Roads and Railways

The construction of major works such as roads and railways requires carefully planned interventions to ensure long-term operation and user safety. Base reinforcement, the construction of road and railway embankments, retaining structures such as reinforced earth walls, block or panel walls, and slope erosion protection are all interventions that can be carried out using Tenax geosynthetics.

01

Basic reinforcement

The innovative Tenax 3D GRID has been developed to minimize subsidence in applications such as roads and railways, where longitudinal loads can create dangerous depressions in the asphalt or railway track, reducing the useful life of the structure.

To increase the bearing capacity of the foundation soil of an embankment, bidirectional geogrids must be installed: thanks to their tensile strength, they provide resistance to the soil and increase its mechanical characteristics. The High Modulus Tenax LBO HM and Tenax GT HM geogrids and geocomposites are designed to deliver superior performance in the field of low deformation, i.e., in the actual operating conditions of the structure.

Reinforcement of railway ballast

Ballast reinforcement is essential for reducing maintenance costs: Tenax LBO 370 geogrids are certified by the UK and Dutch railway authorities and designed to improve the characteristics of large-sized materials used in railway bases.

Retaining structures

Tenax RIVEL reinforced earth systems and Tenax T-BLOCK block systems have been used worldwide to construct embankments with reduced dimensions, cutting costs and construction times.

Slope protection

Weather conditions can cause slopes to wash away, preventing vegetation growth and creating gullies and channels. Tenax MULTIMAT three-dimensional geomats and Tenax TENWEB geocells are products designed to protect slopes. They are extensively tested and, thanks to their ease of installation, do not require special equipment.
