Pipe Bedding 4/10 mm delivered in Cambridge
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 Cambridge and across East of 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. Grab, tipper and HIAB loads across Cambridge, Ely, Huntingdon and Newmarket. Timed and out-of-hours windows for city-centre and campus sites.

Conservation-area access and college estates mean timed, low-disruption drops; the science-park and biomedical campus pipeline runs on bulk sub-base and drainage bedding.
What shapes Pipe Bedding 4/10 mm supply in Cambridge
Drainage packages on science-park, biomedical campus and college estate works around Cambridge 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. Conservation-area and college-estate drops needing timed, low-disruption windows decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing arisings off tightly controlled campus and college sites, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Ely, Huntingdon and St Neots.
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.
Can you deliver into conservation-area streets?
Yes — HIAB, bulk bags and manual offload cover sites where a tipper cannot discharge, with timed windows to limit disruption.
Material out as well as in, around Cambridge
Most deliveries into Cambridge 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.
