Bentofix® Green – Reducing landslides – The future of sustainable sealing
In the picturesque Vögelsberg region of Tyrol, large-scale slope failures are a constant threat. Often caused by hydro-meteorological influences, these natural hazards require innovative and sustainable solutions. The EU project OPERANDUM aims to research effective and environmentally friendly measures to reduce landslides.
Base sealing system – Rainwater Harvesting Water Sustainability Project
With a surface area of 170,000 square meters and a depth of 10 meters, this artificial lake will be the first of its kind in India. It is being built to store one billion litres of rainwater over ten months, ensuring water availability throughout the year. The lake's construction relies on advanced technology, primarily Naue Carbofol® HDPE (high-density polyethylene) geomembranes, imported from Germany due to its exceptional durability and effectiveness in preventing water seepage.
Waterside seal – Safety and efficiency in levee construction – Oder levee reinforcement, Germany
The flood defences in the Neuzeller Niederung showed considerable stability problems during the Oder floods at the turn of the millennium. Only intensive levee defence measures were able to avert the danger of a levee breach and flooding of the hinterland.
Embankment stability works for reservoir renovation project – Grassholme Reservoir
This project shows how the reservoir's future resilience to high water levels can be ensured.
Secutex® Soft Rock – Coastal defence and flood protection, Scharbeutz, Germany
The approx. 5.4 km long coastal strip of the city of Scharbeutz, which is frequently used by tourists is characterised by a wide sandy beach with a beach wall and a promenade, road and buildings behind it. This stretch of coast is largely unprotected from storm surges from the northeast. The coastal defences needed to be improved to protect the residents in this area. The state of Schleswig-Holstein subsidised this construction project.
Bentofix® – GCL as geobarrier to levees – Levee reinforcement in Beesel, The Netherlands
Due to the consequences of climate change and increased river discharges, the levees in the Maas Valley were raised and strengthened in several places to protect the village of Beesel from flooding in the future.
Secutex® Soft Rock – Seabed Scour Remediation – Port of Southampton – UK
At ABP Port of Southampton’s City Cruise Terminal, Naue geotextile sand containers have been installed to remediate scour holes in the harbour bottom and prevent further scour. Southampton is the cruise capital of the UK, with over 430 cruise calls departing from the port each year. The port is one of the busiest deep-water ports in the UK and can accommodate any size of cruise ship. The port is also home to the UK’s second largest container terminal.
Bentofix® – Base Lining System in a Pond – Artificial Pond at Xiamen University, Sepang
To recreate a similar environment to the main Siming campus, an 8-acre lake will be constructed at the new campus in Sepang, Malaysia. Combined with the climate situation in Malaysia, it will be challenging to have an artificial lake with a permanent waterhead throughout the year. A solution for a pond lining system is required to contain the water inside the artificial lake and prevent water infiltration into the subsoil.
Bentofix® X, Secutex® – Base Lining System in a Dam – Mamak & Pernek Dam
The tropical nation of Indonesia receives over 600mm of rainfall in its mountain regions per year, resulting in an infrastructure of over 200 dams currently in operation (Ministry of Public Housing and Public Works / PUPR Indonesia, 2022). More than 70 of those are located in West Nusa Tenggara (NTB) Province, giving the highest concentration of dams in the nation. Dam construction peaked in the ‘90s and ‘00s, meaning today, the operation has been running for 20 to 30 years.
Bentofix® Secutex® – Sealing system for a new leisure lake – Thornwick Bay Holiday Village
Probably best known for its towering chalk cliffs and huge seabird colony, Flamborough Headland is also the location of one of four Haven holiday destinations on the Yorkshire coast. Since acquiring the site back in 2015, Haven has invested heavily in the refurbishment and expansion of the holiday park, and construction of the new lake, covering almost 2 hectares, is just one element of a 10-year masterplan for the Thornwick site and part of a multi-million-pound investment to modernise and improve the site’s overall appearance.
Bentofix® X – Meizhou Cultural Village – China
Meizhou City, now known as Meishan City, is a prefectural-level municipality in the Sichuan Province, China. More than 3 million inhabitants are registered in this city. Morphologically, the town is located south-west of the Sichuan Basin, a lowland region surrounded by mountains and drained by the Yangtze River.
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.
