Pipe Bedding 4/20 mm delivered in Colchester
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 Colchester and across Essex 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 CO postcodes. 8-wheel tippers for estate work, artic loads for larger platforms, grab and bulk bags for constrained town-centre plots.

- Deep trench work where haunch support is critical
- High-volume adopted sewer and highway drainage runs
- Attenuation and soakaway fill where void ratio matters
A lot of local work is residential-led drainage and estate roads, so bedding stone and Type 1 move in phased call-offs rather than single big drops. Archaeology-sensitive plots around the historic core need careful sequencing, and clay arisings usually require classification before disposal.
What shapes Pipe Bedding 4/20 mm supply in Colchester
Drainage packages on residential drainage, estate roads and archaeology-sensitive plots around Colchester 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. Phased residential call-offs rather than single large drops decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing clay arisings that usually require classification before disposal, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Ipswich, Chelmsford and Clacton-on-Sea.
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 north Essex areas do you cover?
Colchester, Braintree, Witham, Halstead, Clacton and Sudbury, plus Chelmsford and Ipswich on the same routes.
Material out as well as in, around Colchester
Most deliveries into Colchester 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.
