Pipe Bedding 20 mm delivered in Manchester
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 Manchester and across Greater Manchester 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. Next-day tipper and grab availability across Greater Manchester on stocked lines. Bulk-bagged drops scheduled to suit confined city-centre sites, and two-way loads arranged where muck needs to come off before stone goes on.

What shapes Pipe Bedding 20 mm supply in Manchester
Drainage packages on high-rise commercial, residential infill and civic schemes around Manchester 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. City-centre plots with limited storage space and phased delivery slots decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing demolition arisings and mixed muck off constrained regeneration plots, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Salford, Stockport and Bolton.
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.
Can you take muck away as well as deliver?
Yes — two-way loads are standard here. The lorry tips surplus soil or hardcore at a permitted facility and returns loaded with Type 1, bedding or topsoil, cutting both haulage and vehicle movements.
Material out as well as in, around Manchester
Most deliveries into Manchester 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.
