Damp Proofing in Henley-on-Thames

Henley-on-Thames sits low on the river bend, and that proximity to the Thames defines the damp risks we most often diagnose in the town. Cellars and basements along New Street, Hart Street, and Riverside frequently flood or stay perpetually wet — these properties need cementitious tanking or cavity-drain membrane systems to be habitable below ground. The Georgian and Victorian terraces that line the town centre were built before modern damp-proof courses and can show rising damp where decades of pavement build-ups have raised external ground levels above the original DPC. AP Damp Solutions has extensive experience with Thames-side period properties and basements across South Oxfordshire and the Chilterns.

Henley basements are a specialism, not a sideline — we install both Type A (tanking) and Type C (cavity-drain) waterproofing systems with the design rigour BS 8102 demands. Our professional damp surveys distinguish flood ingress from rising damp from lateral penetration so the right system goes in first time. Every remedial installation carries long term written guarantees and we work routinely with conservation-area and listed-building constraints.
