Envirolok Featured in APWA Fox Valley Branch Project of the Year – McDonald Road Bridge Replacement

Congratulations to Brandon Buzzell and the project team at Baxter & Woodman Consulting Engineers for “Public Works Project of the Year Award” In the Fox Valley Branch APWA. The McDonald Road Bridge Replacement Project (Elgin, IL), features both the Envirolok system and Native Vegetated Mat.

Here’s what Brandon had to say about the project – “The 1:1 embankment slopes east of the bridge needed to be constructed of a material that could blend in with the natural surroundings, while also offering constructability and durability with a height of over 10 feet.  The design team contacted Envirolok to discuss the feasibility of their Reinforced Soil Slope (RSS) product.”


“The unique advantage of the Envirolok RSS was their proprietary interlocking geotextile bags, which can be integrated with standard “geogrid” soil reinforcement to create a reinforced soil mass.  The system can be installed similar to a segmental block wall, but at any desired slope; thus the ideal 1:1 slope could be constructed as well as transition slopes at each end.  The units are filled with a sand-topsoil mix that provides a substrate for vegetative growth without sacrificing strength.”

“To create the instant-green effect desired by the community, Envirolok teamed with its sister company Agrecol Native Plant Nursery to develop a pre-vegetated mat that can be attached directly to the face of the Envirolok system.  This Native Vegetated Mat features a mix of short prairie grasses as specified by IDOT and is salt-tolerant, low-maintenance, and is reinforced with a natural coconut fiber to add strength.  Once installed, the vegetated mats took root within two weeks.” – Brandon Buzzell, P.E., S.E.

Project construction was completed in early fall of 2017, by Dunnet Bay Construction of Glendale Heights, IL.  We look forward to future collaborations with the design and construction teams!
