Xypex Concentrate and Patch'n Plug were used to repair and protect the three-story underground parking garage at Jaidah Square in Doha, Qatar. The building’s original traditional membrane had failed due to a high ground water table and extreme hydrostatic pressure. Xypex was successfully used to stop the leaks and the developer was very happy with Xypex’s ability to perform in critical situations. The 70,000 m² commercial building completed on time and in 2011 Jaidah Square won Commercial Project of the Year in Qatar.
