Some exterior walls with veneered tiles create water seepage after heavy rain. After on-site observation, the characteristics of the water seepage part are: the outer wall brick hollow drum and the brick joint crack. Rainwater enters the room from the outside. There are some channels for the factory:
First, the gray seam of the brickwork
1. With dry brick wall, the mortar is dehydrated early, and the dust on the brick surface acts as a barrier to weaken the bond between the brick and the sand, forming a gap.
2. In the brick masonry, the ash is too much at one time, the masonry speed cannot keep up, and most of the moisture in the mortar is absorbed by the bottom brick, so that the bricks that have just been built are lost to the mortar.
3. The mortar of the vertical wall of the brick wall is not full, even without mortar, forming a translucent "glass wall" phenomenon.
4. The vertical joint mortar between the two bricks is not full and forms a groove.
These places provide convenient conditions for the storage and penetration of rainwater into the room.
Second, the fixed template tube card hole
1. When the ring beam is supported, the horizontal struts buried in the wall are not removed after pouring the concrete, and then they are cut and dried in the wall.
2. Fixed structure: The outer template is about the tube hole, the scaffold hole, etc., and then carefully fill according to the requirements of the operation rules, and cover it when dry or plastering.
Third, the bottom layer of plaster and tile inlays, cracks
1. The base plaster is too thick at one time, and the dry shrinkage rate is large, resulting in empty drums and cracks.
2. The consistency and water retention performance of the mortar does not meet the actual requirements of the site. Difficulties in operation, the base mortar is not dense, and cracks appear?
3. The watering of the wall is insufficient. After the plastering, the water in the sand pad is mostly absorbed by the base layer. The bond is weakened and an empty drum is produced.
4. The tile is not soaked in water or soaked and not dried, so that the adhesion is reduced or empty.
5, the surface-transparent brick-bonded mortar does not meet the requirements, the worker operates as a simple cement paste bond, which is easy to cause the hollow or crack of the tile.
6. The surface brick joints are not constructed in accordance with the requirements of the operating procedures, resulting in cracks.
The combination of these three conditions led to the infiltration of rainwater into the room from the wall. Such as
During the construction, these channels are eliminated and the water seepage phenomenon is eliminated. To this end, in the construction, construction should be strictly in accordance with the requirements of construction specifications and operating procedures, and each process should be done carefully to prevent the occurrence of quality problems.
