Pipe Bedding 20 mm delivered in Bedford
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 Bedford and across Bedfordshire 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 material is usually on site within 24–72 hours across MK40–MK45 postcodes. Artic loads on A421 warehouse sites, 8-wheel tippers and grab lorries for estate and infill work.

Growth-arc housing here means drainage-led programmes: bedding stone in daily call-offs, sub-base for estate roads and topsoil for plot finishing. Riverside and floodplain sites near the Great Ouse need careful classification of arisings before muckaway, and capping is common where alluvial ground is soft.
What shapes Pipe Bedding 20 mm supply in Bedford
Drainage packages on growth-arc housing, estate roads and plot finishing around Bedford 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. Growth-arc housing plots on rolling drainage-led programmes decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing riverside and floodplain arisings needing careful classification before muckaway, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Kempston, Milton Keynes and Biggleswade.
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.
Which postcodes do you serve from Bedford?
MK40 to MK45 and the surrounding villages, plus Biggleswade, Sandy, St Neots and Rushden on the same routes.
Material out as well as in, around Bedford
Most deliveries into Bedford 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.
