6F5 Capping delivered in Stoke-on-Trent
6F5 is a coarse graded capping material to Specification for Highway Works Clause 613, used to build a working platform over weak subgrades before the sub-base goes down. On soft ground it is far more economical than importing extra Type 1, and it spreads and compacts into a stable layer that protects the formation through the wet.
Into Stoke-on-Trent and across West 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. Tipper, grab and artic loads across Stoke, Newcastle-under-Lyme, Stafford and Crewe within 24–72 hours on stocked lines.

Former industrial land means made ground, variable arisings and a real need for correct classification before disposal — followed by capping and sub-base to build a workable platform.
What shapes 6F5 Capping supply in Stoke-on-Trent
Former industrial ground with variable made ground throughout is exactly why 6F5 Capping moves in volume around Stoke-on-Trent — it builds a working platform that takes plant and lorry traffic before any sub-base goes down. Ex-industrial plots with wide but rough site access decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing variable arisings that genuinely need correct classification before disposal, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Newcastle-under-Lyme, Stafford and Crewe.
Questions we get asked
What is the difference between 6F5 and 6F2 capping?
Both are capping materials under SHW Clause 613. 6F5 is typically a coarser graded fill used where a thicker, robust platform is needed; 6F2 is the finer of the two gradings and is widely used as general capping fill. Follow your earthworks specification for which class is required.
How thick should a 6F5 capping layer be?
Thickness is a design decision based on subgrade CBR and the loading above — commonly 300–600 mm. Your geotechnical engineer should specify it; we supply the tonnage against the design.
Do you cover Cheshire as well?
Crewe, Congleton and southern Cheshire are inside our Stoke haulage radius.
Material out as well as in, around Stoke-on-Trent
Most deliveries into Stoke-on-Trent 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.
