We are the STM

We make roads. From motorways to decorative paths. From tried and tested to promising. Simply put, we live roads. Because by building, repairing and maintaining roads, we not only ensure that traffic flows - we connect people, we transport goods, we network the world - sustainably.

Our self-image

Many roads and paths are increasingly suffering from the effects of climate and traffic stress, which over time can lead to fatigue and wear and tear, even to destruction. This process must be counteracted by suitable repair and renovation measures so that structural maintenance is influenced in such a way that the requirements of safety and order are met. Süddeutsche Teerindustrie GmbH & Co. KG has been working on technologies for perfect road maintenance for over 110 years.

  • A bitumen emulsion is a mixture of bitumen, water and various emulsifiers. Both road construction bitumen and polymer-modified bitumen can be used to produce it. Depending on the type of bitumen emulsion, the proportion of bitumen can be between 40 and 70 percent.

    We would be happy to advise you on which bitumen emulsion is suitable for which substrate, road conditions and weather conditions.

    • only release water when setting

    • do not penetrate the soil
