Pipe Bedding 4/10 mm delivered in Oxford
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 Oxford and across Oxfordshire 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 aggregates, bedding and topsoil are usually on site within 24–72 hours across OX postcodes. City-centre drops inside the bus-gate network are booked to a timed early-morning window; Harwell, Culham, Didcot and Bicester take full tipper or artic loads to your call-off dates.

Central Oxford work is dominated by restricted access — narrow college lanes, bus gates and conservation-area constraints mean grab and bulk-bag drops often beat an 8-wheel tipper. Out of town it flips: science-park and housing plots take full artic loads of Type 1 and capping against a call-off programme, with muckaway running back to licensed facilities in the same movement.
What shapes Pipe Bedding 4/10 mm supply in Oxford
Drainage packages on college estate work, science parks and housing plots around Oxford 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. Narrow college lanes, bus gates and conservation-area constraints in the centre decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing muckaway running back to licensed facilities on the same movement as delivery, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Abingdon, Bicester and Didcot.
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 inside Oxford's bus gates and conservation areas?
Yes. We schedule early-morning timed windows and use grab lorries, HIABs or bulk bags where an 8-wheel tipper cannot turn or discharge. Tell us the access constraint when you request a quote.
Material out as well as in, around Oxford
Most deliveries into Oxford 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.
