6F2 Capping delivered in London
6F2 is a coarse recycled capping fill graded 0–125 mm, the most widely used capping material on UK earthworks. It builds a stable working platform over soft formations quickly and cheaply, and is the usual first import onto a site once the muckshift is under way.
Into London and across Greater London we supply it loose by tipper, by grab lorry where a stockpile has to be loaded or reached over a boundary, or in bulk bags for plots a lorry can't discharge into. Same-week dispatch on stocked lines to all 32 boroughs and the City, with most orders on site within 24–72 hours. Tipper, grab, HIAB and bulk-bag options for restricted-access sites in Zones 1–2, plus night and weekend windows where daytime access is not practical.

London demands a supplier that understands logistics as well as materials. Most central drops are timed to 30-minute windows with grab or HIAB access, and our hauliers operate FORS Silver, ULEZ and DVS-compliant vehicles for schemes that require compliant transport. Muckaway is the other half of the job here — constrained sites need muck off before stone can come on.
What shapes 6F2 Capping supply in London
London clay and deep made ground under most central plots is exactly why 6F2 Capping moves in volume around London — it builds a working platform that takes plant and lorry traffic before any sub-base goes down. Timed 30-minute delivery windows, ULEZ and DVS-compliant vehicles and single-lane mews accesses decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing clay and made ground that usually needs classifying before a disposal route can be booked, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Croydon, Watford and Romford.
Questions we get asked
Is 6F2 the same as crusher run or hardcore?
They overlap in practice but are not interchangeable on paper. 6F2 is a specified capping grading under Clause 613 with defined limits, whereas 'hardcore' is a generic term. If your spec names 6F2, order 6F2 and we'll supply the supporting data.
Can 6F2 be used as a sub-base?
No — 6F2 is a capping material. For sub-base use MOT Type 1 to Clause 803, or recycled Type 1 where secondary aggregate is permitted.
Do you deliver inside the Congestion Charge zone?
Yes — we run ULEZ and DVS-compliant vehicles and coordinate Zone 1 drops around the 07:00–22:00 charging window, or schedule night deliveries for low-disruption sites.
Material out as well as in, around London
Most deliveries into London pair with a removal: the lorry takes your arisings to a licensed facility and comes back loaded, so you pay for one movement rather than two.
