A slope at the side of a major road in Al Bahah, Saudi Arabia was posing a risk to road users.
The substrate was easily loosened by rainfall and was therefore at risk of causing rocks to fall away. With the slope's close proximity to the road, this was becoming dangerous and could also damage the road surface.
In order to prevent this happening, CC was specified to protect the slope from erosion. Shotcrete had been considered, but would have been more time consuming and more costly for the client. CC also required significantly less vehicle movements on site and would not need specialist labour or heavy plant.
