There are so many kinds of waterproof products, how to distinguish?

Some people have houses, houses have to be decorated, there must be waterproof decoration, will use different kinds of waterproof materials, so what are the classification of waterproof materials?
There are two main types of waterproof materials: rigid waterproof materials, flexible waterproof materials.
Rigid waterproof material: mainly refers to mortar waterproof agent, although there are some characteristics of rigid waterproof, but the thickness is very thin, can not achieve enough waterproof thickness and strength, and rigid material quality is heavier, the construction time is a little time. Rigid material is stretched by external force can not be very good tensile, which will make rigid waterproof material brittle cracking resulting in water leakage.
Flexible waterproof material: mainly organic materials are divided into flexible coil and water-based coating, flexible waterproof tensile strength is relatively high, can adapt to a certain deformation and expansion and contraction, not easy to crack, elongation is relatively light, construction is more convenient, easy to use. Flexible material toughness is better, there will be no cracking caused by water leakage.
Different components: waterproof slurry for rigid waterproof, such as fine stone concrete, waterproof mortar and cement based penetration crystallization waterproof slurry, rigid waterproof material is not elastic, but has good anti-aging performance; The waterproof slurry used for flexible waterproof is generally polyurethane waterproof slurry, polymer cement based waterproof slurry and acrylic waterproof slurry, etc., flexible waterproof material has high tensile strength, large elongation, light weight, convenient construction and so on.
Different application scenarios: in home decoration waterproof, if it is wall waterproof, should use rigid waterproof, because it helps late bricklaying, long-term use of the back wall brick will not fall off; The ground should choose flexible waterproof, because flexible waterproof is more resistant to corrosion and flooding than rigid waterproof.
Different materials: Rigid waterproof material is based on cement, sand and stone as raw material mixing ratio, increase the density between the interface of raw materials, etc. Flexible waterproof material, also known as the waterproof layer of linoleum roll, is made of linoleum, glass cloth, etc., with all kinds of cementing material period asphalt, etc.; Rigid waterproof advantages: concrete waterproof material in the general environment has a long durability, seldom carbonization and aging; In the underground engineering of non-corrosive static water quality, almost will not be damaged. Rigid coating has good compression and impact resistance, and the probability of being damaged by external force is small. Bathroom walls are usually made of cement mortar or tile. If flexible waterproofing is used, it may lead to empty drums and fall off, but rigid waterproofing has relatively excellent bonding properties. In case of leakage, the water inlet point can be found for easy maintenance.
Disadvantages: uneven foundation settlement will cause slight deformation of roof components, sensitive to temperature deformation, easy to produce cracks and leakage.
