Drainage Gravel 20mm

The heavy-duty drainage gravel built for high-flow applications and serious structural work.

When water management is the priority, 20mm drainage gravel delivers. The larger particle size creates more void space for water to move through freely, making it the go-to choice for retaining wall backfill, soak wells, trench drains and anywhere water pressure needs to be controlled fast.

It pulls double duty on driveways and pothole repairs too, compacting down into a firm, resilient surface that handles vehicle traffic without breaking down. Residential or commercial, this gravel earns its keep on site.
