The sealing of these joints through internally-located seal systems (e.g. waterstop, hydrophilic rubber, injection hoses) is considered extremely problematic for various reasons. On one hand, problems are frequently encountered during concreting, especially around the base slab/wall joint. On the other hand, the water can run around the internal seal by climbing up the joint between precast concrete shell and in-situ concrete core, and then penetrate the structure through any existing cracks in the in-situ concrete.
