News Abstract: houses and other buildings for a long time, there will be cracks, water leakage and other problems. However, people do not know much about the professional term of waterproof and plugging, so when looking for someone to construct, they will worry about being "slaughtered". In fact, the reason is very simple. We can understand it after a look.

Housing and other buildings for a long time, there will be cracks, water leakage and other problems. However, people do not know much about the professional term of waterproof and plugging, so when looking for someone to construct, they will worry about being "slaughtered" when looking for someone to construct. In fact, the reason is very simple. You can understand it after a look.
(1) Water characteristics:
Water is pervasive. It gradually penetrates into the interior of the building by means of wind pressure, convection, impact, adhesion, capillary and other forces, and is not easy to detect from the surface in the process of infiltration. In other words, in order to find out the cause of water leakage, we must go deep into the "internal organs" to study and judge, so as to suit the remedy to the case.
(2) Pressure change of water and steam: Once the water seeps into the building, in the limited space, when it is exposed to the sun and generates heat energy, it will form water vapor. The pressure generated by the steam is enough to destroy the original waterproof layer, and even the decoration and decorative materials on the surface (for example, paint falling off, wallpaper blackening, tile bulging, wood floor bulging). The middle change is: 1 mmole of water 18G, volume of 18cc; 1 mol of water vapor, volume 22.4 L = 22400 CC. In other words, if a unit of water is completely turned into steam, there will be a pressure of 1240 times in the limited space inside the building. The destructiveness of this pressure is really terrible. (therefore, we often find that the waterproof glue is applied on the water containing foam cement, and soon the whole swelling and peeling off.)
(3) Waterproofing must be done on a solid body: The interface connected with waterproof materials must be free of swelling, sand, honeycomb, wood, paper scraps, sludge, small stones, and can not be used on the loose and not firm body. The reason is that the poor adhesion, combined with the solar ultraviolet damage, the building itself thermal expansion and contraction, and the water vapor pressure damage, are easy to cause the waterproof layer aging and failure.
(4) Positive waterproofing is better than negative waterproofing: for example, roof waterproofing should be done directly on the roof surface; wall waterproofing should be done directly on the outer wall; water tank leakage should be done directly in the inner layer of water tank; if there is water seepage in bathroom, bathtub and tile should be removed, and waterproof should be done again. Why? Water pressure will spread to other places, and the dead corner of the house is not easy to construct. The term "superior" here is relative, not absolute. With the development of science and technology, there have been some people in the market who have launched waterproof materials for negative construction, such as silicic acid series permeable powder with negative water pressure resistance, and high and low pressure injection of synthetic resin to produce expansion crystals, which can also be waterproof. However, not all occasions can be successfully constructed, so positive waterproof construction must be adopted.
(5) Barrier waterproofing is easy to fail:
Waterproof should be treated from the root, with the method of containment, water is everywhere, will also produce pressure damage, the root can not be long-lasting, for example: the location of the leakage on the top floor, just in the covered illegal building room, ordinary people want to cut off the water from the periphery, which is easy to fail.
(6) The definition of leakage prevention is as follows:
No matter the size of the water pressure, no matter how many days of rain, no matter whether there is water on the roof, no matter whether there is water on the roof, it can not leak. This is called waterproof and leakage stopping
(7) The concept of "no cost of waterproof and plugging": in order to achieve the waterproof effect, it is not necessary to spend money. In addition to "deterioration", concrete itself has waterproof function. For example: the houses built in the Japanese era have no tiles, stone washing and Erding hanging on the external walls, but they will not leak. On the contrary, after the expensive imported waterproof coating is applied to the houses in the villa area, the top-grade Erding hanging still leaks! However, in the Japanese era, the construction of muddy water works was rigorous and careful, and proper treatment was carried out in advance on the parts where water leakage might occur.
(8) No material is omnipotent:
Any kind of waterproof material has its uniqueness and applicability. The concept of "treating all diseases with one dose" is wrong. Therefore, how to choose materials is an important issue. Good doctors are leading the "medication" rather than being led by the "drug" by the nose.
(9) Criteria for the selection of waterproof materials (how to use materials appropriately and appropriately)
1. Connection with the body.
2. Elastic elongation.
3. Water permeability.
4. Compressive strength and tear strength.
5. Weather resistance and aging resistance.
6. Adhesion of surface decoration materials.
Understand these, we will find the company to do waterproof and plugging project, we can understand in mind.
