6F2 Capping delivered in Slough
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 Slough and across Berkshire 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. Stocked lines within 24–72 hours across SL postcodes. Artic and 8-wheel loads for trading-estate and Heathrow-corridor work with timed gate bookings; grab and bulk bags for town-centre plots.

Industrial and data-centre plots take volume Type 1 and capping to a strict daily tonnage, often with vehicle-booking systems and timed gate slots. Residential regeneration in the town centre is the opposite — tight plots, grab access and phased small loads. Made ground on former industrial land makes WAC classification routine.
What shapes 6F2 Capping supply in Slough
Made ground on former industrial plots is exactly why 6F2 Capping moves in volume around Slough — it builds a working platform that takes plant and lorry traffic before any sub-base goes down. Vehicle-booking systems and timed gate slots on data-centre and industrial plots decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing made ground that makes WAC classification routine before anything moves, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Windsor, Maidenhead and Uxbridge.
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 cover Windsor, Maidenhead and Uxbridge?
Yes — those and Staines, Iver, Langley and Burnham are on the same east Berkshire routes.
Material out as well as in, around Slough
Most deliveries into Slough 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.
