Pipe Bedding 4/20 mm delivered in Reading
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 Reading and across South East 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. Grab, tipper and HIAB loads across Reading, Bracknell, Slough and Newbury. Timed windows for town-centre and live commercial sites; skips for fit-out and refurbishment work.

Thames Valley sites are usually access-limited, so grab lorries and bulk bags do most of the work, with timed drops around town-centre restrictions.
What shapes Pipe Bedding 4/20 mm supply in Reading
Drainage packages on Thames Valley commercial and residential groundworks around Reading 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. Access-limited plots and timed town-centre drops decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing arisings loaded by grab where a tipper cannot get alongside, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Bracknell, Wokingham and Slough.
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 Slough and Maidenhead?
Yes, the whole Thames Valley corridor including Slough, Maidenhead, Bracknell and Basingstoke.
Material out as well as in, around Reading
Most deliveries into Reading 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.
