Secumat® – Heidlandgraben – Germany

While expanding the surface drainage of an industrial area in Hamburg-Harburg, the Heidlandgraben was expanded. The cross-section of the drainage channel had to be given a larger volume in the confined space between the plots of land and thus be able to hold more capacity. For this reason, it was necessary to make the slopes relatively steep. The subgrade formed a sandy subsoil, on which the topsoil for the greening required additional support against surface-parallel erosion phenomena.

Secugrid®HS – B91, Expansion of the federal highway between Deuben and Werschen – Germany

The federal highway B 91 between the cities Deuben and Werschen in Germany is a main road with a collector access to the A9 motorway. The subsoil risks resulting from former lignite mining activities represent an enormous challenge in the region. Subsidence has occurred regularly in the past.

Secutex® Soft Rock – Geotextile wall Lubmin – Germany

At the seaside resort of Lubmin (Mecklenburg-Vorpommern, Germany), the storm surge in 2017 and two storm surges in 2019 led to a substantial decline of the dune due to erosion, so that short-term action was needed. Due to the cramped conditions on site, the State Office for Agriculture and the Environment (StALU) could not construct the coastal protection dune according to its intended cross-section. In case of an imminent complete erosion of the dune in the event of a storm surge, an additional construction had to take over the function as the last barrier against breakthrough.

Secugrid® – Bridging of mining voids at Day-Care Centre “Albrecht-Dürer-Straße” – Germany

The new day-care centre “Albrecht-Dürer-Strasse” in Halle (Saale), Germany will provide room for 200 kids and is part of a municipal investment programme. The site is located on the edge of a 150-year-old mine. A special underground mining technique called “room and pillar caving” was used to extract brown coal. This method does not fill the created cavities after extraction of the coal. As a result, the overlying rock layers settle after the mining operations and fill the cavities. It can, however, not be precluded that residual cavities may cause subsidence at the surface of the terrain. Based on these findings, safety measures had to be taken in the area of the open space of the day-care centre.

Secugrid® HS – Electrification “Südbahn”, Ulm Central Station – Germany

The oldest railway line in Württemberg, Germany, the „Südbahn“, will be electrified and upgraded for a maximum speed of 160km/h. As part of the rehabilitation works, an old bridge near Langenargen will be replaced. In order to create sufficient working and storage space for the construction work, a 4,900m2 large working platform was built directly next to the railway line.

Bentofix® X – Huawei Song Shan Lake – China

Huawei Ox Horn Campus was developed on the south shore of Songshan Lake, Dongguan, Guangdong Province, China. The Europeanthemed model village consists of 12 groups of buildings, inspired by European cities or regions. The buildings will be used as Huawei’s Research and Development Centre with a capacity of 25.000 employees and a total GFA of over 1 million square meters. The total cost of the entire complex is around $1.5 billion.

Secugrid® – Srinakarin – Romklao Road – Thailand

Over the past 10 years the Bangkok Metropolitan Region has experienced an increase in the traffic volume due to rapid urbanisation. Bangkok Metropolitan Administration as the local government considered it necessary to accommodate the changing traffic flow with the realisation of the Srinakarin – Romklao Road Project. The 11.2km long road is expected to reduce the traffic between the western and eastern region of Bangkok, especially in the Hua Mak Region. A total of 5.5 billion Baht (150 million US$) investment has been made for this project.

Secutex® Soft Rock – Protection shore Bang Muang – Thailand

The Bangsak Beach, which is located at Bang Muang, Takua Pa district, Phang Nga province of Thailand, has been frequently visited by both tourists and locals due to its beautiful beachfront. The existence of the beach is important to the local economy and especially to tourism in the region.
