Heave Stopper
Heave Stopper is used for Protecting structures against clay heave and ground heave movement.
Groundbeams and slabs can be cracked by the pressure that ground movement causes when concrete foundations are built on shrinkable soils such as clay and expansive shale soils, or when development is on reclaimed land or subject to ground recovery caused by deep excavations. The structural damage caused by clay is well understood by engineers and designers all over the world. Here in the UK the problem is particularly acute in the South East although climate change is having its effect on soils in other parts of the country.
