This is a great video by Vermont DOT that describes how scaling is used as part of their mitigation efforts for rockfall. If you have never seen how high scaling works, this gives you a good perspective. Scalers use ropes to access the slope and work from the top down to test rocks with prybars and other tools to see if they are loose, bringing them down if they are. They also use airbags, pneumatic “pillows” that start flat and can slide into cracks and joints and be inflated using compressed air to push rocks off the slope.

More videos! French Company G.T.S. has posted some great videos on rockfall protection systems on their YouTube channel. I don’t speak French, so I can’t give you any more info on the company (although their website looks like it has plenty of info!).
