Hydraulic engineering

Sealing, filtration, scour and erosion protection for water structures

Canals, dikes, dams, reservoirs, levees, coasts and offshore structures all need sealing, filtration and erosion protection, and Naue supplies the solution for each of these areas.

Naue’s Bentofix® GCLs and Carbofol® HDPE geomembranes seal water structures, Secugrid® geogrids and Secutex® nonwoven geotextiles stabilise and rehabilitate defences, and Secutex® H filter mats and Secutex® Soft Rock sand containers protect against scour and wave attack, all with full conformity documentation.

Dyke construction

Engineered geosynthetic solutions for levees/dykes provide flood protection even on soft or problematic subsoil. GCLs, geogrids, and filter geotextiles deliver proven, norm-compliant solutions for new-build, rehabilitation and reinforcement projects.

The image shows the installation of the geosynthetic clay liner (GCL) during embankment rehabilitation, creating a durable, low-permeability barrier for long-term flood defence performance.

Dyke rehabilitation

Dyke/levee rehabilitation restores ageing flood embankments to current standards. A geosynthetic clay liner, high-strength geogrid, filter geotextile and erosion control mat form a complete system for sealing, reinforcing, filtering and protecting levees.

On the seabed, a precisely arranged circular scour protection layer of sand-coloured Naue Secutex® Soft Rock Sand Containers (GSC) surrounds the monopile, protecting the foundation while leaving the corrosion protection intact. Two offshore technicians stand on the working platform, inspecting the installation under bright daylight.

Scour protection

Engineering of geosynthetic structures used to prevent or reduce the erosion of sediment around offshore foundations, harbour facilities, bridge piers, and other hydraulic structures caused by flowing water, waves, and currents.

Hydraulic engineering: frequently asked questions

A watertight barrier of Bentofix® GCL and/or Carbofol® HDPE geomembrane, protected by Secutex®, is installed along the bed and slopes. This stops seepage and water loss that would otherwise reduce efficiency in irrigation, navigation and storage.

Secutex® geotextile filter mats and Secutex® Soft Rock sand containers stabilise the seabed and bank material around offshore foundations, bridge piers and harbour structures, preventing the erosion of sediment caused by currents and waves.

Secutex® Soft Rock sand-filled geotextile containers and filter geotextiles defend shorelines, dunes and infrastructure against wave attack and erosion, providing a flexible, durable alternative to rock riprap.

Bentofix® GCLs provide the sealing core, Secugrid® geogrids add stability on soft subsoil, and Secutex® filters prevent internal erosion. Together they seal, stabilise and rehabilitate dikes, dams and ageing levees for reliable flood protection.

A Bentofix® GCL delivers the sealing performance of about a metre of compacted clay in a layer only millimetres thick, self-seals minor damage on hydration, installs faster and removes the need to source and place large clay volumes.

Yes. Naue hydraulic products are engineered for long-term submerged and cyclic loading and conform to EN ISO 10318, with full conformity documentation for standards-compliant water-engineering projects.
