Best Gravel for Drainage Calgary

Choosing the right gravel for drainage is critical for Calgary landscape projects. The correct material allows water to move freely, reduces pressure behind retaining walls, and helps prevent long-term damage to your yard or foundation.

Why Drainage Gravel Matters

In Calgary, poor drainage can lead to water buildup, soil movement, and pressure against retaining walls or foundations. Using the correct gravel helps water flow away from structures and prevents costly repairs later.

Drainage gravel differs from base gravel because it does not contain fines, allowing water to pass through instead of becoming trapped.

Best Gravel Options for Drainage

Washed Rock

Washed rock is one of the best choices for drainage because it is free of fines and allows water to move easily through the material. It is commonly used behind retaining walls, around foundations, and in drainage zones.

40mm Gravel

40mm gravel is a larger stone size that works well for heavy drainage applications. Its size helps create larger gaps between stones, improving water flow in high-volume drainage areas.

Drainage rock is specifically selected for water control applications. It is commonly used in retaining wall systems, trench drainage, and foundation work where proper water movement is critical.

What Gravel NOT to Use for Drainage

Gravel that contains fines, such as road crush, should not be used for drainage applications. These materials compact tightly and block water movement, which can lead to buildup and pressure issues.
