Bioengineering

A Green Solution

Soil bioengineering utilizes dormant cuttings of hardy, native plant material to stabilize soil. Structures are created to provide immediate mechanical stability while establishing a vigorous root matrix within the soil. The living structures have an inherent ability to become stronger with time. They will adjust or "self repair" in response to changes on the site.

Growth of the bioengineered material forms a healthy, natural groundcover of native plants, creating microclimatic conditions favorable to the establishment of other native plant species and wildlife habitat. Severe erosion necessitates immediate rehabilitation to alleviate public safety concerns and prevent further soil from entering the creek below.

The solution includes creation of a stable slope through soil bioengineering techniques, specifically brush layering. Ecological enhancement of the creek is implemented through development of a stable pool/riffle sequence, reinforced with fascines and a brush mattress.

Harrington McAvan Ltd. has been actively developing an expertise in soil bioengineering for over 30 years. In that time, the firm has researched, tested and implemented a wide variety of techniques to solve an equally wide range of problems, including river bank reinforcement, dry slope stabilization, stream management, marsh creation, shoreline protection and simple revegetation.

We have significant expertise in the selection of structures and plant materials appropriate to specific purposes, obtaining regulatory approvals, managing construction and monitoring installations.
