Provision for adequate drainage is of paramount importance in road design and cannot be overemphasized. The presence of excess water or moisture within the roadway will adversely affect the engineering properties of the materials with which it was designed. The destructive effect of flowing water increases as its velocity increases impacting the quality of the road. An efficient drainage system allows water to flow away from the roads cross-section as quickly as possible by reducing, or eliminating, the amount of flowing water.
When projects need to cross a waterbody for temporary or permanent access roads, forestry, mining, pipelines, railroads, cable crossings, or transmission lines, there are strict guidelines in order to protect fish and other wildlife habitat. The use of bridges or steel arch culverts can be...
Sub-surface drainage systems should be utilized in areas where soil is unable to drain quickly on its own. Highways, paved roads, gravel roads, parking lots and laneways require sub-surface drainage in order to remove water that can accumulate under the surface after rainfall which can lead to...
The Colorado Department of Transportation (CDOT) was facing drainage issues behind existing retaining walls along a section of Highway 40 as it climbs over the 11,307 foot summit of Berthoud Pass, just west of Denver, Colorado. Over time, hydrostatic pressure and freeze/thaw caused sections of...Read More

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.
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.
The CULTEC system was simple to install. We will be recommending, and looking forward to using the Cultec system for future projects.
We love you guys for getting this project [Energy Environmental Experiential Learning (EEEL) Building Grounds] completed in the timelines required.
