Owner: Alberta Transportation
Consultant: Alberta Transportation, Nilex
Contractor: Carillion Canada
Completion Date: July 2010
A 220 m ditch along Highway 497 continued to erode more and more each year. Over time, the velocity of surface water run-off along the ditch caused deep gullies. Yearly repetitive maintenance was ineffective. Alberta Transportation required a more effective and long-term erosion control system.
Nilex recommended a long-term erosion control system that included the installation of VMax3 P550 turf reinforcement mat (TRM), ShoreMax soft revetment scour system, and Nilex’s GeoRidge check dams.
Turf reinforcement mats provide long-term erosion protection along the ditch channel and the GeoRidge check dams assist in reducing water flow velocities and erosion, allowing for vegetation establishment. ShoreMax was installed around the culvert inlets and outlets to provide another layer of erosion protection from scouring.
Together, this system provides long-term erosion protection and vegetation establishment to the ditch channel.
The Vmax3 P550 turf reinforcement mat was installed the full length of the ditch. 45 cm (18 inch) rebar stakes anchored the mat and GeoRidge was installed every 3.3 m (11 feet) to dissipate the flow of water.
ShoreMax’s scour protection mats were installed at the inlet and outlet of each culvert. The flexible interlock system allows for easy installation in adverse conditions.
This erosion control system provided a much-needed permanent solution that requires little to no maintenance. By installing the Vmax3 P550 turf reinforcement mat, the client achieved a savings of over $28,000 versus traditional 300 mm riprap while reducing carbon emissions by 89% (64.1 tonnes of CO2 saved).
