6F5 Capping delivered in Sheffield
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 Sheffield and across South Yorkshire 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. Direct from Yorkshire and Derbyshire quarries and recycling sites with short haulage runs into Sheffield. Tipper, grab and bulk-bag options across South Yorkshire, typically within 24–72 hours of order confirmation.

Local demand leans toward civils-grade sub-base and capping for the Advanced Manufacturing corridor, alongside drainage bedding for adoption schemes and muckaway for constrained city-fringe plots.
What shapes 6F5 Capping supply in Sheffield
Sloping city-fringe ground needing engineered platforms is exactly why 6F5 Capping moves in volume around Sheffield — it builds a working platform that takes plant and lorry traffic before any sub-base goes down. Constrained city-fringe plots with limited turning room decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing arisings off tight plots where there is nowhere to stockpile, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Rotherham, Barnsley and Doncaster.
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 Chesterfield and north Derbyshire?
Yes — anything within roughly 30 miles of Sheffield is routinely served from our South Yorkshire haulage network.
Material out as well as in, around Sheffield
Most deliveries into Sheffield 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.
