Basement Tanking in Holywood
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Our basement tanking work in Holywood starts with a free survey, because guessing at a render specification is how jobs go wrong.
Across Down, stone and brick cottages, coastal villas and modern housing dominates, and coastal salt and driving rain on exposed peninsula properties is what we are called out to most often.
Local conditions bring wet with strong coastal exposure on the Ards peninsula, and that has a direct bearing on which systems are worth specifying. The ards peninsula is exposed on both sides, so properties there weather from multiple aspects rather than one prevailing direction.
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 Holywood
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.
Do you offer a guarantee?
Yes. Every job carries our workmanship guarantee, and where a full manufacturer-specified system is installed you also get the system warranty on top.
