Pipe Bedding 4/10 mm delivered in London
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 London and across Greater London 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. Same-week dispatch on stocked lines to all 32 boroughs and the City, with most orders on site within 24–72 hours. Tipper, grab, HIAB and bulk-bag options for restricted-access sites in Zones 1–2, plus night and weekend windows where daytime access is not practical.

London demands a supplier that understands logistics as well as materials. Most central drops are timed to 30-minute windows with grab or HIAB access, and our hauliers operate FORS Silver, ULEZ and DVS-compliant vehicles for schemes that require compliant transport. Muckaway is the other half of the job here — constrained sites need muck off before stone can come on.
What shapes Pipe Bedding 4/10 mm supply in London
Drainage packages on basement digs, borough highway packages and public-realm schemes around London 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. Timed 30-minute delivery windows, ULEZ and DVS-compliant vehicles and single-lane mews accesses decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing clay and made ground that usually needs classifying before a disposal route can be booked, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Croydon, Watford and Romford.
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 deliver inside the Congestion Charge zone?
Yes — we run ULEZ and DVS-compliant vehicles and coordinate Zone 1 drops around the 07:00–22:00 charging window, or schedule night deliveries for low-disruption sites.
Material out as well as in, around London
Most deliveries into London 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.
