Pipe Bedding 4/20 mm delivered in York
4/20 mm graded bedding is the workhorse size for larger-diameter and deeper drainage. The wider grading gives strong interlock and good haunch support under 225 mm and above, and it places quickly in volume — which matters when a trench run is measured in hundreds of metres rather than tens.
Into York and across North Yorkshire 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 YO postcodes. Timed early-morning windows for city-centre and conservation-area drops; tipper and artic loads for fringe, village and commercial schemes.

Inside the walls, deliveries are timed, permitted and often grab or bulk-bag only. On the city fringe and at York Central it opens up to full loads and programmed earthworks. Flood-risk and archaeology conditions frequently dictate the sequence, so phased call-offs beat single bulk drops.
What shapes Pipe Bedding 4/20 mm supply in York
Drainage packages on walled-city work, York Central and city-fringe earthworks around York take Pipe Bedding 4/20 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, permitted, often grab or bulk-bag only inside the walls decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing arisings sequenced around flood-risk and archaeology conditions, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Harrogate, Selby and Malton.
Questions we get asked
Is 4/20 mm suitable for adopted sewers?
It is widely used for adopted drainage bedding and surround, but the size and class must match the adopting authority's detail and your engineer's specification. We can supply grading and test data to support submission.
Can you deliver 4/20 mm in artic loads?
Yes — for bulk civils programmes we deliver 28–29 tonne artic loads direct to site on a booked call-off schedule, which is the lowest cost per tonne where access allows.
Can you deliver inside York's city walls?
Yes — with timed, permitted windows and grab, HIAB or bulk-bag offload where a tipper cannot access or discharge.
Material out as well as in, around York
Most deliveries into York 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.
