Waterproofing of joints between concrete members.

摘要

The waterproof sealing of a joint between two abutting concrete members formed sequentially by pouring fluid concrete mix into formwork is achieved by (a) placing a waterstop hose on the formwork which will define one face of the joint in a first-formed concrete member; (b) at least partially surrounding this hose with material which prevents the fluid concrete from contacting that part of the hose which is adjacent to the formwork; (c) removing the formwork; (d) forming a second concrete member abutting against the first-formed member, thus providing the other face of the joint; and (e) pumping through the waterstop hose a sealing composition.
