Shenzhen exterior wall waterproof company is here to give you a more detailed analysis of this problem.
Due to the limitation of conditions, residents and decorators cannot seriously deal with it; During the construction of shear wall, the bolt casing is not carefully blocked or not blocked before internal and external powder.
Bolt socket holes shall be filled with micro expansion cement mortar.
Special personnel shall be assigned to seal and fill the opening.
The first step to do a good job of waterproof is to do a good job in the waterproof of the balcony ground to ensure that the ground has a slope and the lower side is the drain.
In addition, it should be noted that in the decoration and layout of family balcony, we should not only do a good job in painting waterproof materials, but also remember to make a waterproof slope to facilitate the flow of water to the drain.
Of course, if the foundation waterproof is done in advance, the waterproof effect will be better.
Clean the periphery of the window frame, find the leakage gap and analyze the causes of leakage; If there are holes in the wall, chemical grouting or filling with other elastic waterproof materials can be considered according to the specific situation; Clean the gap surface of the window, and there shall be no oil stain, floating dust and other separators on the surface; In view of the falling off of the sealing material, the elastic sealing material can be embedded in the gap around the window frame; Leakage repair and waterproof treatment of exterior wall.
There are hard ceramic tiles on the surface of the waterproof layer.
For example, the roof waterproof should be done directly on the roof surface, the wall waterproof should be done directly on the outer wall, and the leakage of the water tank should be done directly on the inner layer of the water tank.
When the balcony is waterproof, in order to avoid the inconvenience of lower floor residents caused by water leakage, the thickness of waterproof layer shall be at least 5mm during construction.
The joints between the ground and the wall of the balcony and those 30 cm upward also need to be painted with waterproof paint.
The water will spread to other places under pressure, and it is not easy to construct in the dead corner of the house.
Later, as the masonry is compressed and deformed due to the mortar joint, the wall sinks, and a gap is formed between the inclined brick and the beam and slab.
External wall leakage is mainly caused by poor wall masonry quality, improper treatment of external wall openings, unqualified quality of external wall plastering or pasting face bricks, etc; The water leakage of the bay window is mainly due to the weak connection between the aluminum alloy or plastic steel window frame and the wall and the lax sealing.
According to the traditional method, pry open the outer ceramic tiles, dig out the waterproof layer, make a new waterproof layer, and then lay ceramic tiles again.
The exterior wall opening is not handled properly, and the connection with the original opening is not strict when the feeding opening is blocked and masonry; After the completion of the project, residents chisel air conditioning pipe holes, solar water heater pipe holes and exhaust fan holes on the wall, resulting in cracks in the wall and external powder.
Cause analysis and treatment measures of external wall water leakage poor wall masonry quality among various common quality problems of brick masonry, the reasons affecting external wall leakage are as follows: the mortar fullness of horizontal mortar joint of brick layer is less than 80%, there is no mortar (empty joint or blind joint) in vertical mortar joint, and an internal channel is reserved for rainwater leakage; When the infilled wall in the frame structure is built close to the beam bottom or slab bottom, the inclined brick is built from the top to the beam and slab bottom without stopping.
The “superior” mentioned here is relatively comparative, not absolute.
Among them, labor cost, material cost and time consumption are very large.
Generally, it is enough to paint waterproof coating 2 to 3 times.
Grouting hole design and hole layout design the hole layout of grouting hole has two forms: cross joint and inclined hole, which can be selected according to the actual situation and needs, and can be used at the same time when necessary.
During masonry, the bent reinforcement is pressed into the brick layer to form a large gap between the masonry and the column at local positions, which is prone to cracks during plastering.
Determine the waterproof and plugging scheme according to the waterproof and plugging construction process, conduct on-site inspection before plugging, find out the construction situation, analyze the leakage causes, find out the location, crack, crack or perforation width, length, depth and penetration of the leakage, understand the leakage in rainy and sunny days, measure the flow and flow rate of the leakage, and make all preparations by fully and correctly formulating the plugging scheme.
Many family balconies begin to seep water from the outside to the inside in the rainy season, which is caused by the failure to do a good job in waterproof work during decoration.
If the building leaks water, it means that it is the problem of waterproof layer treatment.
When the outer wall is plastered or scratched, a crack is formed at this gap; The tie bar between the frame column and the infilled wall does not meet the modulus of the brick.
