Pipe Bedding 4/10 mm delivered in Slough
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 Slough and across Berkshire 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 lines within 24–72 hours across SL postcodes. Artic and 8-wheel loads for trading-estate and Heathrow-corridor work with timed gate bookings; grab and bulk bags for town-centre plots.

- Narrow-trench work with limited compaction access
- Land drainage laterals and connections
Industrial and data-centre plots take volume Type 1 and capping to a strict daily tonnage, often with vehicle-booking systems and timed gate slots. Residential regeneration in the town centre is the opposite — tight plots, grab access and phased small loads. Made ground on former industrial land makes WAC classification routine.
What shapes Pipe Bedding 4/10 mm supply in Slough
Drainage packages on data-centre and industrial plots plus town-centre regeneration around Slough 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. Vehicle-booking systems and timed gate slots on data-centre and industrial plots decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing made ground that makes WAC classification routine before anything moves, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Windsor, Maidenhead and Uxbridge.
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 Windsor, Maidenhead and Uxbridge?
Yes — those and Staines, Iver, Langley and Burnham are on the same east Berkshire routes.
Material out as well as in, around Slough
Most deliveries into Slough 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.
