Commercial Waterproofing Leak Investigation
When water ingress affects a commercial building, the visible leak is often only part of the problem. Moisture can travel through construction, track across interfaces, and appear far from the original point of failure. Without proper investigation, remedial works can be misdirected, repeated, or unnecessarily disruptive.
At Advanced Damp, we carry out commercial waterproofing leak investigations to help identify likely ingress routes, assess waterproofing failures, and guide the next stage of remedial action. This service is suited to contractors, developers, surveyors, property managers, and commercial building owners dealing with recurring leaks, failed previous repairs, or unclear waterproofing defects.

When a commercial waterproofing leak investigation is needed
A commercial waterproofing leak investigation is usually needed when water is entering a building and the source is unclear, disputed, or more complex than a straightforward repair issue.
This often applies where:
- Leaks continue after previous repair works
- Water is affecting basements or below ground areas
- Ingress is appearing around terraces, roofs, or podium decks
- Internal staining is visible but the entry point is uncertain
- Several possible causes exist and the route of ingress is not obvious
- There is a need to assess waterproofing failure before remedial works are specified
- The building contains critical areas where recurring leaks cannot be left unresolved
In many commercial buildings, the challenge is not only stopping water ingress. It is understanding how water is moving through the structure and where the failure is most likely to be occurring.
What we investigate
We investigate commercial waterproofing issues across a range of building elements and structural situations.
Basements and below ground structures
Below ground spaces present some of the most persistent waterproofing problems in commercial buildings. We investigate water ingress affecting basements, retaining walls, lower ground areas, service voids, plant rooms, and other below ground structures where waterproofing performance is critical.
Podiums, terraces and flat roofs
Podiums, roof decks, and terraces can produce difficult leak patterns because water may travel before becoming visible internally. Investigating these areas properly helps reduce guesswork before opening up or repair works begin.
Walls, joints, penetrations and interfaces
Waterproofing defects often arise at changes in construction, movement joints, service penetrations, slab to wall junctions, façade interfaces, and other vulnerable details where moisture can bypass the intended protection.
Plant rooms, service areas and critical spaces
Where water ingress affects plant rooms, managed service areas, storage spaces, circulation routes, or operational parts of a building, early diagnosis is important to reduce disruption and limit the risk of repeated failure.
Our commercial investigation process
Our approach is structured around identifying the likely source of ingress as clearly as possible before waterproofing repairs are specified.
Initial review and site assessment
We begin by reviewing the reported issue, visible symptoms, known history of the defect, affected areas, and the relevant building elements. This helps build an early picture of where the waterproofing problem may be developing.
Moisture tracing and targeted inspection
We assess the areas affected and use appropriate investigation methods to understand likely routes of water ingress. Depending on the issue, this may involve visual assessment, moisture mapping, targeted inspection, and consideration of how water may be travelling through the structure.
Findings and remedial recommendations
Once the issue has been assessed, we provide clear findings on the likely source, vulnerable locations, and the most appropriate next step. This may involve targeted waterproofing repairs, opening up works, further technical review, or a more defined remedial strategy.
Our aim is to provide direction that is practical, proportionate, and relevant to the building.
