Geosynthetics for roads and civil engineering | Naue

Q: How do geogrids reinforce roads and reduce cost?

Secugrid® and Combigrid® geogrids interlock with the aggregate to distribute traffic loads, reducing rutting and required layer thickness. This extends pavement life, cuts aggregate volumes and lowers whole-life maintenance costs on both paved and unpaved roads.

Q: What are the advantages of geogrid-reinforced bridge abutments?

Reinforced-soil abutments built with Secugrid® are ductile, tolerate differential settlement, are faster and cheaper to construct than massive concrete abutments, and have been proven on reference projects such as the Prüm bridge in Minden.

Q: How do retaining walls and MSE structures work?

Layers of Secugrid® or Combigrid® reinforcement are placed within compacted fill to create a mechanically stabilised earth mass that retains steep or vertical faces, replacing reinforced concrete with a flexible, durable, lower-cost structure.

Q: Why replace granular drainage with Secudrain®?

Secudrain® geocomposites provide a high, defined in-plane flow capacity in a thin layer, replacing thick granular drainage layers behind walls, tunnels and basements. This saves space and aggregate and delivers reliable, long-term groundwater control.

Q: How are roads sealed to protect groundwater?

In water protection zones, Carbofol® HDPE geomembranes and Bentofix® GCLs seal the subgrade and embankment so that road run-off and spillages cannot reach groundwater, in compliance with the RiStWag guideline. For more information please see our solutions for groundwater protection.

From paved and unpaved roads to embankments on soft ground, retaining walls, bridge abutments, structural drainage and groundwater sealing, Naue supplies the geosynthetic solution for each of these areas.

Naue’s Secugrid^® and Combigrid^® geogrids, Secumat^® erosion control mats, Secudrain^® drainage composites and / liners extend service life and lower lifecycle cost, all backed by full conformity documentation.

Yes. Geogrid-reinforced base courses and basal reinforcement distribute loads over very soft subgrades, controlling settlement and enabling construction where unreinforced solutions would fail or require costly soil replacement.
