Filter Stone

Filter stone is a large, clean crushed stone ranging from 6" to 10", designed for drainage, filtration, and structural backfill. Its open size allows for maximum water flow while preventing soil movement, making it ideal for drainage-critical applications.

This stone does not compact, allowing consistent water passage and long-term performance in wet conditions.

Common applications for Filter Stone

• Drainage control around pipes, foundations, and trenches
• Sediment filtration in stormwater and wastewater systems
• Backfill for retaining walls to prevent water buildup
