What hot tub & swim spa bases in Weldon usually involve
A filled swim spa can weigh as much as several cars on a small footprint, so it needs a reinforced concrete slab built to the supplier's published requirements. We build the base, the drainage and the access so the unit can be craned or wheeled straight in.
Weldon is an old stone village on the east side of Corby, famous for Weldon stone, the limestone quarried here for centuries. Its historic centre of stone houses is surrounded by later estates that now join it to Corby.
We cover Weldon (NN17) and the villages around it, including Great Oakley, Little Oakley, Deene, Brigstock and Stanion.
Ground, drainage and conservation in Weldon
Weldon sits over the limestone and ironstone that were quarried here, and ground can change from natural rock to clay or fill within a garden. The Willow Brook runs past the village, so drainage needs designing rather than assuming.
Weldon has a conservation area covering the historic village, appraised in 2009. North Northamptonshire has no Article 4 direction in Weldon affecting driveways, porches or extensions.
The Willow Brook runs past Weldon, where the Environment Agency operates the Weldon flood storage reservoir. You can check any address on the Environment Agency flood map.
