At Metro Cash&Carry market, an inspection of the waterproofing was conducted following reports of water leakage into the building. It was found that there were weak spots in the ventilation ducts, which were subsequently siliconized.

Additionally, it was discovered that the covers of 2 “Pluvia” type drains were unlocked, causing water to leak into the building through the installation. Furthermore, sealing was performed on the roof dome at the junction with the fitting collar, where water was also leaking.

Below are photos taken before, during, and after the repairs.
