R4 Rip Rap

Max Delivery Capacity: 12 scoops per trip

Size Range: Typically 6"–12" in diameter. Approximately 25-35 stones per scoop.

This large rip rap stone is commonly used for heavy-duty erosion control, shoreline stabilization, drainage protection, and slope reinforcement. The oversized stone helps resist water movement and soil displacement in high-flow or erosion-prone areas while also providing a rugged natural appearance.

Common Uses

Erosion Control
Ideal for stabilizing shorelines, riverbanks, pond edges, and lake embankments where water movement can cause soil erosion and washout.

Drainage Structures
Frequently used to line drainage ditches, swales, culvert outlets, and stormwater discharge areas to reduce erosion and improve water flow management.

Slope & Embankment Protection
Helps reinforce steep slopes, embankments, and graded areas by minimizing soil movement and reducing the risk of slippage or washouts.

Geotextile & Underlayment Protection
Often installed over geotextile fabric to help protect underlying materials from erosion and environmental wear.

Road & Bridge Applications
Used around bridge abutments, roadway ditches, retaining structures, and roadside drainage areas where heavy stabilization is required.

Landscaping & Decorative Applications
Can also be used for decorative dry creek beds, retaining wall accents, natural borders, and large-scale landscape projects where a bold natural stone appearance is desired.
