Verified by manufacturer 3 months ago
A range of collapsible products designed to protect foundations from the effect of ground heave.
Application
Designed for use beneath reinforced concrete floor slabs, ground beams and pile caps to protect against the potential effects of ground heave.
Description
The product consists of a cellular construction of 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 that exceed the capacity of the standard Cellcore HX range.
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.
- Available with integral EPS insulation, permanent formwork for ground beams or voids for gases to vent by request.
