Leeds
Leeds basement and cellar waterproofing questions often come down to the River Aire and the Leeds Flood Alleviation Scheme. Typical work here includes cellar tanking, cavity drain membranes, damp-proof courses and cellar conversions.

Ground and groundwater in Leeds
Leeds sits on Coal Measures sandstones and mudstones with river deposits along the Aire.
After Storm Eva flooded the city in December 2015, the Leeds Flood Alleviation Scheme added defences along the River Aire.
Weather, damp and flood history
Wet Yorkshire winters and summer storms drive cellar damp.
Water that reaches a foundation wall finds cracks, cold joints and the joint between wall and floor first, so the right fix depends on where the water is coming in and how high the groundwater rises.
Local authorities and codes
Leeds City Council and the Environment Agency run the Flood Alleviation Scheme.
In England, Approved Document C of the Building Regulations covers resistance to moisture, and BS 8102:2022 is the code of practice for protecting below-ground structures (Type A barrier, Type B structurally integral, Type C drained cavity). Basement conversions usually need Building Regulations approval and may need planning permission and a Party Wall agreement.
Typical basement and cellar work in Leeds
Cellar tanking, cavity drain membranes, damp-proof courses and cellar conversions. Every property is different, so the specialist inspects on site before recommending a system or giving a written quote.
Check the official flood map for your address, keep gutters and gullies clear, and photograph any water, damp patches, salts or cracks before the survey.
