As infrastructure ages, its condition becomes more critical. As does the importance we place on it. Transport networks worldwide undergo constant change, wear and tear—and, as a result, need ongoing expansion, development, and repair.

Monitoring and surveying

We have provided testing, monitoring, and surveying services to the transport sector since 1999—supporting a wide range of assets from highway structures and runways to waterways and marine infrastructure.

We also provide automated monitoring for railway earthworks, structures, permanent way, buildings, overhead line equipment (OHLE), and other critical assets. 

Ongoing data-collection

Our manual and automated monitoring of geotechnical systems and assets supports infrastructure across the transport sector—measuring conditions, status change, and the surrounding environment.

Prediction and detection

Smart systems can predict external incidents like floods and snow that can affect structural safety—and detect structural problems before they become serious. 

Data-driven decision making

Asset data pinpoints the root cause of structural problems for diagnosis and repair and informs confident budgeting decisions—making infrastructure safer, stronger, and smarter.

Geotechnical systems

The expansion of motorways by adding more lanes often requires comprehensive earthworks—and results in the formation of high, steep embankments in the cut slopes and hills. 

Our engineers use ground anchors and soil nails to ensure the entire soil wedge, including the slip circle, is secured, stabilized, and consolidated.  Ground anchors and soil nails protect the soil wedge from tilting, sliding, gliding, shear failure—and loss of position. 

We also use soil nails or rock bolts to secure shotcrete construction or prefabricated concrete segment walls in the soil at the face—and to fix rockfall protection mesh in place.

The use of passive systems is appropriate in stabilization projects—and when the soil nails are only loaded when movements start in the slope or at the face. 

At full load, the pressure applied by the earth is absorbed and transferred by the soil nails. In projects where deformations are important, engineers will apply an active system, like ground anchors, in place of soil nails.

DYWIDAG geotechnical products support rail networks above and below ground

DYWIDAG geotechnical products are used above and below ground on rail networks, from soil nails and rock bolts to slope protection mesh and ground anchors. 

Micropiles are used in applications with a low overhead—and in the rehabilitation of existing bridges and viaducts. 

DYWIDAG systems support construction, maintenance, and repair of highways worldwide

The addition of new lanes to expand existing highways and motorways can require comprehensive earthworks—and result in high, steep embankments in the cut slopes and hills. 

DYWIDAG ground anchors and soil nails are used in the construction of new highways—and in the upgrade, strengthening, and repair of existing structures, slopes, and cuttings.
