Waterproofing of joints between concrete members |
(57) 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 (5) on the formwork (4) which will define one face of
the joint in a first-formed concrete member (1);
(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.
