DENSO is leading innovator of solutions for joints in asphalt and concrete, with the world’s largest portfolio of passive corrosion prevention products for pipelines.

From SEALID®, the world’s first all-in-one solution, and our co-extruded DENSOLEN® three-ply tapes to TOK®-Band as a synonym for bitumen joint tape: For 100 years, we’ve been establishing ourselves as leading innovator, bringing countless patented solutions to the market.

Our innovations often inspire the development of new application techniques, significantly improving processes for construction site workers. Practical devices such as the DENSOMAT® or TOKOMAT® ensure that our products can be applied with maximum efficiency. 

A tradition of innovation

The development of DENSO®-Tape in 1927 is one of the earliest examples of our innovative spirit in action. In 1920s Berlin, the steel pipes that transported gas to homes and gas lanterns were still coated with liquid bitumen to protect them against corrosion. But bitumen becomes brittle after a short time, resulting in widespread damage across the city’s pipeline network. DENSO researched and developed a pioneering new approach. The invention of DENSO®-Tape – a plastic petrolatum tape – revolutionised the world of passive corrosion prevention and became the world’s first reliable passive corrosion prevention solution for pipelines. Today, the product is still marketed around the world as DENSO®-Tape.
