Pipe Bedding 4/20 mm delivered in Peterborough
4/20 mm graded bedding is the workhorse size for larger-diameter and deeper drainage. The wider grading gives strong interlock and good haunch support under 225 mm and above, and it places quickly in volume — which matters when a trench run is measured in hundreds of metres rather than tens.
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.

- High-volume adopted sewer and highway drainage runs
- Attenuation and soakaway fill where void ratio matters
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 4/20 mm supply in Peterborough
Drainage packages on fen-edge housing, drainage packages and land drainage around Peterborough take Pipe Bedding 4/20 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
Is 4/20 mm suitable for adopted sewers?
It is widely used for adopted drainage bedding and surround, but the size and class must match the adopting authority's detail and your engineer's specification. We can supply grading and test data to support submission.
Can you deliver 4/20 mm in artic loads?
Yes — for bulk civils programmes we deliver 28–29 tonne artic loads direct to site on a booked call-off schedule, which is the lowest cost per tonne where access allows.
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.
