Rip Rap (Class 2, R-5)

Rip Rap in Class 2, R-5 Size Range

Rip Rap in the Class 2, R-5 size range is a large, durable stone aggregate commonly used for erosion control and shoreline stabilization. Produced by quarrying and breaking down larger rocks, these stones typically range from 9 to 18 inches in diameter, making them ideal for heavy-duty applications where significant protection against water or wind erosion is required.




The substantial size of Class 2, R-5 Rip Rap allows it to interlock effectively, creating a stable barrier that resists displacement from strong currents or waves. This makes it a preferred choice for lining riverbanks, protecting bridge abutments, reinforcing culverts, and stabilizing slopes. In residential settings, it is often used for decorative retaining walls or to prevent soil loss on steep grades. While its large size offers excellent durability and drainage, it can be challenging to install without heavy equipment and is not suitable for areas requiring a smooth or compacted surface.
