6F2 Capping delivered in Northampton
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 Northampton and across East Midlands 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. Artic, 8-wheel tipper and grab availability across Northampton, Daventry, Wellingborough and Kettering. Bulk tonnage scheduled to a daily load target on earthworks packages.

What shapes 6F2 Capping supply in Northampton
Large-footprint platforms built up in capping layers is exactly why 6F2 Capping moves in volume around Northampton — it builds a working platform that takes plant and lorry traffic before any sub-base goes down. Open industrial plots taking artic tonnage decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing programmed muckaway with full duty-of-care paperwork per movement, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Daventry, Wellingborough and Kettering.
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.
Which parts of Northamptonshire do you cover?
Northampton, Daventry, Wellingborough, Kettering, Corby, Rushden and Towcester are all standard coverage, and the M1 and A14 corridors let us reach Milton Keynes, Bedford and Rugby on the same network.
Material out as well as in, around Northampton
Most deliveries into Northampton 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.
