Heinke Tunnel Seal Gasket
For the segmental lining of bored tunnels Trelleborg Ridderkerk supplies Tunnel Segment Gaskets (TSGs) under the trade name Heinke.
Since 1985, Heinke TSGs have been successfully supplied to major segmentally lined tunnel projects around the world. The TSGs, which are located in precast grooves encircling the mating faces of each segment, give a secure rubber-to-rubber waterproof seal as soon as the segments are bolted together.
