LEONHARD WESS has eight subsidiaries in Germany

SDC - Steinsanierung Denkmalpflege Crailsheim is one of the oldest subsidiaries with a history of almost 40 years. It was founded in 1987 under the leadership of the then partners and managing directors Werner Schmidt-Weiss, Wilhelm Wüst and road construction manager Kurt Köster. As investment at the time was increasingly going into renovation rather than new construction, they came up with the idea of setting up a 'heritage' department, which was incorporated into the road construction division. The stonemasons have little to do with civil engineering, but are artists with their own traditional craft. In 1994, the department became a wholly owned subsidiary. In 2008 it was renamed 'SDC - Steinsanierung Denkmalpflege Crailsheim GmbH & Co. KG'. To date, SDC has worked on prestigious projects such as Zwickau Cathedral and Oranienburg Palace. SDC is also a successful training company, even boasting a world champion among its young stonemasons.

Like its parent company, LEONHARD WEISS Fußbodentechnik will also be celebrating a milestone birthday in 2025. Founded in 1985, the subsidiary can look back on 40 years of practical experience in cleanroom flooring technology, during which time it has not only completed exciting projects but also invested a great deal of time in research and development. LEONHARD WEISS terrazzo floors are hygienically impeccable, easy-to-clean pharmaceutical floors with a pore-free, completely even and abrasion-resistant surface that can withstand high mechanical loads as well as heat or chemical agents and show no signs of damage where germs can accumulate, even after years of use. In addition, all floor connections such as platforms, drains or floor trolleys are completely sealed. Because of their hygienic properties, terrazzo floors are now the preferred choice in the pharmaceutical industry. The system solutions are also used in the cosmetics and food industries. But LW Fußbodentechnik has also left a lasting impression in the Mercedes-Benz Museum with its elegant, seamless and functional flooring.

The history of invatec began in 1997 in an office container on the former premises of LEONHARD WEISS in Brunnenstraße in Crailsheim. From the very beginning until his death, Werner Schmidt-Weiss was an important mentor who supported the team around the future managing director Volker Krauß in breaking new ground. Both the container and the rented premises in Gröningen soon became too small for the growing start-up under the management of Reinhold Münch, which is why the company moved into its own building in the Satteldorf industrial estate in 2012. invatec is best known for its innovative plastic cable ducts for Deutsche Bahn AG. Today, however, the company is active in a wide range of areas, including the development of a patented foundation for signalling systems and individual solutions in steel construction. A special feature are the 'Inno-Teams', which tackle special challenges, optimise processes or invent completely new special solutions. True to the motto:

VIA has been a traffic management professional for decades. Since 2017, the company has been a subsidiary of LW, enabling it to offer its customers another important component in the form of professional complete solutions. VIA specialises in the increasingly complex and demanding field of temporary roadworks traffic management. This includes the assembly and dismantling of all equipment, a 24-hour on-call service, all documentation, drawing up plans, applying to the authorities for traffic guidance, producing special signage and applying yellow markings.

FAST OPTICOM's speciality is the environmentally friendly and sustainable laying of fibre optic cables using the innovative FAST technology. The fibre optic cables are laid in the existing empty pipes and sewers in the buildings with the help of a robot. FAST OPTICOM is the only provider able to install fibre optic networks or broadband fibre optic cables in the existing sewer network quickly, cost-effectively and reliably without digging up the road surface. This means that no road closures are required as a small, safe working area is all that is needed for the robot to be deployed. This avoids noise pollution for local residents as well as the CO2 emissions that would be caused by conventional construction machinery such as excavators and asphalt pavers.

FRE (Focus Rail Engineering), founded in 2010, provides testing and engineering services for rails and switches. It specialises in non-destructive testing of tracks and rails for head checks (fine surface cracks in the track) and other external and internal rail defects. It uses techniques such as ultrasound and eddy current. FRE's staff are certified and supervise, among other things, the tracks in Deutsche Bahn AG's facilities. It also carries out inspections and quality control.

In 2014, AMG – Asphaltmischwerke Göppingen can be added. This plant supplies the LEONHARD WEISS road construction sites, among others. The mixing plant is responsible for the extraction and processing of raw materials. It produces rolled asphalt and accepts asphalt cuttings and asphalt rubble. The asphalt mixing plant is equipped with complex electronic control systems, which are used to precisely convert the recipes previously determined in initial laboratory tests into the finished product.

infra-tec (founded in 2019) is at home in the ever-changing world of digital processes. The young, innovative company designs, manufactures and assembles customised products and services for steel infrastructure. The company works with the latest methods such as BIM (Building Information Modelling), where all data is visualised in a virtual model. Its portfolio includes noise protection systems for roads and railways, roofing for public transport stops, such as the standardised platform roof of Deutsche Bahn AG, and signal holders and gantries for rail traffic. infra-tec has also developed rail dampers that reduce loud rolling noises and the well-known squeaking of trains in bends, and operates its own design office.
