The mechanical pipe penetration seal – link-seal – is a non-corrosive system which provides long-term leak protection and structural integrity.

Link-seals can be used in combination with century-line sleeves, cell-cast discs and other products.

For more than 20 years Projex Group have been supplying the link-seal system to major infrastructure projects across Australia. These include gas plants, oil refineries, hospitals and waste treatment plants where the sealing of the penetrations is extremely critical and of the highest importance.

Link-seal mechanical seals are truly the premier method for sealing pipe penetrations and will exceed expectations. Link-seals are extremely robust and are specially formulated to withstand attack from ozone, sunlight, water and a wide range of chemicals.

The link-seal system has no down time on curing and unlike most grouts, foams, epoxy’s or cementitious products they do not shrink whilst curing and require no maintenance afterwards.
