An expansion type water bar shall be provided either centrally in a wall or on the soffit of a floor.
The join is as watertight as the waterbar that join them.
Further a water bar could be provided if the wall is constructed to retain the water.
Pvc waterstops water stops are flexible plastic strips which provide a physical barrier to water at concrete joints mostly in basements water retaining structures like water tanks swimming pools structural foundations other below ground level constructions.
When there is a water bar in the construction joint in the wall it could or it could not continue through the base.
Concrete joints are most liable to seepage.
Waterbars or waterstops are strip like elements which are usually made of galvanized steel copper rubber bituminous material or plastic material.
