Pipe Bedding 4/10 mm delivered in Swindon
4/10 mm graded pipe bedding is the standard Class S bedding and surround stone for small-diameter drainage and utility runs. The tight 4–10 mm grading compacts readily around the pipe barrel without point-loading the crown, giving uniform support in narrow trenches where a larger single size would bridge.
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.

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 4/10 mm supply in Swindon
Drainage packages on logistics platforms and the Wichelstowe and Tadpole housing releases around Swindon take Pipe Bedding 4/10 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 4/10 mm suitable as Class S bedding?
Yes — 4/10 mm graded stone is one of the most commonly specified Class S bedding and surround materials for small-diameter pipe runs. Confirm the size against your drainage detail before ordering, as some specifications call for 10 mm or 4/20 mm instead.
How much pipe bedding do I need per metre of trench?
As a rule of thumb, a 450 mm wide trench with 100 mm bed and 150 mm cover over a 150 mm pipe takes roughly 0.25–0.30 tonnes per linear metre. Send us your trench dimensions and run length and we'll price the tonnage for you.
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.
