Homes in Dún Laoghaire & South Coast and what that means for waterproofing
Victorian terraces and large granite and brick villas in Monkstown, Dún Laoghaire, Dalkey and Killiney, with mid-century homes around Blackrock and Booterstown. Sea exposure is high along the whole stretch.
Period homes often have basements or lower ground floors in solid masonry with no original waterproofing, so converting them to living space needs a full below-ground system. Exposed coastal walls face wind-driven rain, and properties near the shoreline can have higher groundwater levels. 1930s–1960s homes rarely have basements but often have leaking flat roofs over later extensions and older, failing shower trays.
What to check before you hire a waterproofing specialist
- Ask which BS 8102 approach will be used and why
- Ask whether the system includes a sump and pump, and what happens in a power cut
- Get the guarantee in writing, ideally insurance-backed for larger jobs
- For showers and wet rooms, ask what tanking system is used under the tiles
- Check that surface water and gutters have been ruled out first

Frequently Asked Questions
Do you cover Blackrock, Booterstown, Monkstown, Dún Laoghaire, Dalkey and Killiney?
Yes. Dún Laoghaire & South Coast includes Blackrock, Booterstown, Monkstown, Dún Laoghaire, Dalkey and Killiney. If you are just outside these areas, get in touch anyway.
What waterproofing issues are common in Dún Laoghaire & South Coast?
Period homes often have basements or lower ground floors in solid masonry with no original waterproofing, so converting them to living space needs a full below-ground system. Exposed coastal walls face wind-driven rain, and properties near the shoreline can have higher groundwater levels. 1930s–1960s homes rarely have basements but often have leaking flat roofs over later extensions and older, failing shower trays.
What is the difference between damp-proofing and waterproofing?
Damp-proofing resists moisture. Waterproofing resists water under pressure, as in basements below ground level.
Do I need a sump pump?
If the system collects water, like a cavity drain membrane, a sump pump removes it. A battery backup is recommended.
Can a shower leak without me seeing it?
Yes. Water can get through grout and failed seals into the floor or wall for months before you see stains.
Is waterproofing guaranteed?
Reputable installers give written guarantees. For basements, ask about insurance-backed guarantees.
