WISTAPE® AFB PVC waterstop tapes should be used on the surfaces of the concrete that are in contact with water, in a way that prevents water leakage into the joints. If there is no pressurized ground water and it is desired to prevent the transfer of dynamic movements in the joint, then central type PVC waterstop tapes used in the center of the concrete cut can be used. If the structure is on an earthquake zone or is being built in places where flooding is expected to be intense, then a tape type that will absorb the excessive stresses that may occur and is resistant to the stresses in the cross directions should be selected.
