Pipe Bedding 20 mm delivered in York
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 York and across North 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. Stocked lines within 24–72 hours across YO postcodes. Timed early-morning windows for city-centre and conservation-area drops; tipper and artic loads for fringe, village and commercial schemes.

Inside the walls, deliveries are timed, permitted and often grab or bulk-bag only. On the city fringe and at York Central it opens up to full loads and programmed earthworks. Flood-risk and archaeology conditions frequently dictate the sequence, so phased call-offs beat single bulk drops.
What shapes Pipe Bedding 20 mm supply in York
Drainage packages on walled-city work, York Central and city-fringe earthworks around York 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. Timed, permitted, often grab or bulk-bag only inside the walls decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing arisings sequenced around flood-risk and archaeology conditions, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Harrogate, Selby and Malton.
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.
Can you deliver inside York's city walls?
Yes — with timed, permitted windows and grab, HIAB or bulk-bag offload where a tipper cannot access or discharge.
Material out as well as in, around York
Most deliveries into York 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.
