Many of the underground parking garages in Belgium have leaks. It is common to see water infiltration from the moment that the parking garage is commissioned. The extent of leaks varies (from slight to extremely serious infiltrations). However, detecting and repairing a leak is not so easy. One of the problems is that paving, terraces or parking roof decks are usually installed on the roof of parking garages.
Since it can take a long time to detect leaks in a parking garage, the costs can also escalate. And this is certainly not an incentive for good relations between the client, contractor, renter or purchaser. Very often, detecting a leak can escalate into legal proceedings, with the actual problem not being solved.
