Water leakage occurs indoors, stains occur slightly, and water dripping occurs seriously. The main reasons are that the construction of building roofs, floors with water rooms, basement bottom plates or outer wall waterproof layers is not fine, the lap joint length is not enough or the sticking is not firm, and the waterproof layers have water leakage points.

Because the insulating layer is usually arranged below the waterproof layer of the building roof, the filling material is usually arranged below the waterproof layer of the water room, and the filling material or the insulating layer is generally made of porous materials and has strong water permeability, when water enters the filling material or the insulating layer through the water leakage point of the waterproof layer, the water can seep to the bottom surface of the insulating layer or the filling material and the top surface of the reinforced concrete floor slab and horizontally flow to finally gather to the slab top position with relatively low elevation. Over time, water can seep from the location through the slab into the room, forming stains. The key point of the problem is that the positions of stains seen in a room are often inconsistent with the positions of water leakage points of a waterproof layer, so that maintenance personnel cannot find out the real water leakage points accurately.

In practical engineering, when leakage occurs on a roof, two methods are available. Firstly, the waterproof and heat-preservation integral of the building roof is removed, and the building roof is constructed again.
