How waterproofing jobs should be done
Waterproofing is about stopping water where it enters, or managing it so it can't do damage. Below-ground work in Ireland generally follows BS 8102, which describes three approaches: barrier protection (tanking), structurally integral protection and drained protection (cavity drain membranes). The right choice depends on the water pressure and how the space will be used.
What usually affects the price:
- Area and depth of the space
- Water pressure and whether a sump pump is needed
- Preparation, including removing old plaster or finishes
- Access
- The finish required afterwards
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
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.
How much does a waterproofing specialist cost in Dublin?
It depends on the job. Our waterproofing cost guide lists typical Dublin prices for each service, from €5,000–€25,000 for basement waterproofing upwards.
