The difference between roof damage and roof capping.

The difference between roof water cut-off and capping is that roof water cut-off is the follow-up work after capping: roof water cut-off refers to the need to cut off roof water and construction water in order to prevent pollution to decoration when the main structure roof is completed and the secondary structure construction is completed. The concrete measures are roof waterproofing, roof hole plugging, external wall water cut-off and temporary or permanent plugging of holes between floors to prevent the roof from being produced after decoration. The capping means that the main project of the top floor of the building has been completed. Generally, pouring concrete (or covering the floor) is called capping, and building capping is not complete. Capping generally refers to structural capping, and there are still many things to be done after capping, such as external walls, internal pipelines, water and electricity, etc. Mainly the construction and construction of internal and external decoration, water and electricity ventilation and other supporting facilities.
