In 1909, the Homberger family of manufacturers from Karlsruhe applied in Malsch to build and obtain a business permit for the "Adolf Homberger roofing felt factory". At this time, Adolf Homberger already had a factory at Sophienstrasse 146 in Karlsruhe. Both plants had the same corporate purpose: roofing felt and tar products (asphalt roofing felt, asphalt-gravel, felt and lead insulation, asphalt putty, goudron (= tar), preservation products for railway sleepers and telegraph poles).

The business and building permit was issued to Adolf Homberger on August 19, 1909. At that time the factory area covered approx. 2700 m². Through appropriate acquisitions, barter transactions, etc. The property has expanded to 21,000 m² until today.

After a fire on November 12, 1913, Adolf Homberger applied for the factory to be rebuilt with minor additions (motor for electricity, warehouse).

On April 15, 1914, Gustav Schlapper's widow from Karlsruhe acquired the property including industrial and office facilities in Malsch. At that time, the industrial facility was still destroyed by the fire. On April 22, 1914, the local mayor's office was again requested to rebuild, which was approved on June 10, 1914. From this it can also be read that in the fire in Adolf Homberger's factory, the new owner was asked for compensation, which triggered the transfer of property.

The new Schlapper owners owned another tar production facility, "Schlapper AG" in Darmstadt . In Malsch , the company operated under: "Roofing felt - tar production Malsch - Gustav Schlapper Witwe".

The letterhead dated May 27, 1915 shows that the company's product range went from roofing felt, wood cement, asphalt putty, wood tar, tar ropes to tar insulation panels. From this letter to the Grand Ducal District Office in Ettlingen it can be read that two more stills are to be put into operation in May 1915 in order to meet the increasing number of orders. Since the Schlapper widow had not yet had a business permit, the building application was only granted on May 31, 1920, whereby it can be assumed that the construction was already completed in 1915 and that production, measured by client and purpose, was continued without interruption.

A building drawing from 1920 shows that the administration building was in the same place as today's social facilities. Production systems correspond to the current location of the emulsion system, and there was also a steaming device at the same location as today. At that time, a raw material store was located where our agitators are today.

The company was then sold to Schlapper AG on November 14, 1923 and integrated. On April 8, 1925, the Saarland Meguin Group acquired the operations in Malsch and Darmstadt. The operations in Malsch and Darmstadt were operated and maintained by the Group's own subsidiary “Süddeutsche Teerverwertungs AG” (Südteerag for short). On February 26, 1927, Süddeutsche Teerverwertungs AG moved its headquarters from Darmstadt to Malsch.

Shortly after the restructuring and expansion, the group ran into economic difficulties that threatened its existence. On February 8, 1928, the executives of Südteerag, August Peter and Theodor Lauer each bought 50% of the company shares in Südteerag from the impending insolvency. This is also evident from a letter to the Ettlingen district administration.

After excerpts from the land registry, August Peter changed the Süddeutsche Teerverwertungs AG to the sole proprietorship "Süddeutsche Teerindustrie August Peter" on January 10, 1935. The purpose of the company at that time was concentrated on roofing felt and tar products. At that time - and partly until today - the company was known under the name "Dachpapp-Peter" or "Teer-Peter". Dachpapp / Teer-Peter is listed under “Heimatfreunde-Malsch e. V. “in connection with the construction of the so-called Eulenburg (in honor of Til Eulenspiegel) in 1921. This suggests that August Peter was already active in the roofing felt industry before he acquired the tar industry.

On February 14, 1945, the southern German tar industry and other local companies (such as the Eckerle joinery, which is still neighboring today), were badly damaged by a bomb attack. On March 25, 1945, the southern German tar industry was completely destroyed after another bomb attack.

Around 1955 the company had the following products in its range: road tar , tar and bitumen varnishes, tar oils , tar and asphalt products, sealing materials and roofing felt .

August Peter sold the "Süddeutsche Tarindustrie August Peter" on December 28, 1959 to today's shareholders, who already had many years of experience in road construction and wanted to expand accordingly. Today's company, Süddeutsche Teerindustrie GmbH & Co. KG, or STM for short, was founded on December 21, 1959 by the new shareholders through a partnership agreement. The company was first registered on February 17, 1960. Süddeutsche Teerindustrie GmbH (general partner of STM) was founded on December 16, 1959 by means of a partnership agreement. The company was first registered on December 18, 1959.

Company purpose

The purpose of the company is the distillation of raw tar and the further processing of the distillates, the production of all kinds of tar products, cold asphalt, cut bitumen, building protection agents, insulation compounds and other products of the tar and asphalt industry, as well as the sale of such products.

In other words, STM manufactures bituminous products for road construction, road renovation and building protection. All products manufactured in-house are processed using the so-called cold paving process (i.e. no hot asphalt or similar). In addition to selling these products, STM also rents out vehicles and equipment for the installation of such products. (e.g. repair train for a surface treatment, ramp sprayer for applying composite materials, etc.).

When it was founded, the company was located on Bietigheimer Weg, which later became Benzstrasse in Malsch. In 2005 the previous address was changed from Benzstraße 11 in Otto-Eckerle-Str. 7-11 changed.
