Coarse, economical and quick to place, bulk filling and capping over soft ground before the engineered layers begin.
The 40mm grading of Class 4 is built for bulk: deep fills, capping over soft or wet subgrade, and the first lift on ground that won’t support finer material. The large top size bridges and stabilises where a 20mm product would simply disappear into the mud.
It’s the practical choice for early works, temporary access and any application where you need compactable volume at the lowest cost per cubic metre. Natural or recycled supply, scheduled to your earthworks program.
