Ballynahinch, Down
Basement Tanking in Ballynahinch
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Basement Tanking in Ballynahinch is work we take on regularly, and the Down housing stock is a big part of why.
Most of what we see around Ballynahinch reflects the wider Down pattern — stone and brick cottages, coastal villas and modern housing, and coastal salt and driving rain on exposed peninsula properties.
Ballynahinch sits in a part of the UK that gets wet with strong coastal exposure on the Ards peninsula — worth factoring into any render decision. 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 Ballynahinch
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.
