Waterproofing injection: description and reviews

If mistakes were made during the construction of the building, this could cause a violation of the waterproofing, which leads to the destruction of the foundation and the structure itself. To date, new technologies are known, with the help of which it is possible to solve these problems qualitatively and quickly. However, you must be prepared for the fact that not all of them are available for home use, because, for example, the injection method requires the use of pumping equipment.

Waterproofing is an effective method of protection from exposure to moisture. It allows you to treat leaks, which can be pressure. The principle of the method consists in pumping waterproofing materials under high pressure with the help of pumping equipment, which is intended for this purpose.

Need to use injection waterproofing

The foundation acts as the foundation of any building. Its quality depends on the life of the house. For this reason, at the initial stage of construction it is important to approach the waterproofing of the foundation as seriously as possible. These manipulations can protect the house from groundwater and rainwater, making it as resistant to corrosion as possible.

One of the possible options for protecting the foundation during the operation phase, as mentioned above, is the injection waterproofing. If a capillary rise of groundwater occurs between the wall and the foundation, then the space begins to fill with moisture. Capillary moisture is able to saturate the structure at 10 m in height, which is harmful also because the water can be saturated with acids and aggressive salts.

When operating the building it is important to monitor its condition, providing reliable waterproofing of concrete underground structures. Such control is difficult to implement because of the inaccessibility of waterproofing, because it is hidden by massive elements, backfill, etc. In this case, it is effective to use waterproofing materials that have a penetrating effect.

Description of injection waterproofing

Waterproofing injection allows the building not to lose its strength due to the fact that the structures are kept dry, the reinforcement is passivated, initiation of corrosion processes occurs at a lowered pH level. There are several ways to stop corrosion of the armature, among them it is necessary to distinguish the sweep and coating with special compounds. Solve the problem by changing the operating conditions.

It is physically impossible to clean the reinforcement, because it is encased in concrete. It remains possible only one option to increase the level of LV for a long time, because corrosion will be restored when infiltration of moisture. Waterproofing injection protects the structure from the effects of water. The principle of the substances is very simple: they penetrate into the upper porous layer and fill the pores, displacing the liquid.

Additional Features

If a component is added to the solution, it is possible to achieve properties, among which:

• Fighting with fungus and mold;
• Increase chemical stability of the structure;
• Restoration of technical properties of old materials;
• The elimination of the risk of new corrosion on the valve.

Feedback on injection waterproofing

According to consumers, the main advantage of injection waterproofing is its durability. The materials have excellent technical qualities, they are able to protect the structure from moisture, corrosion and temperature changes, keeping the heat in the building. Work is often done using liquid rubber or liquid glass. According to buyers, each of these materials has its advantages, for example, liquid rubber is flexible and highly elastic. It is simply applied, it is environmentally safe and has high adhesion.

Liquid rubber, in the opinion of home masters and specialists, is quite easy to repair. Special skills to use this material will not be required.

Features of liquid glass

Liquid glass is also quite common for injections. It is able to protect structures from exposure:

• The sun;
• Corrosion;
• Wind;
• Temperature.

According to users, liquid glass has one important drawback, which is expressed in the fragility of the material. He is ready to serve for only 5 years.

Reviews about different materials for injection waterproofing

Injection waterproofing can be carried out using different materials, among them it should be noted:

• Epoxy products;
• Micro cement;
• Polyurethane materials;
• Acrylate gels.

According to consumers, polyurethane materials and acrylate gels are the most effective. They have a high plasticity, and with non-uniform loads do not collapse. The formulations are hydro-reactive, this indicates that they polymerize under the influence of water. As for acrylate gels, their density is almost the same as the density of water. In the soil and the material of the construction, they quickly solidify, forming a strong bond.

Consumers like that these solutions allow you to control the polymerization reaction time. This helps to block access to water flows penetrating underground structures. Provide protection from pressurized water can be in the walls of the structure and between the ground and walls. The material is able to strengthen the layers of soil, mixing with its particles, this allows you to get protection from washing out and stabilizes the soil of the building.

If you will be injected waterproofing basement, you should pay attention to polyurethane polymers. According to consumers, they are among the most economical. This is due to the fact that when exposed to moisture, the volume of material increases by 20 times. This property is especially important in the installation of waterproofing in conditions of loose soils and quicksands.

The material starts foaming and displaces the water when it comes into contact with moisture. When applying the next portion of waterproofing in the absence of water, it hardens without foaming and becomes a strong dense substance that forms an impermeable shell.

Alternative solutions

Quite often buyers compare epoxy compounds with polyurethane mixtures and acrylic gels. The former are polymerized in air, and if water is present, it can adversely affect the characteristics. But after solidification, the material exhibits the best waterproofing qualities, protecting the structure from moisture and giving it mechanical strength.

Injection waterproofing of the foundation is often carried out with the help of micro cement, which, according to consumers, penetrates well into cracks and voids, crystallizes and forms a protective barrier that does not allow moisture to pass through. In liquid form, the injectable formulation is within 15-40 minutes. The solidification can be controlled by the catalyst contained in the mixture.

Reviews on insulation technology

Injection waterproofing of the cellar from the inside of the groundwater, according to the home masters, should be carried out using a special technology. In the first stage, it involves drilling holes. The distance between them should be 50 cm, and use in the process of these manipulations requires a puncher. The diameter of the holes should be equal to the limit of 1 to 2 cm.

It is important to make holes through if you want to form a waterproof layer from the outside. To repair defects, cracks and breaks, holes should be made not clear. If you plan to use a hydro-reactive material, then the holes are pre-wetted with water. When an injection waterproofing of walls is carried out , consumers are advised to act on the same technology. At the next stage, it involves pumping the composition into drilled grooves. Then you can carry out measures to neutralize salts and protect from mold and fungus. The surface is covered with plaster at the final stage.

Conclusion

Penetrating injection waterproofing has a fairly wide scope of use. With the help of such materials, it is possible to waterproof cold and deformation seams, to perform anti-capillary cut-off in brick and concrete walls, and to stop pressure leaks. Materials are quite expensive, which limits the scope of their use. Quite often, this method of waterproofing is used only when it is necessary to protect against moisture from large structures, and also when other methods are impossible or even more expensive.
