foundation Protection Board) 32/42 is specially designed eps block for use beneath reinforced concrete ground beams and pile caps to protect against the potential effects of ground heave.

HX B Under Beam (Ground Heave Solution) Grade 32/42 is calculated and calibrated for concrete thickness up to 1220mm (has been tested to achieve the specified performance characteristics).

220mm Cellcore Under Beam HX B is a lightweight but durable BBA certified ground heave solution which meets the NHBC’s (National House Building Council) Technical Standards.

Cellcore HX B is a 220mm thick moulded polystyrene block used to reduce the upward force transmitted to the structure from ground heave (Patented Product Technology).

The depth (85mm, 155mm or 220mm) of the Cellcore HX B panels should be determined by the heave potential of the soil.

One of great things about Cellcore HXB Under Beam is its very simple to work with and doesn't have much dust off when cut on site.

Under Beam EPS Grade 32/42 means that safe load is 24 kN/m2 and fail load is 32 kN/m2 (kN - kilonewtons per m2).

Safe load is a maximum safe force that a Cordek’s Cellcore HX B material offers without fear of breaking.

Fail load is not safe force and will cause permanent deformation of the HX B under beam eps board.

The shrinkage category of 220mm Cellcore HX B is classified as high and the plasticity index is 40-60.

The cost of manufacturing 220mm cellcore hxb is considered linearly proportional to its grade which is based on maximum concrete depth.

HX B Under Beam Grade 7/10 price is the lowest compared to the higher grades: 9/13, 13/18, 18/24, 24/32 and 32/42 (Cordek Cellcore price list is available upon request).

The standard range of cellcore products are available in a variety of depths and grades to suit most commonly encountered combinations of soil heave potential and concrete depth.

Variations of the HXB product are also available for use under pile caps and ground beams or alternatively where integral insulation, permanent formwork or passive gas venting is required.

Cordek Cellcore 220mm HX B Under Beam Installation Guide:

 · The procedure for installing Cellcore HX B EPS block is straightforward.

 · Please ensure that Cellcore Under Beam Boards are placed upon a suitable firm and level surface. 

 · Typically a layer of concrete blinding beneath the HX B panels is recommended.

 · The lightweight but durable polystyrene panels can be easily laid by one person. 

 · Where they are required to be cut this can be carried out using a fine tooth saw or hot wire cutter.

Storage and Handling:

All products are delivered in a polythene wrapping and are clearly labelled. 

Both packs of Cellcore and individual panels can be manually handled and offloaded upon delivery, taking in to account any site specific manual handling regulations.

No further storage requirements are needed as the product is unaffected by both UV light and water.
