BBA Agrément Certificate
Collapsible void former for use under reinforced concrete ground beams and pile caps. The product has a number of variables including panel width, depth and loading characteristics.
Designed for use beneath reinforced concrete ground beams and pile caps to protect against the potential effects of ground heave.
Comprising a cellular construction of moulded expanded polystyrene combined with a robust polypropylene board, 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:
Expanded polystyrene (EPS).
Width available from 300–1200 mm in 25 mm increments to suit ground beam.
