Try to use glass glue to make a circle around the windowsill.
When there is water leakage on the roof, exterior wall, basement, etc., we should first find out the cause of the water leakage, and then the professional construction team should adopt the corresponding waterproof and leakage repair method to deal with it.
With the passage of time, the uneven growth and decline of buildings, the thermal expansion and contraction due to the change of weather, and other effects, all kinds of micro cracks and cracks will appear on the external wall of the building.
You can also use an external wall waterproof transparent paint to brush around the windowsill for waterproofing.

The reason for the water seepage of the external wall of the waterproof company is that the gap in the window frame is not filled with mortar during the window construction, resulting in the water seepage from the window frame.
With the continuous improvement of building technology and the combination with green buildings, many lightweight wall materials have become the new normal of application.
The construction site must have fire prevention facilities and shall not be constructed at the same time with the solvent coating.
The waterproof coating shall not be applied too thick.
It will cost a lot of money to set up a frame.
Before construction, the line shall be snapped and trial paving shall be carried out to make the coiled material paving position accurate.
The waterproof and plugging method of the basement of the waterproof company must find out the water leakage point and line through chiseling, and carry out targeted plugging; The principle of rigid and flexible combination, expansion and reinforcement combination and external rigid and internal flexible shall be adopted for the plugging of water leakage points and water leakage lines, that is, flexible grouting plugging materials that can be grouted, expanded and penetrated in water must be selected internally, and rigid high-strength plugging agent shall be used for external plugging; The plugging of settlement joints must be carried out in the joints.
If the external wall is pasted with small-size tiles, it is more likely to cause leakage due to insufficient waterproof treatment.
At the joint of concrete beam column and masonry, anti crack net shall be laid as required before plastering, and then plastering shall be carried out as required to prevent cracks in the plastering layer at the joint.
Water and other substances shall not be added to the waterproof slurry.
When the hot melt adhesive on the surface of the felt melts into bright black, the coiled materials shall be rolled with a press roll to discharge the air under the coiled materials and make them stick firmly.
The governance measures for building exterior wall waterproofing of the waterproof company strictly control the construction quality of the exterior wall.
Next, the company will introduce the causes and treatment methods of exterior wall waterproof and leakage repair for everyone to understand.
Pipe orifice, internal corner and other parts shall be plastered into circular arc chamfer.
The general solution is to brush waterproof paint on the exterior wall, but it is very troublesome.
Special attention shall be paid to the door and window openings, scaffold holes, reserved openings, cornices, awnings, balconies, window sleeves, downspouts and other details on the external wall.
Rainwater can enter the wall along these cracks and affect the indoor wall surface, which requires timely water prevention and leakage repair of the external wall.
The root of the external wall of the basement leakage reason of the waterproof company; At the wall parts on both sides of the basement deformation joint; Sewer pipes crossing the outer wall of the basement; The heating pipe of the waterproof and leakage stoppage company passing through the outer wall of the basement; The junction of apron and external wall; Individual wall surfaces with uncompacted masonry.
The strength of bonding and extrusion at the lap seam shall be subject to the extrusion of hot melt adhesive, and the overflowing hot melt adhesive shall be scraped flat with a scraper while it is hot, and the edge shall be sealed tightly.
Many people have some misunderstanding about it.
These parts are weak points for anti leakage.
The basement is a room located underground.
If there is water seepage in the basement, first of all, find out the causes of water seepage in the basement and where it mainly occurs.
The combination of rigid and flexible, expansion and reinforcement and the combination of four plugging lines are very effective, that is, from the inside to the outside, there are four lines of Defense: soft, rigid, flexible and rigid; The leakage inside the line pipe must be plugged when plugging; Only when the leakage stoppage of basement works is carried out from the inside of the project, the scheme is reasonable and the operation is correct, can good results be obtained..
It is easier for water to seep at the windowsill pressing plate, so pay more attention there.
At present, almost all the walls are made of concrete hollow bricks.
The lap width of the coiled material of the waterproof and plugging company shall not be less than 100mm.
Key points for waterproof and leakage repair operation of the waterproof company the basement exterior wall waterproof adopts the “external prevention and external sticking (coating) method”, that is, the facade coiled material shall be paved or the paint shall be painted on the waterproof structure.
Next, we will give you a detailed answer about the water leakage in the basement, find out the reasons for the water leakage in the basement, and select the appropriate waterproof and leakage repair construction methods according to them.
When laying coiled materials, it is required that the base course and the bottom surface of the materials shall be uniformly heated at the same time during baking.
Next, let’s learn about the relevant operation points and precautions of waterproof and leak repair of the waterproof company for everyone to understand.
There shall be no open water in the base course.
The waterproof layer shall be painted evenly.
