6F2 Capping delivered in Ipswich
6F2 is a coarse recycled capping fill graded 0–125 mm, the most widely used capping material on UK earthworks. It builds a stable working platform over soft formations quickly and cheaply, and is the usual first import onto a site once the muckshift is under way.
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 6F2 Capping supply in Ipswich
Waterfront made ground and firmer inland estate plots is exactly why 6F2 Capping moves in volume around Ipswich — it builds a working platform that takes plant and lorry traffic before any sub-base goes down. 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
Is 6F2 the same as crusher run or hardcore?
They overlap in practice but are not interchangeable on paper. 6F2 is a specified capping grading under Clause 613 with defined limits, whereas 'hardcore' is a generic term. If your spec names 6F2, order 6F2 and we'll supply the supporting data.
Can 6F2 be used as a sub-base?
No — 6F2 is a capping material. For sub-base use MOT Type 1 to Clause 803, or recycled Type 1 where secondary aggregate is permitted.
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.
