Pipe Bedding 4/20 mm delivered in Hull
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 Hull and across Yorkshire & the Humber 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. Tipper, grab and artic loads across Hull, Beverley, Goole and Grimsby, typically within 24–72 hours on stocked lines.

Typical uses on Hull sites
- Bedding and surround to 225 mm and larger drainage
- Deep trench work where haunch support is critical
- High-volume adopted sewer and highway drainage runs
- Attenuation and soakaway fill where void ratio matters
Low-lying ground and port-side hardstanding mean capping and free-draining granular fill are core, with artic tonnage for the larger energy and logistics platforms.
What shapes Pipe Bedding 4/20 mm supply in Hull
Drainage packages on port hardstanding, energy-corridor platforms and housing regeneration around Hull 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. Port estates with controlled vehicle movements plus open energy-corridor plots decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing wet clay arisings that need sheeting in transit and tip acceptance confirmed first, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Beverley, Goole and Grimsby.
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.
Do you cover North Lincolnshire?
Yes, Grimsby, Scunthorpe and the south bank are inside our Humber haulage network.
Material out as well as in, around Hull
Most deliveries into Hull 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.
