Basement Tanking in Washington
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Basement Tanking in Washington is work we take on regularly, and the Tyne and Wear housing stock is a big part of why.
Most of what we see around Washington reflects the wider Tyne and Wear pattern — Tyneside flats, stone and brick terraces and postwar estates, and frost damage, driving rain and coastal salt at Whitley Bay and Tynemouth.
Local conditions bring cold with strong easterly exposure off the North Sea, and that has a direct bearing on which systems are worth specifying. Tyneside flats have an unusual shared-elevation arrangement that affects how a render job is scoped and quoted between two households.
When basement tanking is the right call. Choose tanking for cellar and basement conversions, persistently wet below-ground rooms, and any space you intend to make habitable.

FAQs
Basement Tanking in Washington
Are you insured?
Yes — full public liability cover, and we can send the certificate before we start. We are happy to provide RAMS for commercial and contractor work.
What areas do you cover?
We work UK-wide, with teams across England, Scotland, Wales and Northern Ireland. If we are not the right firm for your location we will tell you rather than waste your time.
What is the difference between Type A and Type C waterproofing?
Type A is a bonded barrier that keeps water out entirely. Type C accepts ingress, then drains and pumps it away behind a membrane. Type C is more forgiving of structural imperfections.
Does a tanked basement need a pump?
A Type C cavity drain system does — it relies on a sump and pump. A Type A barrier system does not, though a pump is sometimes added as a backup.
How much does rendering cost?
It is priced by the square metre and depends on the system, the condition of the walls and access. Our guide-price tool gives an indicative range in about a minute, and the survey turns that into a fixed written quote.
