Pipe Bedding 4/20 mm delivered in Wolverhampton
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 Wolverhampton 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. 24–72 hours on stocked lines across WV postcodes. 8-wheel tippers and grab lorries for tight urban plots, artic loads for larger industrial platforms, bulk bags where access is restricted.

- Attenuation and soakaway fill where void ratio matters
Former industrial land is the defining factor — made ground, contamination risk and remediation-led earthworks mean WAC testing and classification come first on many schemes. Recycled Type 1 and 6F5 capping are heavily used locally, often back-loaded on the same lorry that takes arisings away.
What shapes Pipe Bedding 4/20 mm supply in Wolverhampton
Drainage packages on brownfield remediation and redevelopment schemes around Wolverhampton 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. Remediation-led earthworks plots with sequenced movements decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing made ground where WAC testing and classification come first on many schemes, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Walsall, Dudley and Bilston.
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.
Which Black Country areas do you cover?
Wolverhampton, Walsall, Dudley, Bilston, Willenhall, West Bromwich and Cannock, plus Telford on the same routes.
Material out as well as in, around Wolverhampton
Most deliveries into Wolverhampton 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.
