<p>Method of detecting and locating leaks in a building which comprises depositing different water-soluble substances or combinations of substances as trace materials in different parts of the building which may be effected by water leaks. The trace materials may for example be deposited on the surfaces of membranes (2), (3), (4) located in cavities (7) under floating floors (9), or in wall cavities (14). A record is kept of the location within the building of each different trace material, so that water from leaks can be analysed for such trace materials and the results compared with the record for the building to trace the path likely to have been taken by the water leak and hence trace the source of the leak.</p> |
