Pipe Bedding 4/10 mm delivered in Bristol
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 Bristol and across South West England 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. Tipper and grab loads delivered across Bristol, North Somerset and South Gloucestershire within 24–72 hours. Bulk-bag drops and timed windows arranged for Old City and harbourside sites with restricted access.

Bristol's pipeline is dominated by housing and infrastructure groundworks — sub-base, bedding stone and capping in, muck and hardcore out — with WAC testing needed on many of the city's former industrial plots.
What shapes Pipe Bedding 4/10 mm supply in Bristol
Drainage packages on housing and infrastructure groundworks around Bristol 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. Hill-side streets and phased housing parcels decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing made ground on ex-industrial plots that routinely needs WAC testing, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Bath, Weston-super-Mare and Clevedon.
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.
How quickly can you deliver into central Bristol?
Stocked aggregates and bedding usually land within 24–72 hours, with timed windows for harbourside and Old City sites booked a couple of days ahead.
Material out as well as in, around Bristol
Most deliveries into Bristol 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.
