Pipe Bedding 20 mm delivered in Ipswich
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 Ipswich and across Suffolk 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. Stocked lines within 24–72 hours across IP postcodes. Artic and 8-wheel loads to port and industrial sites on timed bookings; tipper, grab and bulk bags for town and village work.

Port and industrial addresses need timed windows and vehicle-movement compliance; waterfront regeneration brings made ground that has to be classified before it can move. Housing and estate work inland is straightforward volume — sub-base, bedding and topsoil to a call-off programme.
What shapes Pipe Bedding 20 mm supply in Ipswich
Drainage packages on port, waterfront regeneration and inland housing around Ipswich 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. Port and industrial addresses needing timed windows and movement compliance decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing waterfront made ground that has to be classified before it can move, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Felixstowe, Woodbridge and Stowmarket.
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.
Do you deliver to Felixstowe and the port area?
Yes — Felixstowe, the Ipswich docks and surrounding industrial estates are on our standard Suffolk routes, with timed gate bookings where required.
Material out as well as in, around Ipswich
Most deliveries into Ipswich 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.
