Limestone #7

#7 limestone is a clean crushed stone made up of angular rock typically sized between 1/2 inch and 3/4 inch. Because it’s a consistent, washed material, it provides excellent drainage while still staying in place better than rounded gravel. That makes #7 limestone a popular choice for French drains, trench drainage, erosion control, and other water-management projects, while also working great for pathways, walkways, and decorative landscaping in garden beds and borders where you want a clean, finished look.
