Damp and moisture service

Basement and cellar waterproofing

We assess water pressure, drainage and how the space will be used before choosing a waterproofing system for a basement or cellar.

When to call

Signs worth having checked.

  • Wet cellar walls
  • Water at wall-floor junctions
  • Salt deposits below ground
  • Recurring leaks after rainfall
  • A planned cellar conversion
Worth knowing: Basement waterproofing is a system, not a single coating. Drainage, maintenance and what happens if a component fails all need to be considered.
How we assess it

The symptom is the starting point.

The same mark can have several causes. We use your description to prepare, then inspect the property before recommending work.

What does a survey include?
What we look at

Checks that put the symptoms in context.

  • Where water is entering and the pressure involved
  • Wall and floor construction
  • Drainage, sump and pump options
  • Ventilation and the intended use of the room
  • Access for maintenance and future inspection
What may follow

Clear next steps.

  • A cavity-drain membrane system where suitable
  • Tanking or barrier work where specified
  • A maintainable sump and pump arrangement
  • Ventilation and finishing recommendations

The recommendation depends on the property and the evidence found during the survey.

Common questions

Basement waterproofing: questions and answers.

Can every cellar become a habitable room?

Not automatically. Head height, structure, fire safety, access, ventilation, drainage and building-control requirements all affect what is possible.

What is a cavity-drain membrane?

It is an internal drained system that manages water entering the structure and directs it to a safe outlet, often through a sump and pump.

Do basement pumps need maintenance?

Yes. Pumps and drainage channels need to remain accessible and be maintained to the system designer’s schedule.
