Why It Matters

All groundwork signed off by Building Control. Full documentation for your records and future sales.
Mini excavators, dumpers, wacker plates, and laser levels. Right tools for precise results.

Poor drainage causes damp, subsidence, and failed Building Control. We design and install complete systems.
Crates or rubble soakaways sized to handle your roof area. No more standing water after rain.
Aco drains for driveways, patios, and garages. Prevents water ingress and surface pooling.
Section 106 agreements and water company connections handled. All paperwork and approvals included.

Groundworks covers all sub-structure and site preparation work: excavation, concrete footings and foundations, drainage systems, soakaways, retaining walls, and site levelling. Everything below ground level that supports the build above.
Foundation depth depends on soil type, tree proximity, and load requirements. Cambridgeshire's clay soils often require deeper trench-fill foundations—typically 1.0m to 2.5m. We work to structural engineer specifications and Building Control requirements on every project.
Yes. We install full drainage systems including surface water drainage, foul drainage, and soakaways. We also connect to existing mains drainage and ensure all work complies with Building Regulations and local water authority requirements.
We build retaining walls in brick, block, and concrete to engineer specifications. Whether you need a low garden wall or a tall structural retaining wall, we ensure proper foundations, drainage behind the wall, and long-term stability.
Site preparation typically takes 1–2 weeks for residential projects, depending on ground conditions, weather, and the scope of excavation and drainage work. We provide a clear timeline as part of your detailed quote.
