Limestone Drainage Rock for Erosion Control, Foundation Backfill & Perimeter Drains

Thrifty Alberta’s premium-grade aggregate provides long-lasting support for drainage-heavy environments. Its angular composition allows water to pass through efficiently while helping prevent erosion and pressure buildup behind retaining walls or in trench systems.

This material is widely used in landscaping, road construction, and building foundations where water redirection and structural stability are key.
