Pipe Bedding 20 mm delivered in Hull
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 Hull and across Yorkshire & the Humber 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, grab and artic loads across Hull, Beverley, Goole and Grimsby, typically within 24–72 hours on stocked lines.

Typical uses on Hull sites
- Deep trench pipe surround
- Soakaway and attenuation stone
- Free-draining backfill behind retaining structures
- Filter layers under geotextile-wrapped drainage
Low-lying ground and port-side hardstanding mean capping and free-draining granular fill are core, with artic tonnage for the larger energy and logistics platforms.
What shapes Pipe Bedding 20 mm supply in Hull
Drainage packages on port hardstanding, energy-corridor platforms and housing regeneration around Hull 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. Port estates with controlled vehicle movements plus open energy-corridor plots decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing wet clay arisings that need sheeting in transit and tip acceptance confirmed first, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Beverley, Goole and Grimsby.
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 North Lincolnshire?
Yes, Grimsby, Scunthorpe and the south bank are inside our Humber haulage network.
Material out as well as in, around Hull
Most deliveries into Hull 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.
