Pipe Bedding 4/20 mm delivered in Birmingham
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 Birmingham and across West Midlands 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 the West Midlands within 24–48 hours. Direct quarry haulage from the Midlands stone belt keeps loads efficient on bulk orders, and grab collections are timed around delivery slots for two-way running.

Our Birmingham customer base is heavily weighted toward civils and highways — Type 1 sub-base, 6F5 capping and certified pipe bedding make up the bulk of weekly volumes — with muckaway and WAC testing on the excavation side of the same jobs.
What shapes Pipe Bedding 4/20 mm supply in Birmingham
Drainage packages on civils and highways schemes plus adoption drainage around Birmingham 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. Highway working with lane closures and phased offloads decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing excavation arisings tested alongside the same civils packages they come from, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Solihull, Wolverhampton and Coventry.
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 the wider West Midlands?
Yes — Birmingham, Solihull, Wolverhampton, Coventry, Dudley, Walsall and West Bromwich are all served from our Midlands haulage network.
Material out as well as in, around Birmingham
Most deliveries into Birmingham 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.
