Foundation Services in Hampshire

Every successful building project starts with solid foundations. Dorrington Groundworks has been laying foundations across Hampshire, West Sussex, and Wiltshire for nearly 20 years, working with developers, builders, and homeowners to deliver substructures that stand the test of time.

We provide a comprehensive range of foundation and substructure services:

  • Strip Foundations: Traditional trench-fill and strip foundations for houses, extensions, and smaller structures
  • Raft Foundations: Engineered raft systems for challenging ground conditions and modern building methods
  • Piled Foundations: Coordination with piling contractors and construction of pile caps and ground beams
  • Retaining Walls: Reinforced concrete and blockwork retaining structures for level changes

As a SMAS accredited and CSCS certified contractor, we understand that foundations must be built precisely to engineer specifications. Our experienced team works to structural engineer details, coordinating with building control throughout Southampton and Hampshire to ensure every foundation meets the required standards. From initial excavation through to DPC level, we manage the complete substructure package.

Our family-run business has the expertise to handle ground conditions ranging from straightforward clay to complex made ground and high water tables. We carry out percolation tests, work with geotechnical reports, and adapt our approach to suit specific site conditions, ensuring your foundations are built right first time.
