Filled Rock Rolls are used as a flexible robust alternative to permanent revetments such as Rock Rip Rap or Gabion Baskets and Mattresses. They are ideal for erosion protection in high energy watercourses where a purely biodegradable approach would not be adequate. Used on their own, they form high strength, impact resistant scour protection. Working with the natural processes present in the watercourse, sediment will accumulate in the voids of the Rock Rolls delivering habitats for plants, insects and invertebrates within the river or stream.
