Pipe Bedding 4/20 mm delivered in Liverpool
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 Liverpool and across Merseyside 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 and grab loads available across Merseyside within 24–72 hours. Wirral, Sefton, St Helens and Knowsley all covered, with bulk-bag drops for waterfront sites that have restricted manoeuvring space.

From Liverpool ONE's continued evolution to housing-led regeneration in Anfield, Everton and Bootle, our local customers are split between civil engineering, drainage and residential developers who need both material in and muck out.
What shapes Pipe Bedding 4/20 mm supply in Liverpool
Drainage packages on civil engineering, drainage and residential regeneration around Liverpool 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. Terraced regeneration streets alongside open dockland plots decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing material in and muck out on the same housing-led sites, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Birkenhead, Bootle and St Helens.
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 deliver across the Mersey Tunnels?
Yes — Wirral and Cheshire deliveries are routed through whichever tunnel suits the load and time window.
Material out as well as in, around Liverpool
Most deliveries into Liverpool 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.
