A contractor went beyond the allowed limits of construction permitted by regulatory agencies, and excavated a streambank. The US Army Corps of engineers, cited a violation and required it to be restored quickly and promptly.

The DuPage County Department of Environmental Concerns recommended the Envirolok System as an appropriate repair to the streambank.

Streambank Stabilization

 

Streambank Stabilization

Sophia Creek, Barrie, ON Canada

Urban Streambank Stabilization

Years of flooding and multiple 100-year storm events lead to failure of the stream channel, banks and slopes surrounding an existing culvert.  By utilizing Envirolok as a long-term solution, the project team was able to quickly establish native vegetative cover that continues to withstand urban storm events.

Stormwater Swale Repair at Edgefield Golf Course

Residential subdivision development upstream of a stormwater swale increased impervious surface runoff causing severe scour of more than four feet.

Envirolok’s Patented system was used to build a “mattress” of Envirolok units that encapsulated the soil, prevented erosion and served as a medium to vegetate the swale.

Glenorchy Trail, Oakville, ON

Permanent Vegetated Solutions

Due the scouring action of Sixteen Mile Creek, the subsurface clay shale of this steep slope was quickly eroding and no longer stable.  The heavily utilized trail system was in danger of failing.

Envirolok was installed in combination an cabled earth anchoring system  to provide additional stability and restore the native vegetative cover.

Shoreline Erosion Stormwater Management Case Study

Seawall Replacement Project on Lake Waubesa in Mcfarland, Wisconsin.

In August 2007, near record rain caused flash floods and high water throughout the Midwest. The existing railroad tie seawall at one residence failed completely drifting into the lake.

Made from a soft, durable fabric, Envirolok is safe for children, pets and recreational water equipment; making it a responsible and permanent solution to replace the sea wall.

An abandoned creosote plant from the 1940’s left a legacy of creosote leaching into the adjacent river.  A two step process of cleanup and remediation was required.

Envirolok encapsulated soil bags were able to repair the shoreline and restore the biological function of the streambank, enhancing the diversity of plants and providing new habitat for riparian species.

Tree Protection

Protecting a heritage tree using Envirolok vegetated system

Erosive conditions including ice heave at a Battle Point Park on Lake Osakis,  caused an undercut in the shoreline endangering a heritage tree.

Envirolok system’s combination of geotextile manufacturing with biological aspects of nature was the ideal solution. The soft armor system of Envirolok can withstand severe ice heave  and the pressures of Central Minnesotta ice buildup. The Envirolok system not only protects the tree but provides ecological and biological service to the lake as well.
