Generally, for rocks loose slopes, common rockfall barrier will work. For surficially eroded slopes, the most effective method is slope vegetation, however, it certainly will cost a lot. A much more effective and economical measure for eroded slope surface is shotcrete. Concrete may help mass rocks support itself, reinforced wire mesh provides it with additional support to avoid slipping and failure. Therefore, direct shotcrete is allowed for common slope, but for higher degree of soil loss and steep slope, a wire mesh reinforced shotcrete becomes especially necessary.
Shotcrete is applied pneumatically, therefore the concrete material is extremely compacted against the surface to fill cracks and fissures and prevent loss soil and rocks from falling off. Therefore, shotcrete acts both as protective coating over the slope surface, but also as an anchoring surface onto which bolts, nails, anchors, hexagonal wire mesh netting could be fastened together. What's more, compared with slope vegetation, this wire mesh reinforced shotcrete will only take weeks or months to complete.
This shotcrete is a process of spraying concrete through hose at high velocity onto the surface. The shotcrete is popular in industry construction: retaining wall, underground tunneling... So, it also suits for slope to help it to achieve a high strength and support its stability. Slopes besides highways, railways, dams and embankment with steep slope, mass rocks, all could take this treatment.
