Riprap, also known as rip rap, rip-rap, shot rock, rock armour or rubble, is rock or other material used to armor shorelines, streambeds, bridge abutments, pilings and other shoreline structures against scour and water or ice erosion.
The best rip rap is comprised of granite, gneiss, sandstone or trap rock. These hard stones can handle whatever Mother Nature throws their way. In addition to considering the stones used to manufacture rip rap, you should also take a look at the supplierâs inventory.
