Concrete for Summerhouse Bases

Order online, delivered across the Midlands, often next day.

From £212.66 per m³ (ex VAT)

A summerhouse needs a level, stable base that won't move with the seasons. C28/35 ready-mix at 100mm depth on a compacted Type 1 sub-base is the recommended spec for any summerhouse with seating, glazing or basic electrics. A typical 3×3m summerhouse base needs ~0.9m³; a 4×3m base needs ~1.2m³. Our calculator includes 10% wastage automatically.

Recommended Mix C28/35
  • C28/35 high-strength mix, won't crack or settle
  • 100mm recommended depth on compacted sub-base
  • Suitable for summerhouses, gazebos and timber garden buildings
  • 1m³ minimum, no small-load surcharge
  • Volumetric mixers: only pay for what's poured
