Groundworks & garden walls in Somerset

The hard work that makes a garden or driveway last — excavation, retaining walls, drainage and bases.

Sleeper terraces with clean stone and decorative gravel in Nempnett Thrubwell

Good groundwork is invisible when it is done well. We excavate and reshape ground by machine or, where access is tight, by hand — we have hand-dug 30 tonnes of soil for a single patio extension and excavated almost 60 tonnes to turn a sloping garden into usable tiers.

We build retaining walls in block, rough stone, Cotswold and tumbled walling, railway sleeper terraces and steps, and we solve drainage problems with land drains, ACO channels and soakaways.

We also lay concrete bases for sheds, log cabins and garden offices. For tired old walls, Wallcrete — a lightweight render stamped with the pattern and colour of your choice — is a cost-effective way of making old walling look new without demolishing and rebuilding in expensive stone.

Highly recommend

Jack did a brilliant job of building terraces in our sloped garden. He even reused the original stones, that we had from our demolished kitchen walls, to build new retaining walls in the garden. By doing this it has tied the garden into the house…

Questions

Frequently asked questions

Can you work where there is no machine access?

Yes. We have completed several projects where all the excavation was done by hand because of tight or difficult access.

My garden floods — can you help?

Yes. We install land drains, gravel traps and soakaways to take water away from lawns and patios, and channel drains to protect thresholds.

Do you build bases for garden buildings?

Yes, we lay concrete bases for sheds, Dutch barns, log cabins and garden offices, and can supply and build the building too.
