003. Description of Detail
It is important that the rainwater is able to flow freely to the drainage points. This is achieved by cutting a hole in the drainage layer and insulation around the outlet and to the same diameter. A KSR Inspection Box is then placed above the opening and supported on the drainage layer. The KSR Inspection Box in conjunction with the KLS Gravel Board and Diadrain Drainage Layer ensures that the water reaching the outlet is clear of any material that may cause an obstruction.
