A waterproofing inspection is a detailed assessment of a building or structure to identify existing or potential problems with its waterproofing system. This can involve inspecting membranes, joints, penetrations, balconies, rooftops, basements, wet areas and other locations where waterproofing failure or water entry may occur.
Inspections may be required when there are visible signs of a problem, such as leaks, dampness, water staining, mould or deterioration, but they can also be carried out before remedial works begin, when investigating building defects or to assess the condition of an existing waterproofing system. Following completed repairs, further inspection and testing can also help determine whether the issue has been properly addressed.

Waterproofing inspections are commonly required across commercial buildings, strata and apartment complexes, civil structures and residential properties. They can provide property owners, strata and building managers, facility managers, contractors, consultants and homeowners with a clearer understanding of the condition of the waterproofing and any areas requiring attention.
With more than 43 years of experience in waterproofing and remedial services, Remseal brings extensive practical knowledge to every inspection. Our experience with different waterproofing systems, building types and remedial projects allows us to assess not only visible signs of failure, but also the surrounding areas and factors that may be contributing to the problem.
Remseal provides professional waterproofing inspections and reporting throughout Sydney. Depending on the requirements of the inspection, this may include moisture testing, thermal imaging, photographic documentation, defect reporting and recommendations for remedial works. Our findings provide clear, practical information to help determine what action is required and plan the appropriate next steps.
