EROSION SEDIMENT CONTROL
PROJECT PROFILE
Lake Wabamun Shoreline Protection
Nilex provides erosion solutions for Lake Wabamun
clean-up.
Solution In the case of two adjoining landowners
whose property was directly affected by this
spill, CNs property remediation included removal
of the contaminated soil and their existing
shoreline revetment systems (four truckloads of
tires).
LOCATION Lake Wabamun, Alberta PRODUCT Armorflex
Articulating Concrete Block Revetment
System PROJECT PARTNERS Owner CN
Rail Consultant Paragon Soil Environmental
Consulting Completion Date September 2005
CN was responsible for installing new erosion
control systems on the properties to protect the
land from erosion and scouring caused by the
lakes wave action and by the ice movement during
winter months. The landowners requested an
alternative solution that would protect their
lake front lots from erosion, but would also
allow for the establishment of lawn vegetation.
Challenge As a result of a CN train derailment on
August 3, 2005, about 800,000 litres of heavy and
pole- treating oil were spilled in the Lake
Wabamun area, with an estimated 196,000 litres of
the oil spilling into the lake. CNs reclamation
agenda for environmental clean-up included
removal of all contaminated soil, vegetation and
old revetment systems from beach front properties.
Nilex recommended installing an Armorflex Class
50 articulating concrete block revetment system.
In addition to promoting lawn vegetation, the
Armorflex system would protect the lots granular
subsoil from ice scouring erosion. The Armorflex
system is ideal for installations in which both
permanent erosion protection and vegetation
establishment is required.

Lake Wabamun Shoreline Protection
Installation Nilex and Armortec Canada provided
technical support for installation of 19
Armorflex mats covering 235 square metres.
Challenging conditions included an elevated rail
track, steep incline, and a slippery access road.
The custom Armorflex system arrived on site as a
series of prefabricated mats. Using an excavator
and I-beam, the mats were installed over a site
specific geotextile on prepared subgrade. Above
the lake waterline, the mats were covered with a
layer of top soil and sod.

Wabamun have contacted Nilex about installing
Armorflex systems on their property to solve
