The Link-Seal System

From creating a perfect circular hole to quickly, efficiently & permanently seal the annular space around pipes passing through wall, floor or ceiling, Projex Group have the products & expertise to provide the long term no leak solution.

Link-Seal® are supplied as a belt with a series of interconnecting rubber links & bolts that when tightened form a mechanical seal between the outside of the pipe & the substrate it passes through.

They are widely recognised in the industry as the most effective way to permanently seal this gap known as the annular space. The Link-Seal System is used to seal around the outside diameter of pipes passing through walls, floors or ceilings.

Whether your pipe or the substrate that it passes through is constructed from HDPE, plastic, concrete or one of our specially manufactured steel sleeves, then Link-Seal provides the ultimate no-leak solution for the sealing of the annular space.
