Back in 1952, DEKOTEC Gmbh invented TOK®-Band: the world’s first reliable channel sealing product. The need to protect our environment while also focusing on cost-effective solutions has resulted in the development of innovative products for sealing connections and tapered joints in channels, pipes and shafts.

In 2013, DEKOTEC GmbH invented TOK®-Sil Resist and took another step forwards in groundwater protection for the biogas industry.
