Both products are manufactured in Germany.
How different is the link-seal pipe penetration seal compare to the traditional sealing method?
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 extremely robust & specially formulated to withstand attack from ozone, sunlight, water and a wide range of chemicals. They have no down time on curing and unlike most grouts, foams, epoxy or cementitious products they do not shrink whilst curing & require no maintenance afterwards.
