- 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
Is external or internal waterproofing better?
External stops water at the source but needs excavation; internal systems are often more practical.
How much does foundation waterproofing cost in Dublin?
Typically €3,000–€15,000. The exact price depends on access, the extent of the problem and whether parts or materials are needed.
How urgent is foundation waterproofing?
Assess before any extension or renovation.
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.
