- 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

- Area and depth of the space
- Water pressure and whether a sump pump is needed

Frequently Asked Questions
Do I need planning permission for a basement conversion?
Converting an existing basement may not, but changes to a protected structure or new openings may. Check with your council.
How much does basement conversion waterproofing cost in Dublin?
Typically €15,000–€50,000, depending on the size of the house, access and specification.
How do I choose a contractor for basement conversion waterproofing?
Get at least two itemised written quotes, ask to see recent similar work, and check registrations, insurance and guarantees.
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.
