Pipe Bedding 20 mm delivered in Sheffield
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 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 Pipe Bedding 20 mm supply in Sheffield
Drainage packages on the Advanced Manufacturing corridor and adoption drainage schemes around Sheffield 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. 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 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 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.
