Pipe Bedding 20 mm delivered in Leeds
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 Leeds and across West 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. Short haulage routes from Yorkshire quarries and recycling facilities keep lead times tight — most stocked lines land within 24–72 hours. Tipper, grab and bulk-bag options across West and South Yorkshire.

What shapes Pipe Bedding 20 mm supply in Leeds
Drainage packages on regeneration plots, adoption drainage and market-town housing around Leeds 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. Part-built estate roads and city-fringe plots with staged access decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing muck that has to leave before base can go down, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Bradford, Wakefield and Huddersfield.
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.
How quickly can you get bedding stone to a Leeds site?
Stocked bedding sizes are usually on site within 24–48 hours, and same-day is often possible for orders placed early in the day.
Material out as well as in, around Leeds
Most deliveries into Leeds 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.
