The underground waterproof requirements are strict, and the side wall of garage floor.
Coating protection is very important.
The “eight phrases” of waterproof construction must be kept in mind that waterproof is simple, because the materials are “convenient”, and many non professional teams fishing in troubled waters can also achieve short-term waterproof without leakage.
Additional treatment of expansion joints at internal and external wall corners shall be emphasized.

03 water vapor must not be left.
The key is to solve the problem of water string, and the coiled material construction should be fully adhered.
The quality of products should be reliable, with excellent technology and raw materials.
The film shall be painted twice and three times, and the vertical painting shall be completed.
Because if the large-scale construction is carried out first, the node treatment may not be comprehensive and detailed enough.
There are key points in roof waterproof roof construction, and the node treatment shall be carried out in advance.
05 node painting can not be omitted.
02 dust particles have a deep impact, and quality problems are born in this life.
Do not have moisture.
If there is dust and the coating cannot be fully bonded with the solid base, the waterproof coating will fall off.
First brush a coating layer and strengthen the mesh cloth in it.
As the owner, he may not be proficient in the process, but he can know the key points clearly.
Due to seasonal climate problems, it cannot be considered that the closed water test can be carried out two or three days after coating.
Remember, they are very good for waterproof construction! 01 indoor waterproofing is the first pass.
Design considerations should be comprehensive, and wear raincoats to ensure safety.
The treatment of pile head shall be fine, and the expansion rubber strip shall be bound.
Once the moisture content of the base course is too high, the waterproof coating will be washed and bulged by water vapor pressure, resulting in bubbles and affecting the waterproof effect.
The bonding of side wall depends on the site.
There is no money for rework.
Lap joints shall be staggered, and asphalt shall be baked during construction.
Large surface construction is in the back, and small nodes are given priority.
The base course is firm and does not drop bricks.
Once there is a problem, it is very troublesome.
For example, for internal corners, waterproof material can be brushed once in advance, and then reinforced mesh cloth can be laid.
The existence of water vapor in the base course poses a great threat to the organic waterproof layer.
After the waterproof construction, we must pay attention to the later protection work.
In particular, the organic waterproof coating itself has a large surface tension during construction, which is not easy to infiltrate and spread.
Mesh reinforcement must be related to node treatment.
If the strength of the base course is low, the bonding between the waterproof layer and the structural base course will be weak.
04 don’t worry about the construction of large surface.
When waterproof brushing is carried out, three times of construction shall be adopted, and the next construction shall be carried out after each side is dry.
It is recommended to construct three times and dry the next layer.
Because the organic waterproof coating is not only impermeable, but also impermeable.
Only a professional team can give full play to the durability effect of waterproofing, rather than a temporary “blindfold”.
Underground, kitchen and bathroom and roof waterproof works are very important.
We respect originality,.
08 don’t worry about comprehensive drying.
For example, the most indoor waterproofing is the treatment of toilet and bathroom.
Under the external force of the subsequent protective layer and finishing layer, it will cause hollowing and falling off, resulting in a series of leakage disputes.
Considering that if the drying is not satisfied, the film will have no strength, which is likely to cause serious damage to the film during other operations, and the water vapor in the non dried film will also cause harm to the waterproof layer.
Kitchen, bathroom and indoor waterproof shall be safe, and the base course shall be solid without falling bricks.
Therefore, when checking the firmness, you can feel the surface of the base course with your hands and observe whether there is cement gravel falling off.
The waterproof shall be protected after completion, and the subsequent damage shall be as fierce as a tiger.
07 the protection work must be in place, leaving no chance for rework.
Start from the strengthening of nodes.
The bottom plate should be laid empty, and the settlement and damage allowance is sufficient.
All dry for two days, closed water experiment is safer.
It’s not complete until the water is closed.
Why should we be so careful? Because the existence of dust will play an isolation role between the base course and the waterproof layer.
The following is the site teachers’ summary of the key points of various waterproof construction in the form of doggerel in combination with the experience and lessons of waterproof engineering.
Therefore, you can’t fool around in waterproofing.
The time of closed water test must be well controlled.
Whether it is an organic film or an aqueous film, the strength of the film has a process of strength growth.
For example, the construction of protective layer and the installation of building accessories should be reasonably arranged to minimize the impact on the waterproof layer.
The external bonding is different from the internal bonding.
If there is a problem, it should be leveled and repaired in time.
It’s best to wait until the application and drying are completed.
Careless construction is worth doing.
06 three times of brushing depends on the technology, and the coating is effective.
Therefore, priority should be given to the overall waterproof.
Here are eight proverbs.
It has always been said that waterproof treatment can be carried out only after the base course is kept clean.
Pay attention to the paving of large surface, and there are requirements for horizontal and vertical joints.
These are two concepts.
In the waterproof construction, first deal with the internal and external corners, pipe roots, floor drains and other node parts, and then carry out the waterproof construction of large surface.
Then apply the secondary coating to ensure that the reinforcing layer is perfectly in the middle of the coating, which can effectively protect the waterproof layer from being damaged by stress or other factors.
Here we want to talk about another important issue, which is the moisture content of the base course.
Dust also has a great impact, delaying construction and poor quality.
It is difficult to say that waterproofing is difficult because the materials have authenticity and adaptability.
Don’t let bubbles fill the wall.
The reasons involve design, materials and construction.
Accurate measurement is the premise and the overall control system is complete.
You are in a hurry to bubble.
Those who can stop leakage don’t mean they can do maintenance.
It’s really talented to spread knowledge in this way! Overall design, small leakage problems in buildings, product quality plus design.
The product quality is very good.
The node is the weak part of waterproof, which is the top priority.
