Brush Layering is the use of live branches buried horizontally in layers cut into the soil of a slope. The branch stock continues to grow and develops extensive roots to help stabilize the slope. Brush layering is a BioTechnical Solution used by Terrasol as a stand-alone solution, or in conjunction with other Erosion Control techniques.

Using living brush requires special storage, handling, and installation techniques and as such should be installed by trained erosion control specialists to achieve a properly stabilized slope.

Live stock materials can be harvested locally onsite or purchased from a plant propagation company. The stocks are usually 1 meter or more, however, 3/4 of the branch planted inside the slope. Branch materials should have live buds on them, ready to grow in the planting medium. For best success of a layered brush slope, using materials from various species and ages is recommended.

Terrasol has further recommendations for successful brush layering systems on your site than those listed above. We have been using and developing this technique to rehabilitate eroded and gullied slopes for decades and have assisted many companies from various resource development sectors to satisfy their environmental requirements placed on them by regulatory agencies.
