Wrimco SBS Sanded Cap sheet membrane that was spot torched to a blinding slab with the base of a water storage tank now laid on top. Once the blockwork walls are built, the surplus elastomeric 3mm membrane will be torched onto the wall and membrane will be subsequently applied to the dirt line.
The reason for choosing the Wrimco SBS sanded membrane was for the concrete slab to adhere to the membrane. It is the upside down equivalent of a roof where we need the membrane to stick to the roof slab to prevent any water tracking.
