Roads and Rail


Nilex’s engineered road and rail improvement systems make the construction of roads, highways, pads, runways, yards and light to heavy Class 1 rail structures and intermodal facilities more economical. When compared to traditional construction methods, Nilex's systems significantly reduce the amount of natural aggregate required while increasing structural performance. Structures built with Nilex geosynthetic products cost less, are faster to build, last longer and minimize environmental impact by using less gravel and energy in construction.

Roads and Rail Applications

Paved Structures

All pavements will wear out over time, even those constructed on firmer subgrades; however, Nilex can help to significantly extend the design life of your pavement structures while lowering construction costs and reducing the amount of aggregate and asphalt used versus conventional construction...

Unpaved Structures

The required aggregate layer thickness of unpaved surfaces - particularly in heavy equipment yards and industrial working areas - is primarily dependent on axle loads, vehicle passes and subgrade strength. Weak subgrades combined with heavy wheel loads and intense traffic will cause unpaved...

Haul Roads

Heavy haul roads and access roads leading to and from areas such as mine operations, wind farms, oil drilling sites and landfills are subject to continuous heavy traffic resulting in severe deterioration if left untreated. Not only are there costs to maintaining these roads on a regular basis...


Stormwater management is critical to ensure the long-term success of our roadways. Proper drainage of a roadway creates a safe driving environment by minimizing roadside ponding and sheeting. Nilex’s prefabricated drains provide maximum drainage capacity with a minimum need for trenching and...

Rail Structures

The American Railway Engineering and Maintenance of Way Association (AREMA) has recognized the value of geogrid technology for trackbed stabilization by including a chapter on geogrid in its 2010 Manual for Railway Engineering. Several factors including, but not limited to, car weights, car...

Clarke Lake Road Bypass

The Clarke Lake Road bypass was constructed to divert truck traffic from residential areas and provide a shorter alternate route for industry traffic...

I want to thank you for getting things organized as quickly as you did for us and for the follow up calls and site visits that allowed us to get this work done and meet our schedule dates for the road work. As well, your product knowledge and ability to provide the technical support when dealing with the consultants was a major help in getting the system approved and installed correctly.

Bob T, Project Manager, MGP Construction Ltd.

Not only was there a substantial cost savings realized by the client, there was also a benefit to the road structure as well. The original design road structure number was 3.780 and a calculated traffic (ESALs) of 2,147,000. The revised road structure number using the TX5 is 4.260 and a calculated traffic (ESALs) of 4,593,000.

Nilex was an invaluable asset in the successful completion of the Troutbrooke Drive Slope Stabilization project in Toronto, by providing engineering assistance, installation training and continuous on and off site technical support.

Terraprobe Engineering

The CULTEC system was simple to install. We will be recommending, and looking forward to using the Cultec system for future projects.

Kang Construction

We love you guys for getting this project [Energy Environmental Experiential Learning (EEEL) Building Grounds] completed in the timelines required.
