    Rock Size: There are two options for rocks – SelfLaunching / SelfFiltering Rock or standard riprap The advantage of SelfLaunching / SelfFiltering rock is that the revetment will build its own toe, by selflaunching, in any scour hole that forms In addition, the different sizes of rock act as their own filter medium, so no filter fabric or filter gravel is needed This decreases cost
