Pipe Bedding 4/20 mm delivered in Coventry
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 Coventry 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, grab and artic loads across Coventry, Nuneaton and Warwickshire, usually within 24–72 hours on stocked lines. Two-way loads available so muck goes off and stone comes back on one visit.

Most Coventry work is civils and industrial: capping and sub-base for large slabs and yards, pipe bedding for drainage runs, and programmed muckaway off constrained inner-ring-road sites.
What shapes Pipe Bedding 4/20 mm supply in Coventry
Drainage packages on civils and industrial slab and yard construction around Coventry 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. Constrained inner-ring-road sites with programmed movements decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing programmed muckaway off tight inner-city plots, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Nuneaton, Rugby and Bedworth.
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 Warwickshire as well as Coventry?
Yes — Nuneaton, Bedworth, Rugby, Leamington and Warwick are all inside our standard Coventry haulage radius.
Material out as well as in, around Coventry
Most deliveries into Coventry 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.
