Roads and railways

We offer a range of geotextiles which not only extend the useful life of transportation infrastructures, but also make them more financially viable. These geotextiles have been specifically designed to meet the reinforcement, filtration, separation, and erosion control requirements of most civil works projects.

Geosynthetic applications have a wide variety of applications in any road or railway project.



Geosynthetics provide reinforcement in formation levels and roadbeds, increasing the bearing capacity of the earth, controlling differential settlements, and distributing loads.

Using a geosynthetic material can increase capacities with less competent soils, thereby reducing the resources needed


Geosynthetic materials are used as a separation layer to prevent the intermixing of the competent granular layers of the roadbed and the less competent soils of the formation level, as this would affect its capacities.  It is also used in railways to prevent the material of the formation level from intermixing with the track ballast to ensure the structural integrity of the superstructure.


Geotextiles are widely used for filtration and drainage in interior wall linings, piers, and trenches, in combination with granular materials (“French drain”), and their effectiveness has been more than demonstrated.

Geotextile materials facilitate the filtration of water, thus ensuring the granular material maintains its drainage properties. The choice of the correct material will also prevent the geotextile from becoming clogged up.

Complex geosynthetic systems (geocomposites), are also used in tunnels and disposal sites as they can drain large water flows with reduced thicknesses, without the need for packets of granular material.


Geotextiles are installed on embankments and slopes in order to control the erosion caused by water. The geotextile allows the water to seep into the ground, thus preventing landslips which could lead to the structure collapsing.


Geotextiles, and more commonly geogrids, are used to create green and reinforced earth walls. Geosynthetics make the soil more resistant, which allows almost vertical walls to be built without the need for interlocking blocks. These walls reduce negative visual impact and optimise construction costs.
