Limestone riprap is made of coarse limestone boulders and is used to prevent soil erosion due to water. Riprap can be used on banks and shores to create a rock slope into the water. This prevents the water from eroding away into the land. Use our rip rap along waterways, beaches, or rivers to prevent the waterline from further receding. Also they make great accents for your landscape project or can be used as barriers where you don’t want traffic.
