Coated metal water stops have been established to be simple and secure solutions in sealing construction cold joints. After decades of use, these waterstops have proven themselves to be effective, durable and highly reliable. However, in the event of unanticipated joint movement, late shrinkage or ground movement, the primary seal can become compromised and crack injection may be necessary to seal the joint.
The use of a redundant waterproofing system can alleviate this problem. Preferably, an injection hose system for multiple injections is installed in tandem with the coated metal water stop.
There are several different options for injection, depending on the selected type of injection hose:
Both systems allow for multiple injections. Intec® Premium can be flushed using compressed air and Intec® Cem N needs to emptied via vacuuming.
