Road Drainage/Crossings


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.


Stream Crossings

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

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...

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.
