A story of successOver the past century the mother company of DEKOTEC GmbH has built a reputation founded on experience, quality and reliability in corrosion prevention and innovative sealing technology. Just a few years after the company was founded in 1922 in Berlin, the company revolutionised corrosion prevention across the world with the Petrolatum tape, its very first invention. When the company premises were destroyed during the Second World War, the firm relocated its headquarters to a new site on the banks of the Rhine river. The company did not let this setback damage its inventive and entrepreneurial spirit, as testified by the countless corrosion prevention and sealing technology innovations it rolled out over the following years. Today, it comprises a global group of companies that, in spite of its international reach, still strives to deliver sustainable custom solutions and provide personal service to its customers.
Rising in the midst of collapse
14/11/1922: The company is founded in Berlin under the name Chemieprodukte GmbH. Against the backdrop of a post-war 1920s Germany that is suffering famine, hyperinflation and unemployment, the company lays the foundations for its future "Made in Germany" story of success.
A name for success
1927: The brand name is registered. The name comes from the Latin word "densus", which means "to seal".
Customer satisfaction as a catalyst for success
1929: The company wins Berlin's municipal gas authority, or Berliner Städtische Gaswerke AG (GASAG), as its first customer. Many national and increasing numbers of international municipal authorities and pipeline operators follow suit: Stadtwerke München (the Munich municipal authority), Ruhrgas AG Essen and the Blackstone Gas Company in the USA are all impressed by the new technology.
From the Spree to the Rhine
1946: After the destruction of the company's original premises during the Second World War, the company reforms in Leverkusen. The proximity of the new site to BAYER AG and the Rhine river provides the inspiration for new inventions – and an efficient transport route.
TOK®-Band: A flexible and stable channel solution
1952: TOK®-Band– a ready-made malleable tape solution for channel sealing – is invented. Up until this point, the only sealing methods available used hot casting or filler. However, these solutions produced a seal that was too rigid, leading to the seal breaking whenever the pipe moved in the ground.
BUTYLEN: Preserving value with three-ply tape
1972: The company invents the world's first co-extruded three-ply tape for welding connections on pipes and pipelines. A brand new cold-application technology is used to fuse the layers of the tape together, creating a hose-type permanent seal.
TOK®-Band: Taking quality to the roads
1977: The world's first bitumen joint tape for joints and seams in asphalt road construction is invented. The TOK®-Band name quickly becomes a synonym for all bitumen joint tapes.
DEKOTEC®: Rapid application – permanent seal
2006: DEKOTEC® heat shrinkable sleeves featuring innovative hot-melt and mastic technology are launched. The product line is known for its outstanding quality and simple, fast application.
TOK®-SIL Resist: A new product for new partners
2014: The world's first joint sealant for biogas plants and liquid manure, slurry and silage effluent plants provides an effective, permanent seal at the critical point – the intersection between horizontal and vertical joints. The invention of TOK®-Sil Resist is of particular interest to operators of biogas plants.
TOK®-Band: Improve the proven - Develop new ones
2017: 40 years after the introduction of the first TOK® bitumen joint tapes for road construction, the application of the new TOK® tapes is now possible without any primer. As of now, the customer applies the tapes considerably faster and the environment is protected. - Another proof of the innovative power of DEKOTEC GmbH.
