What hot tub & swim spa bases in Market Harborough 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.
Market Harborough has a historic core around the Square and the Old Grammar School, Victorian and Edwardian streets out to Little Bowden and Great Bowden, later estates around the edge, and the large Airfield Farm development near Lubenham.
We cover Market Harborough (LE16) and the villages around it, including Great Bowden, Little Bowden, Lubenham, Foxton, East Farndon, Kibworth, Husbands Bosworth and Medbourne.
Ground, drainage and conservation in Market Harborough
Market Harborough is on Jurassic mudstones and clays, which drain slowly, and the town sits where the River Welland meets the River Jordan. Water management decides most designs here, so we test the ground before choosing a soakaway or a permeable build-up.
The Market Harborough conservation area covers the historic town core and was designated in 1969, with separate conservation areas at Great Bowden and Lubenham. An Article 4 direction served in 2020 on land at Queen's Street, Little Bowden, covers gates, fences and walls.
The town centre flooded from surface water in September 2024, when a high River Welland stopped the drains discharging, and more than 50 properties flooded in July 2013. Permeable surfaces and attenuation are worth taking seriously here. You can check any address on the Environment Agency flood map.
