6F5 Capping delivered in Liverpool
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 Liverpool and across Merseyside 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 and grab loads available across Merseyside within 24–72 hours. Wirral, Sefton, St Helens and Knowsley all covered, with bulk-bag drops for waterfront sites that have restricted manoeuvring space.

From Liverpool ONE's continued evolution to housing-led regeneration in Anfield, Everton and Bootle, our local customers are split between civil engineering, drainage and residential developers who need both material in and muck out.
What shapes 6F5 Capping supply in Liverpool
Dock-side fill and older urban made ground is exactly why 6F5 Capping moves in volume around Liverpool — it builds a working platform that takes plant and lorry traffic before any sub-base goes down. Terraced regeneration streets alongside open dockland plots decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing material in and muck out on the same housing-led sites, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Birkenhead, Bootle and St Helens.
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 deliver across the Mersey Tunnels?
Yes — Wirral and Cheshire deliveries are routed through whichever tunnel suits the load and time window.
Material out as well as in, around Liverpool
Most deliveries into Liverpool 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.
