6F5 Capping delivered in Manchester
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 Manchester and across Greater Manchester 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. Next-day tipper and grab availability across Greater Manchester on stocked lines. Bulk-bagged drops scheduled to suit confined city-centre sites, and two-way loads arranged where muck needs to come off before stone goes on.

What shapes 6F5 Capping supply in Manchester
Mixed urban fill across city-centre and inner-suburb plots is exactly why 6F5 Capping moves in volume around Manchester — it builds a working platform that takes plant and lorry traffic before any sub-base goes down. City-centre plots with limited storage space and phased delivery slots decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing demolition arisings and mixed muck off constrained regeneration plots, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Salford, Stockport and Bolton.
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.
Can you take muck away as well as deliver?
Yes — two-way loads are standard here. The lorry tips surplus soil or hardcore at a permitted facility and returns loaded with Type 1, bedding or topsoil, cutting both haulage and vehicle movements.
Material out as well as in, around Manchester
Most deliveries into Manchester 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.
