Crusher Run vs Lava Rock
Side-by-side comparison of Crusher Run and Lava Rock to help you choose the right gravel for your project.
Overview
Dense blend of crushed stone and stone dust ranging from 1.5" down to fine particles. The fines fill voids between larger stones, creating a surface that self-compacts into an exceptionally firm, stable base. Crusher run is the most popular single-material solution for driveways and parking areas.
Lava rock is a lightweight, porous volcanic stone commonly used in landscaping. Its rough texture helps retain moisture while allowing airflow to plant roots.

Sizes & Colors
Crusher Run
Mix of angular crushed stone from 1.5" down to fine stone dust. The blend of sizes is what makes it self-compacting. Color is typically gray or blue-gray depending on source rock. Sometimes called "crusher run" because it's the raw output of a stone crusher.
Lava Rock
Typically 3/4"–1.5" sizes. Red or black.
