Description

The BEWI Ground Heave Protection boards are a cellular-structured void formers cut from expanded polystyrene (EPS). The boards are manufactured in a range of thicknesses to meet the application – Beam, Slab or Insulated Slab - requirement and the soil plasticity and predicted ground movement on the site. All BEWI Ground Heave Protection boards are supplied with a bonded polypropylene top and bottom sheet.


Features and benefits:

  • Protects a buildings ground beams and or in-situ suspended reinforced piled floor slabs against the upward pressure caused by ground heave.
  • BBA-certified.
  • Meets NHBC Technical Standards.
  • Board sizes aid a fast, easy installation.
  • Bonded bottom sheet removes need for sand/ cement blinding layer.
  • Available with bonded EPS insulation board.
  • Lightweight boards limit H&S risk on site.
