Pipe Bedding 20 mm delivered in Liverpool
20 mm single size is a clean, high-void stone used for deep trench surround, soakaways and attenuation layers. With no fines it drains freely and does not slump into voids, so it is the default where the surround also has to store or convey water.
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 Pipe Bedding 20 mm supply in Liverpool
Drainage packages on civil engineering, drainage and residential regeneration around Liverpool take Pipe Bedding 20 mm in daily call-offs rather than one bulk drop, so bedding lands as each run is dug rather than sitting in the way. 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 void ratio should I design a 20 mm stone soakaway to?
Clean 20 mm single size is commonly designed at around 30% void ratio, but your drainage engineer should confirm the figure for the material and compaction assumed in the calculation.
Is 20 mm single size the same as 20 mm ballast?
No. Ballast is an all-in mix of stone and sand for concrete. 20 mm single size is a washed, clean stone with the fines removed and is not a concreting material.
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.
