Pipe Bedding 4/20 mm delivered in Swindon
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 Swindon and across Wiltshire 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. 24–72 hours on stocked lines across SN postcodes. Bulk artic loads for M4-corridor sites, 8-wheel tippers for estate roads, grab and bulk bags where plot access is tight.

- Attenuation and soakaway fill where void ratio matters
Large flat-site logistics work drives volume Type 1 and capping in artic loads, while the housing releases at Wichelstowe, Tadpole Garden Village and the eastern villages take phased plot-by-plot bedding, sand and topsoil. Clay arisings from the Vale mean classification and muckaway planning matter before earthworks start.
What shapes Pipe Bedding 4/20 mm supply in Swindon
Drainage packages on logistics platforms and the Wichelstowe and Tadpole housing releases around Swindon 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. Large flat logistics plots taking artic loads, plus phased plot-by-plot housing drops decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing clay arisings where classification and planning matter before earthworks start, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Chippenham, Cirencester and Marlborough.
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 cover north Wiltshire and the Cotswold edge?
Yes — Chippenham, Calne, Cirencester, Marlborough and the surrounding villages run on the same Swindon haulage routes.
Material out as well as in, around Swindon
Most deliveries into Swindon 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.
