225mm Cellcore HX S Under Slab EPS

225mm Cellcore HX S is a product specially designed to provide foundation protection from ground heave effects when installed under reinforced concrete floor slabs. It is consisted of specially moulded hexagonal cellular expended polystyrene, available in a number of different depths and grades. Ground movement is caused by the rehydration of clay or expansive shale soils, overburden recovery resulting from deep excavations or, in certain parts of the world, permafrost heave.

APPLICATION

Cellcore HX S panels are used for reinforced concrete slabs protection from the effects of ground heave.

CHARACTERISTICS

• Available in a number of grades, suitable for different applications;
• Moulded for consistent performance and durability;
• Reduced depth and therefore less excavation;
• Less upward force is transmitted to the structure;
• Suitable for most lightweight slabs;
• Cost effective and reduced carbon footprint;
• BBA certified and in accordance with the NHBC’s Technical Standards.

Depending on the chosen grade, the boards are designed to support specified safe-load during a 16 hours period, with compression of less than 5. On the other hand, depending on the chosen depth of the product, it will collapse by a specified amount, under the product’s specified fail-load.

the safe-load is determined as the level of support of thickness of concrete each grade of the product can offer, plus a live load allowance of 1.5 kN/m2 with negligible creep compression during the given curing period of 16 hours. The fail-load is determined as the load under which the panels and polystyrene legs will collapse under the influence of the upward ground movement.

INSTALLATION

The Cellcore HX S can be installed in a quite straightforward procedure, with standard precautions and safety procedures followed, as specified for EPS boards. For more specific instruction, please refer to this Data Sheet.
