Multi-Level building with underground car park.

During the rain water is freely coming inside from the newly-build concrete parking walls causing leaks and floods, making the parking wet and moldy and the same-level storerooms impossible to use.

AWC Group completed all the works required to Fix the leaks and Waterproof the area


We’ve detected that the Water Penetration Points were: Cove joint (floor/wall joint), Cold joint shotcrete basement walls and Concrete piles, Porous concrete, Foundation wall crack and Wall /Ceiling joint.

First of all – we’ve removed the efflorescence and calcium deposits, created by the coming from the walls water.

Then, according to the standards, removed the packers and cleaned the walls from the leftovers of Polyurethane Injection Resin with grinder and wire wheel cup brush.
