6F2 Capping delivered in Colchester
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 Colchester and across Essex 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. 24–72 hours on stocked lines across CO postcodes. 8-wheel tippers for estate work, artic loads for larger platforms, grab and bulk bags for constrained town-centre plots.

A lot of local work is residential-led drainage and estate roads, so bedding stone and Type 1 move in phased call-offs rather than single big drops. Archaeology-sensitive plots around the historic core need careful sequencing, and clay arisings usually require classification before disposal.
What shapes 6F2 Capping supply in Colchester
Essex clay across most of the district is exactly why 6F2 Capping moves in volume around Colchester — it builds a working platform that takes plant and lorry traffic before any sub-base goes down. Phased residential call-offs rather than single large drops decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing clay arisings that usually require classification before disposal, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Ipswich, Chelmsford and Clacton-on-Sea.
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 north Essex areas do you cover?
Colchester, Braintree, Witham, Halstead, Clacton and Sudbury, plus Chelmsford and Ipswich on the same routes.
Material out as well as in, around Colchester
Most deliveries into Colchester 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.
