Project Description

Anchored Wire Mesh System

We implemented an anchored wire mesh system to establish vegetation for steep slope repair, thus preventing erosion at the site. This system addresses the challenges that come with planting on a tall, eroded slope such as accessibility and the likelihood of seeds and plants washing away before they can establish roots. First we smoothed and prepped the eroded slope and sprayed it with a coating of mulch and grass seeds. Then we applied a plastic mesh to the slope and anchored it in place using large anchor pins that penetrate several feet into the slope. The mesh system holds the mulch and grass seed in place during the initial sprouting and growing period, obscured from view but remaining in place to supplement the natural erosion protection provided by the grass.
