Coastal protection – Flexible and proven with Geotextile Sand Containers (GSCs)
Smart, scalable and sustainable defence systems for coastlines at risk – with Secutex® Soft Rock from Naue
The challenge: Coastal areas under threat
Storm surges, heavy rainfall, and sea level rise are increasing due to climate change. Coastal zones are particularly vulnerable to flooding and erosion. Without effective protection, infrastructure and habitats are at high risk.
Our Response: Geotextile Sand Containers
Naue provides a flexible and field-tested solution: Secutex® Soft Rock geotextile sand containers (GSCs). These are installed as a revetment to stabilise coasts, dunes, riverbanks or embankments – protecting them from erosion and scour caused by high hydraulic loads.
Key benefits:
- High flexibility and robustness
- Easy to install, using local sand as fill
- Cost-effective and environmentally compatible
- UV-resistant and proven in real-world applications

Proven worldwide – Successful use in practice.
From the North Sea to the tropics, Secutex® Soft Rock has been successfully deployed in a wide variety of hydraulic engineering and coastal protection projects – ensuring safety, flexibility and sustainability.
North Sea project: Protection of a severely eroding dune for more than 35 years – withstood many storm surges without damage.
Singapore project: Erosion control along an urban coastline – significant stabilisation
Germany project: Coastal erosion protection – Maintenance costs reduced by 40 %.
Thailand project: Coastal protection – long-term cost reduction achieved.
Your Project – Our Solution
Coastal regions face increasing pressure from storm surges and erosion.
Secutex® Soft Rock geotextile sand containers provide a proven, adaptable and environmentally conscious solution. By absorbing wave energy and stabilising shorelines, they help reduce damage, minimise maintenance costs and contribute to long-term coastal resilience.
