100mm Heaveguard - Expanded Polystyrene Board Used Against Ground Heave - 2400mm x 1200mm

100mm Heaveguard is a compressible low density Expanded Polystyrene (EPS) board, used when foundations need to be protected against ground heave and against lateral heave. Heaveguard is used to prevent potential problems in foundations due to moisture movement in soils, such as clay heave, reducing pressure on ground beams in piled foundations, and on the sides of trench fills. The expansion and contraction process during wet and dry periods is known as clay heave and this can cause severe problems with foundations. Heaveguard can be used as permanent shuttering for cast in-situ reinforced concrete.

• When foundations need to be protected against ground heave and against lateral heave.

• A rapid, cost effective solution to clay-heave problems,
• The initial compression of the material during casting can be disregarded,
• It is rot-proof and durable and will withstand the conditions encountered below ground,
• It will not degrade in the presence of high levels of ground water or precipitation.
