Basement and cellar waterproofing across United Kingdom
Below-ground rooms sit in damp ground all year. Water finds its way through mortar joints, cracks and the junction between wall and floor, and older cellars were rarely built to keep it out. UK Basement Waterproofing focuses on finding where the water is coming from and choosing the right protection under BS 8102 — in London, Manchester, Birmingham, Leeds and throughout United Kingdom.
Some cellars need a cementitious tanking system, others a drained cavity membrane with a sump; many need both, plus attention to gutters, ground levels and drainage outside.
Straight answers on cost
Costs depend on the size of the basement, the cause of the water, access and the system chosen, and we explain them after the inspection. Our cost guide lists the factors that drive the price.
