The membrane and the roof should be tightly bonded together. There is a certain width of overlap between the membranes, so that a complete waterproof layer can be formed. In order to ensure that the junction between the corner of the wall and the roof on three sides is bonded and obedient, it is best to brush the waterproof coating at the same time to achieve double insurance.
The amount of waterproof coating must be up to the specified amount. The amount of painting is generally about 2 kilograms per square meter, pay attention to the uniform thickness, and the minimum thickness should be more than millimeters, so as to have enough strength. Once it enters the rainy season, there will be a lot of families in Qingdao with the problem of house leakage, in the face of this headache, do you feel helpless, the only solution is to use waterproof materials to build leaks.
The success of the leakage construction depends on the quality of the construction. The following issues should be paid attention to during construction.
The construction base surface must be cleaned. Carefully inspect the waterproof layer of the original leaking roof, completely remove the cracked and blistered waterproof layer, and completely remove the dust on the waterproof layer. If you use polyurethane waterproof coatings, you can also use solvents to paint on the old substrate first, which not only removes dust but also increases the bonding fastness.
The construction roof must be dry. If the moisture on the roof does not evaporate, the new waterproof layer will be jacked up, and the waterproofing effect will immediately fail. Therefore, it is not suitable for construction in rainy days, and it is necessary to wait until the sun dries the moisture before construction, otherwise the water will not evaporate.
Drilling: The principle of hole distribution is to first sparse and then dense, in the jack, and use the pressure fan to punch the hole, the hole in the ballast, silt thoroughly cleaned, through the punching can understand the communication relationship between the holes, so as to determine the grouting hole and the ventilation hole; Grouting : Before grouting, a water injection test should be carried out to check whether the hole is unblocked, and then the ultra-early strength self-leveling cement-based grouting material should be compared to 1:
The pulp is slurry with a stirring machine, and the slurry is put into the slurry storage barrel, and the slurry is sent to the working face by the pressure pump to carry out grouting, and the grouting process can be determined according to the coagulation time of the slurry to ensure its stone strength.

Clean up the base layer Blowing and dust removal Key parts treatment Bottom layer painting Multiple times waterproof layer brushing Coil bonding base requirements The surface of the base layer should be compacted and smooth, and when the cement mortar screed layer is used, it must be fully cured, and there shall be no crisp looseness, sanding, and peeling, which should meet the design requirements. The old and new surface layers must be cleaned without debris and dust, so as not to affect the bond strength. The moisture content of the concrete surface should not be greater than 10%, and the base layer should be dry when applying waterproof coatings.
Generally, it can be observed by experience and naked eye, and it can also be covered with a 1m square material cloth, and after 1-3 hours of sunlight (it can also be heated by a hair dryer), see whether there is soda, if there is no soda, it can be regarded as dry before construction.
There are two methods: grouting method and caulking method. First dig a week at the junction of the tunnel and the cement, the U-shaped joint of the cement chiseled and each leakage of the plane leakage are U-shaped, clean the surface of the leakage layer, rinse it clean, that is, use the quick-setting water-stopping material to bury the pipe, pump, and reduce the flow of water, the groove should not be filled at one time, so as to leave room for the caulking, set up a bamboo joint (grouting nozzle) at certain intervals, after the quick-setting material reaches a certain strength, it is possible to inject elastic plugging slurry through the bamboo joint counterpressure, and continue to pour until the deformation joint is no longer water. In case of water, it expands and sets quickly, and then fills the compacted surface layer with castable on the upper part of the concave handle of the deformation joint of the water stop. The combination of material waterproofing and structural waterproofing is adopted, that is, the long-term waterproof and leakage plugging process of rigidity and flexibility.

Waterproof plugging is a combination of waterproofing engineering and concrete engineering. Since both types of projects can achieve the purpose of waterproofing, they are generally referred to as waterproofing projects in the industry. To find the cause of water leakage, we must go deep into the "internal organs" to analyze and judge in order to prescribe the right medicine.
Precautions: The mixing materials are ready to be used as they are used, and the stirred materials must be used up before coagulation; Try to avoid construction under the scorching sun, if the coating is solidified under the scorching sun, sunshade measures and wet maintenance should be added in time, and antifreeze should be added to the construction below 0; When the material is stored, it should be placed in a dry place indoors. After the material is bagged and disassembled, the remaining material should be tied tightly and should not be damp.
In the process of living room decoration, the main spaces that need to be waterproof are bathrooms, kitchens, balconies, etc. The purpose of waterproofing is mainly that when your family uses running water, it will affect the neighbors downstairs through leakage. So when the roof of your own house leaks or seeps, waterproofing your own roof is useless, and you must do waterproofing on the floor of your upstairs neighbor to be effective.
Although users who live on the first floor do not need to do waterproofing, waterproofing can also play a role in moisture insulation and humidity insulation. The general practice of waterproofing is: leveling the original ground with cement mortar, after drying (referring to not wet), brush it evenly with a double combination of polyurethane waterproof coating film for 3 times or use modified asphalt or glass cloth to do two oils and one cloth.
The bathroom wall is required to be high, the kitchen is not lower than the height, and the balcony is subject to the height of the window sill on the outer wall. After drying, the water storage is closed for 24 hours, and the ground construction is carried out after confirming that there is no leakage. If the floor or wall of the original room is damaged, waterproofing and closed water sealing experiments must be carried out.

Hefei double waterproofBring you the toilet waterproof plugging construction process:
1. Determine the cause of water leakage: according to the leakage location and closed water test, it can detect whether it is pipeline leakage or waterproof layer leakage.
2. The solution to pipeline leakage is like a ruler: if the water pipe is leaking, open the floor tile to find the joint of the water pipe below, and then reconnect all the joints after Youhui, after the operation is completed, bury the water pipe in the ground and smooth it with cement mortar, and finally you can re-lay the floor tile to restore the original state.
3. The solution to the high leakage of the waterproof layer slag: the waterproof layer leakage needs to smash all the tools used in the structure above the waterproof layer, and then clean up the grassroots layer, which is the level of the grassroots layer. Use the plugging king material to fill the leakage area, and after the base layer is dry, the polymer polypropylene waterproofing membrane can be laid.

If there is a water leakage problem in the basement, the leakage will generally be filled by grouting and plugging. What is the construction process of waterproof grouting and plugging? What are the matters that need to be paid attention to in the construction of grouting and plugging?
First of all, determine the location of the water leakage, if the gap in the water leakage location is deep, drill a deep hole of 20 to 30 cm; After the hole is drilled, the grouting water-stopping needle is buried and sealed with cement; Then adjust the pressure and slurry volume of the grouting machine, inject the grout into the crack after adjustment, and stop the grouting when the grout does not enter; After the slurry is dried, it is enough to smooth the base surface.
Matters that need to be paid attention to in the construction of grouting and plugging leakage.
1. Before officially starting the grouting process, it is necessary to check whether the grouting machine system can be used normally, and check whether the grouting hail calling valves, pipelines and other parts are tightly installed. Before construction, the valve head must be tightened to avoid the problem of slurry in the later construction process.
2. When grouting is made, we must always pay attention to the changes in the pressure gauge and time of the grouting machine, if you need to inject more grout, you can not grouting at one time, and you must use intermittent grouting methods, so that the grouting effect will be better.
3. If it is basement grouting, if there is leakage or other problems in the grouting process, the grouting construction should be stopped in the first time, and the grouting should be taken after taking closed measures.
4. If during construction, the pressure suddenly rises sharply due to pipeline blockage or other position blockage, but the blockage is washed away and the pressure drops, which is a very normal phenomenon.
5. During construction, we must ensure that the construction site is well ventilated, and we must stay away from any source of goods to avoid bad accidents and disasters.
6. During the construction process of grouting, the construction personnel must take protective measures.
After reading the above, I believe you have a certain understanding of the matters that need to be paid attention to in the construction of grouting and plugging. If you want to know more about it, please continue to ******, and more exciting content will be presented to you in the future.
