Pipe Bedding 20 mm delivered in Warrington
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 Warrington and across Cheshire 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. Stocked lines within 24–72 hours across WA postcodes. Artic loads for motorway-corridor logistics platforms, 8-wheel tippers for estate roads, grab and bulk bags for constrained plots.

Distribution and industrial platforms drive volume capping and sub-base to a daily tonnage target, usually with booked gate slots. Housing releases at Omega and the town fringe take phased drainage and plot material. Peat and soft alluvial ground in places around the Mersey corridor makes working-platform design and capping choice important.
What shapes Pipe Bedding 20 mm supply in Warrington
Drainage packages on distribution platforms and the Omega and town-fringe housing releases around Warrington 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. Distribution platforms with booked gate slots and daily tonnage targets decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing arisings from platform construction and phased housing releases, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve St Helens, Widnes and Runcorn.
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 cover St Helens, Widnes and Runcorn?
Yes — those plus Northwich, Leigh, Altrincham and Chester are on our standard Cheshire and Merseyside routes.
Material out as well as in, around Warrington
Most deliveries into Warrington 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.
