What is flexible waterproofing, what is rigid waterproofing Flexible waterproofing

: Flexible waterproofing material refers to a waterproof material with flexibility. In addition to its excellent waterproof and impermeable properties with other waterproof materials, the flexible waterproof material has high tensile strength, high elongation, bending resistance and other properties, which can adapt to the natural deformation of the building, and the waterproof layer is not easy to crack.

Among the flexible waterproof coating products I have used, I recommend the brand Dunlop to you, the waterproof and moisture-proof function of this product is very professional, and there is a full set of waterproof products. The decoration of my new house is also a Dunlop waterproof product, and there is no leakage on typhoon days. However, if you are on waterproof products, it is still recommended that you find a master, and you still don't have a master to do a good job.

Dunlop, a well-known brand of the German ARDEX GmbH Group, as a leading manufacturer of building materials from Europe, is here for you....

Flexible waterproofing is relatively rigid waterproofing, and flexible waterproofing is mostly membrane waterproofing. Rigid waterproofing mainly relies on adding waterproofing agent to concrete, or improving the gradation ratio of concrete, increasing its impermeability, which is more suitable for basement waterproofing. As for the roof, it depends on what type of roof, the service life of the building and the design level are determined, there are flexible, rigid, and coated films, and not all of them are suitable for rigid waterproofing.

Areas of use.

The flexible waterproof material has high tensile strength, high elongation, light weight, and convenient construction, but the operation technical requirements are strict.

1. Rigid waterproofing refers to: when the waterproof layer is subjected to a tensile force greater than the tensile strength of the waterproof material (including settlement deformation, temperature difference deformation, etc.), the waterproof layer is brittle and cracks and causes water leakage, which is called rigid waterproofing.

2. Flexible waterproofing refers to the fact that when the waterproof layer is subjected to external force, the waterproof material itself has a certain elasticity and ductility (elasticity like rubber), which can resist the cracking of the base layer within the elastic range of the waterproof material, showing a certain flexibility. Such as rubber membrane waterproofing, polyurethane coating waterproofing.

Features: The material used for rigid waterproofing is not elastic. For example, common rigid waterproof materials include fine stone concrete, waterproof mortar and cement-based permeable crystalline waterproof coatings.

Compared with flexible waterproof roofing, the main advantages of rigid waterproof roof are low cost, good durability, less construction process and convenient maintenance.

Rigid waterproof difference:

Rigid waterproofing is easy to crack and seep due to temperature difference and strain; Flexible waterproof, mostly asphalt, linoleum and other organic materials, easy to age, short life.

Rigid waterproof material refers to cement, sand and gravel as raw materials, or a small amount of admixtures, polymers and other materials, by adjusting the mix ratio, inhibiting or reducing porosity, changing pore characteristics, increasing the compactness between the interfaces of raw materials, etc., to prepare cement mortar concrete waterproof materials with certain anti-permeability ability.

Flexible waterproof material, also known as linoleum membrane waterproof layer, is made of linoleum, glass cloth and other fiber fabrics as the membrane of the tire layer, with various cementing materials such as asphalt, etc., the membrane is bonded to the screed layer on the roof structural plate and formed by the waterproof layer. The flexible waterproof material has high tensile strength, large elongation, light weight, and convenient construction, but the operation technical requirements are stricter, and the puncture resistance and aging resistance are not as good as those of rigid materials.

Rigid waterproofing.

Rigid waterproof village materials are made of cement, sand and gravel as raw materials, or mixed with a small amount of admixtures, polymers and other materials, by adjusting the mix ratio or reducing porosity, changing the pore characteristics, increasing the compactness between the raw materials, etc., the cement mortar concrete with a certain anti-permeability ability is formulated into cement mortar concrete, which is summarized in the vernacular This waterproof material is made of mortar or concrete. It is characterized by brittle cracking of the waterproof layer when the tensile force of the waterproof layer is greater than the tensile strength of the waterproof material (including settlement deformation, temperature difference deformation, etc.), resulting in water leakage.

Advantages: long service life, simple construction technology, easy to take materials, convenient maintenance.

Disadvantages: Because the weight of the room itself is too large, the structure of the room is also relatively limited, and with the change of temperature difference, it is easy to crack and seep.

Flexible waterproofing. Flexible waterproof materials are mostly asphalt, linoleum and other organic materials, also known as the waterproof layer of the felt membrane by professionals, which is a membrane made of felt, glass cloth and other fiber fabrics as the tire layer, and the membrane is bonded to the screed layer on the roof structural plate with various cementing materials such as asphalt. It is characterized by the fact that when the waterproof layer is subjected to external force, it has a certain elasticity and ductility, which can resist the cracking of the base layer within the elastic range of the waterproof material, showing a certain flexibility.

Advantages: high tensile strength, large elongation, light weight, convenient construction, can adapt to certain deformation and expansion and contraction, and is not easy to crack.

Disadvantages: The operation technology requirements are high, and the aging resistance is not as good as the rigid waterproof material, so it is easy to age and has a short life.

What is Rigid Waterproofing and What is Flexible Waterproofing? Don't buy waterproof materials indiscriminately.

Rigid waterproofing is characterized by high compressive strength, tensile strength and a certain resistance to permeation. Some multi-functional materials that can be used for both waterproof and load-bearing maintenance. In addition, the flexible waterproof coating is mainly coiled linoleum, and it has good flexibility and strong corrosion resistance, so this is the difference between the two.

1. Rigid waterproof layer: the waterproof layer composed of high strength and non-extension ability, such as waterproof mortar and waterproof concrete.

2. Flexible waterproof layer: a waterproof layer composed of waterproof materials with certain flexibility and large extensibility, waterproof membranes and organic waterproof coatings.

Rigid waterproofing is mostly used in concrete waterproofing, LM waterproofing mortar, etc., mainly the prepared polymer cement mortar is pressed or sprayed on the surface of the waterproof base to form a waterproof layer to achieve the purpose of waterproofing.

Flexible waterproofing is to isolate water through waterproof materials such as membranes and coatings, and LM composite waterproof coatings are flexible waterproof materials, which have low requirements for the base layer and are not easy to crack is a major feature of flexible waterproof materials.

1 First of all, because the waterproof industry is currently in its infancy, products, enterprises, and regulations are very confusing, resulting in very confusing names, and various names emerge in endlessly.

2 Rigid waterproofing and flexible waterproofing are actually corresponding to general-purpose and flexible types. The flexible waterproofing slurry is more flexible, and the general-purpose waterproofing slurry is more prominent.

Flexible waterproof materials, mostly asphalt, linoleum and other organic materials, also known as linoleum membrane waterproof layer, it is made of linoleum, glass cloth and other fiber fabrics.

The membrane of the tire layer is destroyed by using various cementing materials such as asphalt, etc., and the membrane is bonded to the screed layer on the roof structural plate to form a waterproof.

Layer of the spine. The flexible waterproof material has high tensile strength, high elongation, light weight, and convenient construction, but the operation technology requirements are strict, and the puncture resistance and resistance are resistant.

The aging performance is not as good as that of rigid materials, which is easy to age and has a short life.

Waterproofing materials are divided into two types: rigid and flexible

Flexible waterproof materials, mostly asphalt, linoleum and other organic materials, also known as linoleum membrane waterproof layer, it is made of linoleum, glass cloth and other fiber fabrics.

Make the membrane of the tire layer, use various cementing materials such as asphalt, etc., and bond the membrane to the screed layer on the roof structural plate to form a waterproof.

Layer. The flexible waterproof material has high tensile strength, high elongation, light weight, and convenient construction, but the operation technology requirements are strict, and the puncture resistance and resistance are resistant.

The aging performance is not as good as that of rigid materials, which is easy to age and has a short life.

Rigid waterproof material refers to cement, sand and gravel as raw materials, or a small amount of admixtures, polymers and other materials mixed with.

The whole mix ratio, inhibiting or reducing the porosity, changing the pore characteristics, and increasing the compactness between the interfaces of the raw materials.

Cement mortar concrete waterproof material with certain permeability resistance. Rigid waterproofing is easy to crack and seep due to temperature difference and strain;

In the decoration of the house, waterproofing engineering is a key point, whether it is the exterior wall, the ground, the bathroom, or the balcony, it is necessary to do waterproofing treatment during construction. If the waterproofing project is not done well, it is easy to leak in the future use, which will also shorten the service life of the house. Flexible waterproof materials are very commonly used, so what are the flexible waterproof materials?

What are the simple difficulties of flexible waterproof materials.

Common materials such as asphalt, linoleum, two-component waterproof coatings, membrane waterproofing, etc., have high strength, strong moisture resistance, good ductility, and are easy to construct, and are very suitable for roofs, toilets and other places, and are also suitable for wall corners, yin and yang corners and other parts.

What to pay attention to in the construction of flexible waterproof materials.

1. Stir thoroughly.

When using this material, they should be poured into a clean and dry container, and then an appropriate amount of powder should be added according to the proportion, and stirred while mixing, until the waterproof slurry is fully stirred, and there are no obvious particles and no dough, it can be used. For the prepared waterproof slurry, it should be used as soon as possible so as not to affect its performance.

2. Deal with special parts.

For some special pure parts such as pipe roots, floor drain peripherals, yin and yang angles, etc., before painting waterproof slurry, these parts should be plugged with leakage materials to avoid leakage problems in the future. These areas are prone to water leakage, so it is recommended to apply the waterproof slurry several times.

3. Curing and solidifying.

When the waterproof slurry is coated, it should be covered with a damp cloth on its surface, or sprayed with some water for curing, and so on for about 3 days, and the closed water test should be carried out, and it can be used normally after passing the acceptance.
