To date, it has been almost impossible to seal a pipe penetration that is already in place, unless there is sufficient annular space around the pipe to fit a link-seal mechanical seal system.
As most existing pipe-through-wall or bund situations do not have enough annular space around the pipe, there has not been a workable solution other than unreliable mastic systems.
Projex Group have introduced their UGA external wall sleeve to solve this problem. The sleeve is bolted to the outside of the wall around the insitu pipe – leaving enough annular space to fit the Link-seal system.
The Link-Seal system is then installed between the new sleeve and the pipe creating a water-tight penetration (can be oil resistant if needed).
This new system can accommodate pipes up to 1600mm in diameter.
