Why diagnosis matters

Visible damp or mould does not automatically tell you the underlying cause. Moisture can enter from the ground, through external defects, from leaks, or build up internally through condensation.

Our approach is to inspect the clues, explain what is most likely happening and scope the remedial work accordingly.

Common questions

Basement & Cellar Waterproofing FAQs

Clear answers to the questions we are most often asked before a survey or remedial project.

Still unsure? Book a free survey

01 What is the difference between tanking and a cavity drain membrane?

Tanking aims to resist moisture passing through the structure, while a cavity drain membrane creates a controlled space that manages water behind the finished surface. The right approach depends on the construction, water pressure, drainage and intended use of the space.

02 Can a damp cellar be made into a usable room?

Often, yes, but the feasibility depends on the building, floor levels, drainage, ventilation and the amount of water pressure involved. A survey is needed before deciding on a waterproofing system and any associated building work.

03 Does basement waterproofing include the floor as well as the walls?

It can. Successful below-ground waterproofing often depends on treating the wall-floor junction and considering the floor construction as part of the same system rather than looking at the walls in isolation.

04 What happens if water is still entering from outside?

The external source should be considered wherever practical, but below-ground waterproofing systems are often designed to resist or manage moisture that cannot be completely eliminated externally. The specification depends on the site conditions.
