Pipe Bedding 20 mm delivered in Wolverhampton
20 mm single size is a clean, high-void stone used for deep trench surround, soakaways and attenuation layers. With no fines it drains freely and does not slump into voids, so it is the default where the surround also has to store or convey water.
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.

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 20 mm supply in Wolverhampton
Drainage packages on brownfield remediation and redevelopment schemes around Wolverhampton take Pipe Bedding 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
What void ratio should I design a 20 mm stone soakaway to?
Clean 20 mm single size is commonly designed at around 30% void ratio, but your drainage engineer should confirm the figure for the material and compaction assumed in the calculation.
Is 20 mm single size the same as 20 mm ballast?
No. Ballast is an all-in mix of stone and sand for concrete. 20 mm single size is a washed, clean stone with the fines removed and is not a concreting material.
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.
