Application

Designed for use beneath reinforced concrete ground beams to protect against the potential effects of ground heave.

Description

Comprising of a cellular construction of moulded expanded polystyrene combined with a robust polypropylene permanent formwork, which has been designed and tested to tight tolerances to achieve the specified performance characteristics. It is available in a variety of depths and grades to suit the most commonly encountered combinations of soil heave potential and concrete depths.


Features and benefits:

  • Reduces the upward force transmitted to the structure.
  • Wide range of depths and grades to suit most applications.
  • Meets the NHBC Technical Standards.
  • Consistent performance supported by extensive testing.
  • Integral, permanent formwork to suit the depth / width of the ground beam.
  • Manufactured to suit ground beam dimensions, range of accessories available.
