Connection between an existing and new subways
Connection between an existing and new subways
(OP)
I have a problem about extension of an existing subway.
I did diaphragm wall before and I understand it is not difficult to make a NEW diaphragm wall watertight by placing waterstops before concreting.
However, I have no clue of how to make waterstop fitting into the slabs and walls of the existing subway.....
