Bentofix® Secugrid® Naue Steel P – Shooting range of the shooting sports club (SSC) Schale – Germany
The “Schale Shooting Sports Club” (SSC Schale) in Hopsten, Germany, invested almost € 5 million in constructing two new skeet shooting ranges with the support of the federal government, the state, and the municipality. For noise protection, a 24m high wall was built, also collecting the shotgun pellets for recycling. The wall material is mainly from soil aggregate with „environmentally relevant substances“ (e.g., milled material from road shoulders), which was used as fill material for the geogrid reinforced soil structure.
Secugrid® HS – Protective measures Laugneri II (Ost)
Between the Lake Zug, Lake Lauerz and Lake Lucerne in Switzerland rises a 1798m high mountain mass – the Rigi. The community Weggis is located between the lakefront and the steep south-western slope of the Rigi. Due to the morphological and geological conditions, various residential areas near the lake are seriously endangered by rockfall or landslides.
Secutex® Green – Visitor Centre Access Road & Car Park Area Northam Burrows Visitor Centre – North Devon
For the first time in the UK, a new and innovative biodegradable geotextile from Naue Geosynthetics has been used in the construction of an elevated access road and car parking area for the Visitor Centre at Northam Burrows Country Park on the North Devon coast.
Combigrid® Secugrid® – National Road L 133 in Grasberg – Germany
In Grasberg, Germany, asphalt concrete pavements in rural roads still exist. In this swampy area, also the state road L 133 was equipped with a stiff concrete pavement surface at that time.
Secugrid® – Development of Haulage Depot – Malaysia
Pulau Indah is an island off the coastal Klang district located about 40km from Kuala Lumpur, the capital of Malaysia. West Port, the largest port in Malaysia ranked 12th in the World Container Ports at the time of writing, is located on this island. Klang is well known for unfavourable ground conditions and engineering challenges for construction on the widespread soft clay deposits. The so-called “Klang Clay” consists of rather homogenous soft clay (SPT N
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.
Secumat® – Car Park – Germany
Around an approx. 50,000m2 car park for new cars of a German car manufacturer, a trench was planned to collect the surface water.
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.
Secutex® Green – Rehabilitation of Krainerwand & relocation of Mühlkanal – Germany
During the development of the „Goldmorgen Süd“ construction area near Stuttgart, Germany, a water retaining wall is erected facing the mill canal. Since the stability of this wall is massively impaired, a thorough rehabilitation is necessary.
