Secutex® Green – Temporary use of a biodegradable separation and filter nonwoven

The Wilhelm-Wisser-Schule (WWS) in Eutin, Germany, is bursting at the seams. For this reason, the school is planned to be expanded into a three and a half form entry school for around 550 pupils over the next few years. However, lessons will continue. As an alternative location, an interim school for the WWS will be set up on the fairground for around two years ....

Secugrid® – Repair of flood damage „Leubethaer Street“ in Freiberg – Germany

In May 2018 a storm front hit the Vogtland region in Germany with full force. Up to 150l of rainfall were measured in one hour. In the Adorf district of Freiberg the heavy rainfall caused the greatest damage of the storm. Over a length of 30m the Leubethaer Street was washed away. A culvert located in this area could no longer absorb the enormous quantities of water. This led to a water accumulation within the road embankment. Fine particles of the fill soil were successively washed out and the slope collapsed completely.

Secutex® Green – Renaturation/relocation of the Erft river near Neuss-Gnadental – Germany

The Erft is a southwestern and left tributary of the Rhine, about 107 km long. Its course and water flow have been changed many times since the Middle Ages. In July 2021, some parts of Germany experienced continuous rain and floods, also in the catchment area of the Erft. In many places, the Erft overflowed its banks considerably, for example, in Bad Münstereifel and Erftstadt-Blessem, where - intensified by a rushing current - major damage was caused. Shortly before it flows into the Rhine, the Erft, which has been straightened over the past decades, is to be renatured, and the meandering course of the existing old arms is to be reconnected to the watercourse. This measure is part of the „Lower Erft“ perspective concept. The concept includes the near-natural redesign of the 40km long section of the Erft river from Bergheim to Neuss. Here, the Erft is being adapted to the reduced water flow (about a quarter of today‘s volume) associated with the end of lignite extraction.

Bentofix® Secudrain® Secugrid® – Storm water retention pond Ziegenschleppe – Germany

To improve the water retention capacity and the flood protection situation in the tributary to the Zwickauer Mulde after the devastating floods on the Mulde and Elbe in 2002, additional water retention areas were created. In the town of Schneeberg on the Schlema, a storm water retention pond was constructed in 2005 with a utilisation volume of approximately 23,400m³. The main components also included an inlet and two outlets as reinforced-concrete structure, an emergency spillway as a rough ramp, 28m of DN 1400 drainage channel and, in addition, the entire mechanical and electrical equipment of the inlet structure.

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.
