Groundwork & Drainage in Finchley
Foundations, footings, excavation, drainage runs, soakaways and the proper preparation every good project starts with. We're a father-and-son team based in Buckinghamshire and Finchley is well within our regular working patch.
Groundwork & Drainage for homes in Finchley.
Looking for groundwork and drainage in Finchley? J.C General Builders is a family-run father-and-son team — James and Callum Weir — covering Finchley and the rest of London. The people who quote your job are the people who turn up and do it.
Groundwork is invisible once it's done, which is exactly why it's the first thing people are tempted to skimp on. We dig footings to the depth the ground actually needs, deal with clay heave and tree roots, and get drainage falls right the first time.
We take on standalone groundwork packages as well as the groundwork for our own extensions and landscaping — excavation, muck away, concrete, drainage, ducting and hardstanding.
The housing stock is mostly Victorian and Edwardian terraces plus 1930s semis, so we're usually dealing with London stock brick, side-return extensions, loft and kitchen refurbishments, small rear gardens re-laid in porcelain or reclaimed flags, and drainage that hasn't been touched in fifty years. Party Wall notices and Building Regs get sorted before the tools come out.

Ground assessment
We check soil type, water table, trees and existing services before pricing — no guessing at depths.
Set out and dig
Accurately set out and excavated, with spoil removed under waste transfer documentation.
Concrete and drainage
Poured, levelled and inspected, with drainage laid to fall, bedded and tested.
Backfill and hand-over
Compacted backfill, as-built notes and Building Control sign-off where the job requires it.
Groundwork & Drainage in Finchley — common questions
- How deep do foundations need to be?
- It depends on soil type and nearby trees — on Chiltern clay it's often considerably deeper than the standard minimum. We dig to what the ground and Building Control require.
- Can you fix a garden that floods?
- Usually yes. It's normally a mix of levels, compacted ground and no soakaway. We diagnose the cause rather than just adding a gully and hoping.
- Do you have machinery?
- Yes, we operate our own mini diggers and dumpers, and we bring in larger plant where access allows.
