Excavation, drainage, foundations and concrete bases. The part nobody sees, and the part that decides whether the rest lasts.

About This Service

Concrete and Groundworks in Hampshire

This is the part of a project nobody photographs and everything else depends on. Excavation, drainage, foundations and concrete bases — get these right and the patio, wall or building above them stays put. Get them wrong and no amount of quality on the surface will save it.

What we take on

  • Concrete bases for garden rooms, garages, workshops and sheds
  • Reinforced slabs where the load justifies mesh and extra depth
  • Foundations and footings for walls, extensions and outbuildings
  • Drainage — soakaways, land drains, channel drainage and surface water routing
  • Excavation, muck away and site levelling
  • Ducting for services run under new hard surfaces

Hampshire ground

The clay belt through Botley, Hedge End, Fair Oak and Bishopstoke swells in winter and shrinks in summer. That movement is what cracks under-specified slabs and lifts shallow foundations, and it is why we dig deeper on clay than the minimum would suggest. The chalk and greensand around Winchester and Bishops Waltham behave completely differently — more stable, faster draining, but with their own quirks where the two meet.

Drainage, before anything else

Most of the failures we get called to repair are drainage failures wearing another hat. Water pooling against a wall, running towards a house, or sitting under a patio will undo good work above it. Planning where water goes is the first conversation, not the last.

Frequently Asked Questions

The size of your concrete base should match the footprint of the structure plus at least 50–100mm overhang on each side. Thickness depends on load: a standard shed or garden room base should be a minimum of 100mm thick concrete on a 100mm compacted sub-base. For heavier structures such as garages, hot tubs or machinery, 150mm concrete on a 150mm sub-base with A193 reinforcement mesh is recommended. We will advise on the correct specification for your structure at the site visit.
In most cases, no. Concrete bases for sheds, garden rooms and outbuildings are generally permitted development provided the structure they support falls within permitted development limits (typically under 2.5m eaves height in a rear garden). If the structure is a garage or is positioned within 2 metres of a boundary, different rules apply. We will flag any potential planning issues at the quotation stage, but you should always verify with your local planning authority before proceeding.
C20 and C25 refer to the compressive strength of the concrete mix — C20 achieves 20 newtons per square millimetre and C25 achieves 25 N/mm² at 28 days. C20 is suitable for light-use bases such as garden paths and small shed bases. C25 is the standard specification for most residential concrete bases, driveways and foundations, offering better durability and resistance to surface wear. We use C25 concrete as standard on all bases we construct. For driveways subject to regular vehicle loading, C30 or above is recommended.
