Rip Rap (Class A7)

Rip Rap in Class A7 Size Range

Rip Rap in the Class A7 size range is a large, durable aggregate commonly used for erosion control and shoreline stabilization. Produced from natural stone, Rip Rap is typically sourced from quarries and broken into angular pieces to ensure interlocking stability when placed. The Class A7 designation refers to a specific gradation, with stones generally ranging from 18 to 30 inches in diameter, making them ideal for heavy-duty applications.




The substantial size of Class A7 Rip Rap provides excellent resistance to displacement by water or wind, making it a preferred choice for protecting riverbanks, bridge abutments, culvert outlets, and coastal areas. Its angular shape helps the stones lock together, reducing movement and enhancing structural integrity. While its large size makes it less suitable for decorative or compacted surfaces, it excels in high-energy environments where maximum erosion protection is required. Both contractors and property owners rely on Class A7 Rip Rap for long-lasting, low-maintenance solutions in demanding conditions.
