Crushed Limestone vs Lava Rock
Side-by-side comparison of Crushed Limestone and Lava Rock to help you choose the right gravel for your project.
Overview
Crushed sedimentary rock with a pale gray to white color. Compacts well and provides good drainage. Limestone is a popular choice in the Midwest and South where it's quarried locally, keeping costs low.
