Professional Greenhouse Base Installation in Poole. Built for Drainage. Guaranteed 10 Years.

Poole sits on the eastern rim of the Poole Basin, a formation of Eocene sands and Plateau Gravel deposits. Near the Harbour — Sandbanks, Lilliput, and Hamworthy — the soil is predominantly fine sand with good drainage. Inland at Broadstone and Upper Parkstone, you'll encounter heavier sandy clay with gravel inclusions. Both soil types require a properly compacted sub-base to prevent the greenhouse from settling unevenly. We adjust our preparation depth depending on the specific geology of your plot.

Poole's sandy soils generally drain well, making waterlogging inside greenhouses rare. We incorporate a 5mm fall across the base to shed surface water and prevent puddles forming underfoot. In lower-lying areas near the Harbour — particularly Hamworthy and parts of Upton — localised water pooling can occur after prolonged rainfall. Here, we may recommend perimeter drainage channels to direct excess water away from the greenhouse footprint.

Properties around the Harbour, Sandbanks, and the open waterfront at Hamworthy are exposed to south-westerly winds. A greenhouse base must be properly anchored to prevent wind lift — we bolt the frame directly to the base or use ground screw fixings designed to resist uplift forces. Inland gardens in Canford Cliffs and Branksome Park benefit from shelter provided by mature pine canopy, though individual gusts can funnel through gaps between buildings.

Poole enjoys a mild maritime climate moderated by the Harbour and the English Channel. Frost is relatively uncommon at lower elevations, and the growing season extends noticeably longer than inland Dorset. Elevated gardens in Broadstone and Upper Parkstone sit higher and may experience slightly more frost, particularly in sheltered dips. Overall, Poole is an excellent location for year-round greenhouse growing.
