Groundworks and foundations
Site set-out, trench-fill and raft foundations, ground beams, oversite slabs and below-ground drainage for new homes and commercial buildings.
Every great build starts below ground
Groundworks, excavation, drainage and civil engineering for housebuilders, developers and private clients across the UK. Set out to the millimetre, built to last, and finished to a standard you'll never need to revisit.
The part of every build no one sees, done better than anyone expects
Foundations, drainage and the ground beneath them are buried within weeks of being built. That's exactly why we take them so seriously.
Since 2024, Co-Construct has prepared the ground for more than 600 projects across the UK, from single luxury homes to 200-plot developments. Our own operatives run our own machines, and an engineer checks every level before the concrete arrives.

What we do
Six services, one accountable team. Most projects need several of them, so you deal with one contractor from the first dig to the final kerb.
Excavation and earthmoving
Site strips, bulk digs, cut and fill, trenching and muck-away, using our own excavators from 1.5 to 21 tonnes.
Drainage
Foul and surface water systems, soakaways, treatment plants, sewer connections and CCTV surveys, tested and signed off first time.
Civil engineering
Roads, car parks, kerbing, ducting and Section 278 and Section 38 highway works for developers and local authorities.
Basements and retaining walls
Basement dig-outs, temporary works and reinforced concrete walls for homes and sites where every metre counts.
Driveways and external works
Sub-bases, driveways, patios, swimming pool excavations and landscaping groundwork, finished to a standard that suits the house.
Groundworks anywhere in the UK
We're based near Stratford-upon-Avon, in the middle of the country, and our own teams and machines travel to sites across England, Scotland, Wales and Northern Ireland.
One contractor from first dig to final kerb, wherever your project is.
