Where can structural self waterproofing materials be used?

Structural self-waterproofing materials can be used in basements, underground parking lots, pools, water towers, underground transfer stations, bridge piers, docks, dams, etc.

The self-waterproof structure of waterproof concrete is to adjust the concrete mix ratio or add admixtures and other methods to improve the compactness and impermeability of the concrete itself, so that it has both load-bearing, enclosure and impermeability capabilities, and can also meet certain freeze-thaw resistance and erosion resistance. The self-waterproofing technology of the Kolo structure was used during World War II in the United States to prevent water and moisture from underground military bunkers. Structural self-waterproofing, also known as waterproof concrete, generally refers to concrete with impermeability grade greater than or equal to P6 level, which is mainly divided into three categories: ordinary waterproof concrete, expansion agent waterproof concrete and admixture waterproof concrete.

It is mainly suitable for industrial and civil construction underground engineering, water intake structures and projects with alternating dry and wet interaction or freeze-thaw effect. Waterproof concrete can be divided into three categories: ordinary waterproof concrete, admixture waterproof concrete and compensating shrinkage waterproof concrete. Structural waterproofing refers to the waterproofing of the reinforced concrete structure, which is mainly cement concrete, also known as waterproof concrete, and generally refers to concrete with impermeability grade greater than or equal to P6 level.

Admixture waterproof concrete refers to the addition of trace organic matter (air-entraining agent, superplasticizer, triethanolamine, etc.) or inorganic salts (such as inorganic aluminum salts, etc.) to the concrete mixture, in order to improve the workability of concrete, improve the freeze-thaw resistance, compactness and impermeability of concrete, suitable for pumping concrete and thin-walled waterproof structure, mixed with QHBQ nano waterproof liquid (comprehensive external additives) of the structure of self-waterproof concrete belongs to multi-functional high-performance composite, self-compacting and self-waterproof concrete.

Rest assured, it will be used in some special locations such as the kitchen and bathroom to rain and waterproof, and some leaks have caused some losses to patients.

1.The classification of waterproof materials includes: synthetic polymer waterproofing membrane; waterproof coatings; JS polymer cementitious waterproof coatings; polymer modified asphalt surface coil; sealing materials; water repellent agent; waterproofing mortar; The grouting material is waterproof; Bentonite waterproofing material.

2.Kitchens, bathrooms, and balconies should be waterproofed. Waterproof sealing coatings are suitable for indoor floors, toilets, kitchens, bathrooms, gardens, flower beds, and hot spring water.

3.The envelope of the building should prevent the infiltration of rainwater, snow water and groundwater; It is necessary to prevent the erosion of moisture, vapor and other harmful gases and liquids in the air; The separating structure should prevent the seepage of water supply and drainage. These materials that are resistant to penetration, leakage, and erosion are collectively referred to as waterproofing materials.

Bridges, warehouses, basements, sewage pools and other places can use structural self-waterproofing materials, but be sure to choose products from regular manufacturers, I know that Koloe is very good, you can go and find out.

The building structure is self-waterproof, which means that the building structure itself can achieve the purpose of waterproofing, that is, the reinforced concrete structure of the building can be both load-bearing and waterproof. Disengagement.

The principle of structural self-waterproofing is to add a certain amount of high-performance expansion agent and waterproofing agent to the concrete to compensate for the shrinkage of the concrete, improve the shrinkage stress of the concrete, and prevent the cracking and leakage of the concrete, so as to achieve the purpose of structural self-waterproofing. Compared with traditional waterproofing membranes or waterproof coatings, structural self-waterproofing has good durability and wide applicability, and the advantages are very obvious. Traditional waterproofing membranes and coatings have a short service life, and often need to be repaired or re-laid after a few years of use, while the structural self-waterproofing is more durable and has the same service life as the building.

The structure self-waterproofing has a good waterproof effect, the adaptability is also strong, and the use is not limited by any construction conditions, and the construction technology is simple, easy to operate, and the construction quality is easy to be guaranteed. Structural self-waterproofing can effectively reduce the construction period of the project, save the project cost input, and the construction process has little impact on the surrounding environment.

The self-waterproofing technology of building structure has the advantages of durability, simple construction technology, low construction cost, small construction impact, and good waterproof effect, and is widely used in many fields such as underground waterproof engineering and civil air defense engineering. In order to ensure the waterproof effect of the self-waterproofing of the structure, the construction personnel should strengthen the quality awareness, construct according to the construction plan and design requirements, strengthen the management of the construction site, and strictly control the construction quality of key parts and key processes in the construction process.

Concrete self-waterproofing refers to the ability of concrete to withstand water penetration, which is a measure of impermeability, which is related to the compactness of concrete.

Kelo is an internationally renowned structural self-waterproofing brand, using concrete doped with Kolo inorganic nano anti-cracking and impermeable agent + external spray Kolo permanent condensate DPS waterproofing agent technology, instead of membrane inorganic non-aging, crack self-repair, to solve the problem of cracking and non-compacting. The construction is simple and reliable, saving time, money and worry.

Current status of leakage in construction projects.

Kolo is waterproof. Kolo is waterproof.

1. 65% of the real estate quality complaints are due to housing leakage

The waterproofing works of the building should be renovated and redone after 6-8 years.

In 2013, the results of a joint survey by China Building Waterproof Association and Beijing Zero Market Research Company. Roof leakage rate:; Underground leakage rate:

2,849 roof samples and 2,716 leaks; 1,777 were sampled underground and 1,022 were leaked.

Cause of leakage. The root cause of concrete leakage is cracked and undense concrete (capillaries, honeycombs, holes, hemp surface problems). Waterproofing membranes and coatings do not improve the cracking and compactness of concrete, but only cover them temporarily.

The lap edge of the membrane is destined to fail, and the organic membrane and coating will inevitably age over time, so the waterproofing of the membrane coating film cannot fundamentally solve the problem. First of all, the general grouting materials are organic materials, and the organic materials have shrinkage and aging problems, and secondly, the adjacent concrete is destroyed at the same time of grouting to make the concrete more loose and easier to leak, which is why many grouting is more leaking.

Solution. Kolo structure self-waterproofing technology system (internal doping + external spraying) is concrete doped with Kolo anti-cracking and anti-seepage agent, and external spray of Kolo permanent condensate DPS waterproofing agent. Originated in the United States in 1899, it was used for World War II air-raid shelters to resist cracks and seepage, water and moisture, and has been used for more than 100 years.

Compared with the waterproofing material structure of membrane coatings, Kolo self-waterproofing does not require base surface treatment, and there is no cross-operation and construction damage, so there is no need for leveling layer and protective layer. Labor and time are saved, which in turn saves costs and construction periods. The key is:

The material is inorganic and does not age, and the material is mixed with Kolo to solve the temperature shrinkage cracking, increase the workability of concrete, and avoid concrete honeycomb, holes, and hemp surface. The external spray Kolo DPS material reacts with the concrete to seal the concrete structure and make the concrete thicker. It solves the problems that the coil is easy to fail, the coil is easy to age, and the symptoms are not cured.

The structure is self-waterproof.

Kolo is waterproof. Kolo is waterproof.

1. Kolo doped products: introduction of Kolo anti-crack and anti-seepage agent.

The product is liquid and can be directly mixed into the concrete batching plant (the dosage is about 8 kg according to 2% of the cementitious material, 1 cubic meter).

After mixing, the concrete is pumped without obstruction, segregation, and water secretion, and can meet the requirements of almost self-compacting concrete. (For the mixing plant, the expansion agent and pumping agent can be omitted). The poured concrete has no honeycombs, holes, hemp surfaces, etc.

More importantly, it can solve the temperature cracks and dry shrinkage of concrete. Improve the compressive strength and flexural strength of concrete in the later stage.

It is very suitable for bridges, tunnels, high-speed railways, subways, sewage plants, hydropower stations, etc.

Pro, hello, I am glad to answer for you: what are the main waterproof materials used in construction projects, pro: there are many varieties of waterproof materials, which are divided into 4 categories according to their main raw materials:

Asphalt waterproofing material. Asphalt linoleum, paper tire asphalt linoleum, solvent-based and water-emulsion asphalt or asphalt rubber coatings and ointments made of natural asphalt, petroleum asphalt and coal asphalt as the main raw materials have good adhesion, plasticity, water resistance, corrosion resistance and durability. Rubber and plastic waterproof materials.

With neoprene, butyl rubber, EPDM rubber, polyvinyl chloride, polyisobutylene and polyurethane simple branches and other raw materials, it can be made into elastic tireless waterproof membrane, waterproof film, waterproof coating, coating material and ointment, cement, waterstop and other sealing materials, with high tensile strength, elasticity and elongation, good adhesion, water resistance and weather resistance, etc., can be used cold, long service life. Cement-based waterproofing materials. Admixtures that have the effect of promoting coagulation and compacting of cement, such as waterproofing agents, aerating agents and expansion agents, can enhance the hydrophobicity and anti-mold permeability of cement mortar and concrete; The coagulant mortar with cement and sodium silicate as the base material can be used for plugging and waterproofing underground projects.

Metal-based waterproof materials. Thin steel plates, galvanized steel plates, profiled steel plates, coated steel plates, etc. can be directly used as roof panels for waterproofing. Thin steel sheets are used for metal waterproofing in basements or underground structures.

Thin copper plates, thin aluminum plates, and stainless steel plates can be made into waterstops for building deformation joints. The joints of the metal waterproof layer should be welded and coated with anti-rust protective paint. —Excerpt.

Structural self-waterproofing is to adjust the mix ratio of structural concrete or add admixtures to improve the compactness, impermeability and corrosion resistance of concrete, meet the impermeability requirements of the design for underground buildings, and achieve the purpose of waterproofing. Understand what is structural self-waterproofing, so how to do structural self-waterproofing.

FDS-A source water structure self-waterproof material is a high-tech product independently developed on the basis of absorbing foreign advanced technology, and is a special waterproof material mixed with concrete. It has the ability to promote the interface activity of cement particles and superior waterproof performance, absorb calcium hydroxide in the chemical reaction with cement and water, and react to form calcium silicate colloid, which fills the void part occupied by water and air, forms self-healing properties, increases the compactness of concrete, and makes concrete produce the effect of waterproofing and micro-crack repair of its own body structure.

The structural self-waterproofing material has the ability to resist seawater erosion. Improve and improve the waterproof performance of concrete. Reduce crack shrinkage, enhance strength and compactness in the middle and late stages.

According to the waterproof material, the waterproof material is suitable for all underground concrete structures, reservoirs, pools, tanks, subways, tunnels, bridges, sea, water buildings, roofs, walls, bathrooms, water garden waterproofing projects and other waterproof and impermeable projects suitable for concrete pouring. What to look at is the structural self-waterproof construction plan.

Material ratio: 6% of the cement weight ratio is mixed into the use, and the maximum amount is not more than 25% of the cement weight ratio. The metering control of the concrete batching plant is used for full dry mixing, and then water is added to stir evenly. (The amount of concrete per cubic meter is about 20kg).

Steps: Yellow sand + source water through the structure from A-type waterproof material + coarse aggregate + cement fully stirred + add water to stir.

Base surface treatment: Before pouring, the debris should be cleaned up. Regarding the base surface treatment, you can refer to the waterproof technology column of the poly ace waterproof net, and there is a detailed explanation of why the base surface treatment should be carried out when doing waterproofing.

Curing: the curing conditions of concrete are very important for strength, crack resistance, impermeability, concrete pouring should be avoided direct sunlight, 8 hours of initial setting after the maintenance of scattered water, can use plastic film, geotextile cover insulation. (7 days).

No matter what kind of waterproof project, in order to ensure the quality of construction, it is best to choose well-known brand waterproof materials, to the regular building materials market to buy, compliant waterproof materials to achieve the ideal waterproof purpose.

The code divides buildings into four categories as follows:

A type of building is a building of special importance, such as a museum, a library, a memorial hall, an exhibition hall, a file gallery, and a laboratory of special importance.

Waterproof durability 25;Waterproof fortification requirements: three or more fortifications.

Category II buildings are important buildings. Such as terminals, station terminals, star-rated hotels, theaters, hospitals, shopping malls, and warehouses for storing important substances. Waterproof durability 15;Waterproof fortification requirements: two fortifications.

The three types of buildings are ordinary industrial and civil buildings. Such as office buildings, residences, industrial plants, school buildings and general warehouses. Waterproof durability 10;Waterproof fortification requirements: a fortification.

Most of the four types of buildings are buildings that need to be demolished in three or five years or have very low requirements for waterproofing. Such as sheds, building parts processing sheds, car and bicycle sheds, warehouses, etc. Waterproof durability 5;Waterproof fortification requirements: a fortification. Polyurethanes.

Polyurethane waterproof coatings. Polyurethane coating is known as "liquid rubber" and is one of the waterproof coatings with the best comprehensive performance. The coating film has toughness, high tensile strength, good elongation, corrosion resistance, strong resistance to structural expansion and deformation, and has a long service life.

But there is a smell, and black is not environmentally friendly.

Acrylics. Acrylic waterproof coating is a one-component, environmentally friendly elastic waterproof coating. It is based on self-crosslinking pure acrylic emulsion, combined with special modifiers, functional additives and fillers through dispersion and research. This kind of material is non-toxic, harmless, non-flammable, and is a green and environmentally friendly product; It has good elongation and tensile strength, pure acrylic has very good aging resistance, and the service life of the waterproof layer is also very long; Moreover, the construction is convenient, and the roller coating and scraping coating can be constructed.

The waterproof layer forms a continuous elastic membrane at the joint, which is particularly convenient for the construction of special-shaped parts with complex structures. Due to its relatively stable performance characteristics, the application effect is ideal, moderate, polymer cement.

Polymer polymer cement waterproof coating (referred to as JS waterproof coating) is a two-component waterproof material with both rigidity and flexibility. This kind of material is environmentally friendly, non-toxic and tasteless, has good air permeability, firm adhesion to the substrate, and dries quickly, but it is mostly a two-component material, which needs to be guided by the manual to mix liquid and powder. In addition, if too much talcum powder is added to the powder, the material performance is often greatly reduced, in order to avoid buying inferior products, it is still necessary to choose formal channels to buy brand products.

It is mainly used in home decoration.

Cement mortar.

Mortar waterproof coating is a two-component water-based waterproof mortar composed of organic emulsion material composed of acrylic emulsion and a variety of fillers, with inorganic powder composed of special cement and a variety of fillers, and formulated in a certain proportion. This kind of coating is non-toxic and harmless, non-polluting, it is really environmentally friendly coating, it can be directly constructed on the concrete surface and firmly bonded, easy to construct, not limited by the moisture content of the base layer, fast drying, short setting time, 2 hours after the construction can be pasted on the surface of the tile. However, due to the fact that this kind of material is a rigid waterproof coating, it lacks elasticity after film formation, and will affect the waterproof effect due to the sinking and dislocation of the building, and is generally suitable for parts with relatively stable structure.
