Drain Rock, also known as washed gravel, is a clean stone material designed for maximum drainage. The stones are washed to remove fines, allowing water to flow freely through the material.

This gravel is commonly used for French drains, retaining wall backfill, pipe trenches, and foundation drainage. Its open structure prevents water buildup while maintaining long-term performance in outdoor environments.

Widely used across California, drain rock is essential for landscape and construction projects that require reliable drainage and moisture control.
