baiform counter-slope wedges GGK
Direct the water where it needs to go
Our counter-slope wedges, also known as backfall wedges, ensure that water always flows the right way and help prevent standing water. They are used to create slopes between the parapet and roof drains, providing long-lasting protection for your building fabric against moisture damage.
We offer premium counter-slope wedges made from extruded (XPS) or expanded (EPS) polystyrene foam, as well as rigid polyurethane foam (PIR/PUR), PET, mineral fibre or softwood fibre – perfectly tailored to your particular requirements.
Application
In the parapet area. The counter-slope wedges prevent rainwater from standing for long periods of time. Elevated expansion joints can easily be levelled positioning the counter-slope wedges along the adjacent surfaces.
