Envirolok Case Study with Gerber

Streambank Stabilization at Gerber Legendary Blades

In 2006 major storms in the Pacific Northwest, escalated stream volumes which eroded existing streambanks and began undermining the Gerber® parking lot and corporate sign.

Envirolok’s patented system was used to reinforce the parking lot and address the streambank erosion challenges.

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.

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.
