Repairing of underground garage roof waterproofing

The study was commissioned by NCC Real Estate to find out the reasons of underground garage roof waterproofing damages to prevent the repeat of leakages. What is more, the purpose of the thesis was to develop principal works for repairing and determine what should be improved in the design project. For that purpose, basic garages structures and types of operational roofs were learned depending on their implementation, loads and structures. Besides garages were considered as an urban infrastructure object. Data for this study was collected during the practical training at NCC Real Estate, Saint-Petersburg at Swedish Krona construction site. The information was gathered from the design project, subcontractors’ reports, co-workers’ experience, literature, the Internet, manufacturers’ guides and local and international norms. The final result of this thesis was the recommendations to the design project and construction works organisation that have the main influence. The weakest sides of construction that could lead to the leakages were determined. The findings have been implemented to the final parking phase construction, so the results show positive development
