Building foundations engineered to last.

Strip, raft, trench-fill and pile foundations for extensions through to full developments, built to the highest standards and full compliance by our own crews and plant.

Building Foundations

The base every build stands on, set true and made to last.

SFS Groundworks is an owner-led firm with more than twenty years of experience in building foundations for both homes and commercial developments. We match the right foundation to the ground and the load, then deliver it to the highest standard, on time and on budget.

From a single home extension to a multi-phase development, we install strip, raft, trench-fill and pile foundations to your project requirements. Foundations carry the whole structure, so we build them to last and to full regulatory compliance, with a clean and considered finish.

Based in Tonbridge, Kent, we work nationwide for the right project. Get in touch for a free site survey and a clear, fixed quote.

Common questions

Building foundations, answered.

What types of building foundations do you install?
We install strip, raft, trench-fill and pile foundations. Strip foundations suit load-bearing walls on low to medium-rise homes, raft foundations spread the load across a reinforced slab, trench-fill is fast and effective with minimal excavation, and pile foundations stabilise structures on weaker ground.
How do you make sure foundations are built to last?
We build every foundation to the highest industry standards and to full regulatory compliance. We assess the ground first, match the right foundation type to the conditions and the load, then deliver the work with our own crews and plant so it is right the first time.
Do you handle the excavation and muck away as well?
Yes. Our diggers, excavators and dumpers handle the bulk excavation and muck away that goes with foundation work, removing soil, stone and surplus material from your site so the whole package stays with one team and the programme keeps moving.
Do you work nationwide?
We are based in Tonbridge, Kent and work most often across Kent, Sussex and Surrey, but we travel nationwide for the right project. If you are not sure whether we cover your area, just ask.
Are you fully insured and accredited?
Yes. We are CHAS Advanced accredited, CIWM members, first-aid trained, waste carrier licensed and fully insured, with more than 20 years on site.
