French Broad River – Del Rio,TN
1 Year After Completion
A section of bank had been severely damaged due to flooding conditions during the construction of a new bridge. The bank erosion threatened both the recently installed bridge infrastructure and adjacent railroad line. TDOT called for rip rap to be placed at the toe of the slope for temporary stabilization. A regulatory directive was also imposed, requiring an engineered, permanently vegetative stabilization method be implemented.

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. 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. 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. 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. Environmental Remediation at Crosby, MS 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. 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.
