The largest drainage gravel in the range, built for maximum water flow where it matters most.

When water volume is high and drainage failure is not an option, 40mm drainage gravel is the answer. The large particle size creates wide void channels that move water rapidly through the profile, making it the top choice for retaining wall backfill where hydrostatic pressure needs to be relieved fast.

It also holds its ground on flood prone driveways and erosion control projects where smaller gravels wash out under heavy rainfall. If your site cop's a hammering when it rains, this is the gravel that stays put.
