Superior Riprap

Superior riprap is comprised of roughly 6-30 inch boulders placed on woven fabric. The larger variation in boulder size offers more protection against wave action. Superior riprap can also be used to stabilize slopes in many instances because of the larger boulders used. This is our most popular type of riprap installation.
