Groundworks & Structural Work in Kent

Groundworks & Structural Work in Kent

Everything you eventually see is only as good as the ground beneath it. We handle the whole below ground stage — foundations, drainage, structural support and site levels — so every project starts on a base that will hold up for decades.

What we do

Everything this service covers

  • Digging out, marking out and levelling the site
  • All foundation types, from simple trenches to piles
  • Waste water and rainwater drainage
  • Structural steel and support
  • Concrete ground floors and damp protection
  • Retaining walls and levelling sloped sites
How we work

A clear process, start to finish

One team, accountable from the first drawing to the final finish.

01

Check the ground

We look at the soil, nearby trees and the weight the building will carry, so the foundation suits the site rather than a standard detail.

02

Dig & foundations

Trenches dug and concrete poured to the depth your building control inspector signs off on site.

03

Drainage & levels

Waste water and rainwater kept on separate runs, each laid at the right slope to carry water away.

04

Floor & prep

Damp protection and concrete floors, leaving a clean, level base to build on.

Good to know

Frequently asked questions

There is no fixed figure. It depends on the soil, any trees nearby and how much weight the building carries. Your building control inspector confirms the depth on site once the trench is open, and we dig to what they sign off.

If you build within 3 metres of a public sewer, or over one, you need written permission from your water company first — Southern Water or Thames Water across most of our area. It costs a few hundred pounds and takes a few weeks, so we sort it before we dig rather than after.

Yes. Foundations, drainage, structural support and site levels are all part of the same job for us, rather than several trades to chase.

Yes, though rain and frost affect concrete and make digging harder. We plan around the weather rather than fighting it.
