Pipe Bedding 20 mm delivered in Peterborough
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 Peterborough and across Cambridgeshire 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 are typically delivered within 24–72 hours across PE postcodes. Artic and 8-wheel tipper loads for volume earthworks on the A1/A47 corridors; grab and bulk bags for restricted plots in the city centre and older suburbs.

Typical uses on Peterborough sites
- Deep trench pipe surround
- Soakaway and attenuation stone
- Free-draining backfill behind retaining structures
- Filter layers under geotextile-wrapped drainage
Fen-edge ground conditions push a lot of Peterborough work towards capping and geotextile working platforms before any sub-base goes down, so 6F5 and 6F2 move in volume here. Plot-scale drainage packages take bedding stone in daily call-offs, and land-drainage and soil-import work draws on BS3882 topsoil through the growing season.
What shapes Pipe Bedding 20 mm supply in Peterborough
Drainage packages on fen-edge housing, drainage packages and land drainage around Peterborough 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. Open fen plots with daily call-off drainage packages decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing arisings from plot-scale drainage and soil-import work, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Wisbech, Stamford and Huntingdon.
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 deliver into the Fens as well as Peterborough itself?
Yes — Wisbech, March, Whittlesey, Spalding and the surrounding villages are on our standard Peterborough routes.
Material out as well as in, around Peterborough
Most deliveries into Peterborough 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.
