Foundations & Underpinning in Swansea

Looking for foundations and underpinning in Swansea? S&K Property Investments & Improvement is a trusted local team covering Swansea and the surrounding area.

Every job starts with a free, no-obligation site survey and a clear, itemised price. Every solid build starts below ground. We dig and pour foundations for extensions and new builds, and carry out underpinning where existing foundations need strengthening — for example where a property has movement, subsidence, or where you're adding load with an extra storey. This is specialist work and we handle it with proper structural engineering and building-control sign-off.

Our foundations & underpinning service in Swansea includes

• Strip and trench-fill foundations
• Mass concrete and traditional underpinning
• Subsidence and movement remedial works
• Foundations for extensions and new builds
• Structural engineer's drawings arranged
• Building-control inspections managed

We work from engineer's drawings, manage building-control inspections at each stage, and keep you updated throughout. Underpinning is disruptive by nature, so we plan the sequence carefully to keep your property safe and the work moving.
