Basement Waterproofing in Newport
Expert basement waterproofing treatment for properties in Newport, Gwent. BS 8102-compliant — 10-year guarantee. Free surveys with no obligation.
Newport has a high proportion of older housing stock dating from the late Victorian and Edwardian periods, as well as post-war council and housing association properties — all of which are commonly affected by rising damp, condensation, and penetrating damp.
Basement Waterproofing Treatment in Newport
A wet or damp basement is a wasted opportunity. EverDry Damp specialises in BS 8102-compliant basement waterproofing systems that convert damp, unusable cellars into genuinely dry, habitable space. We use two primary approaches: Type A tanking (applied waterproofing systems bonded to the structure) and Type C cavity drain membranes (drainage systems that manage water rather than resist it). The right system depends on the water pressure, construction type, and intended use — we survey every basement before recommending a solution.
Newport is a city and major urban area in South Wales, with a mix of Victorian terraces, inter-war housing, and modern developments across the city. Our team covers Newport and the surrounding Gwent area regularly, and we understand the specific types of properties and damp challenges common in this part of South Wales.

Frequently Asked Questions — Basement Waterproofing in Newport
What is the difference between tanking and cavity drain membrane?
Tanking (Type A) applies a waterproof coating directly to the structure to resist water pressure. Cavity drain membrane (Type C) accepts that water will enter and manages it to a sump and pump instead. Type C is generally more reliable long-term for habitable spaces.
Can I convert my basement into a bedroom?
Basement conversions into habitable rooms require Building Regulations approval alongside proper waterproofing. We can advise on the waterproofing element and work alongside your architect or builder for the full conversion.
How long does basement waterproofing take?
A standard cellar waterproofing with cavity drain membrane typically takes 3–5 days depending on size. Larger or more complex projects may take longer. We will give you a precise programme before work starts.
