20mm Gravel Bulk Bag | Bulk Bag Gravel | Turnbull

Our 20mm gravel bulk bag is a versatile aggregate suitable for driveways, drainage, landscaping, and general construction. Supplied in a large 850kg bulk bag, this gravel provides a practical and cost effective way to buy gravel in bulk for landscaping, driveway, and drainage projects.

This 10–20mm graded gravel is a natural mix of brown, white, and grey stones with a combination of flat and angular shapes. The angular structure helps the gravel compact and lock together, making it particularly suitable for driveways and paths, while still allowing excellent drainage.

20mm gravel is one of the most commonly used sizes of driveway and landscaping gravel in the UK, offering a durable, free draining surface that works well for both decorative and practical applications.

Buying gravel in a bulk bag is far more convenient than purchasing multiple smaller bags, reducing packaging waste, handling time, and overall cost.
