BBA Agrément Certificate
Certificate type
Collapsible void former with integral permanent formwork for use under reinforced concrete ground beams. The product has a number of variables including panel width, depth and loading characteristics.
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.
