If mistakes were made during the construction of the building, this can cause a violation of the waterproofing, which leads to the destruction of the foundation and the structure itself. Today, new technologies are known with the help of which these problems can be quickly and efficiently resolved. However, you should 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.
A fairly effective method of protection against moisture is injectable waterproofing. It allows you to treat leaks, which can be pressure head. The principle of the method is to pump waterproofing materials under high pressure using pumping equipment that is designed for this.
The need for injectable waterproofing
The foundation acts as the foundation of any building. The life of the house depends on its quality. For this reason, at the initial stage of construction, it is important to approach the base waterproofing as seriously as possible. These manipulations help 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 injection waterproofing. If a capillary rise of groundwater occurs between the wall and the foundation, then the space will begin to fill with moisture. Capillary moisture can saturate the structure by 10 m in height, which is also harmful because the water can be saturated with acids and aggressive salts.
When operating a building, it is important to monitor its condition, providing reliable waterproofing of concrete underground structures. Such control can be difficult to implement due to the inaccessibility of waterproofing, because it is hidden by massive elements, backfill, etc. In this case, the use of waterproofing materials that have a penetrating effect is effective.
Description of Injection Waterproofing
Injection waterproofing allows the building not to lose strength due to the fact that the structures are kept dry, the reinforcement is passivated, and corrosion processes are initiated at a low pH level. There are several ways to stop reinforcement corrosion, among them stripping and coating with special compounds should be highlighted. You can solve the problem by changing the operating conditions.
It is physically impossible to clean the reinforcement, because it is enclosed in concrete. It remains possible only one option to increase the pH level for a long time, because corrosion will be resumed during moisture infiltration. Injection waterproofing excellently protects the structure from the effects of water. The principle of operation of substances is very simple: they penetrate the upper porous layer and fill the pores, displacing the liquid.
Additional features
If any component is additionally introduced into the solution, then properties can be achieved, among which:
- fight against fungus and mold;
- increase the chemical resistance of the structure;
- restoration of technical properties of old materials;
- eliminating the risk of new corrosion on the valve.
Injection waterproofing reviews
According to consumers, the main advantage of injectable waterproofing is its durability. The materials have excellent technical qualities, they are able to protect structures from moisture, corrosion and temperature changes, while maintaining heat in the building. The work is often carried out using liquid rubber or liquid glass. According to customers, each of these materials has its own advantages, for example, liquid rubber is flexible and highly elastic. It is easy to apply, it is environmentally friendly and has high adhesion.
Liquid rubber, according to home masters and specialists, is quite simple to repair. Special skills to use this material will not be required.
Features of liquid glass
Water glass is also quite common when injecting. 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 only for 5 years.
Reviews of different materials for injection waterproofing
Injection waterproofing can be carried out using different materials, among them should be highlighted:
- epoxy agents;
- microcements;
- polyurethane materials;
- acrylate gels.
According to consumers, the most effective are polyurethane materials and acrylate gels. They have high ductility, and with uneven loads are not destroyed. The compositions are hydroreactive, 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 material of construction, they quickly harden, forming a strong bond.
Consumers like these solutions to control the polymerization reaction time. This helps to block access to water flows entering underground structures. Protection against pressure water can be provided in the walls of the structure and between the ground and walls. The material is able to strengthen the soil layers, mixing with its particles, this allows you to get protection from leaching and stabilizes the soil of the building.
If you will be injecting basement waterproofing, you should pay attention to polyurethane polymers. According to consumers, they are one of 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 when waterproofing in the conditions of loose soils and quicksand.
The material begins to foam and displaces water upon contact with moisture. When applying the next portion, the waterproofing in the absence of water, it hardens without foaming and becomes a strong dense substance, which forms an impenetrable shell.
Alternative solutions
Quite often, buyers compare epoxy compounds with polyurethane mixtures and acrylic gels. The first polymerize in air, and if water is present, then it can adversely affect the performance. But after hardening, the material shows the best waterproofing qualities, protecting the structure from moisture and giving it mechanical strength.
Injection waterproofing of the foundation is often carried out using microcement, 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 injection composition is within 15-40 minutes. Hardening can be controlled by the catalyst contained in the mixture.
Insulation technology reviews
Injection waterproofing the basement from the inside from the groundwater, according to home masters, should be carried out using special technology. At the first stage, it involves drilling holes. The distance between them should be 50 cm, and use a perforator in the process of these manipulations. 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 on the outside. To repair defects, cracks and kinks, holes should be made through and through. If you plan to use hydroreactive material, then the holes are pre-wetted with water. When injecting waterproofing walls, consumers are advised to act on the same technology. At the next stage, it involves pumping the composition into the drilled recesses. Further, you can take measures to neutralize salts and protect against mold and fungus. The surface at the final stage is covered with plaster.
Conclusion
Penetrating injectable waterproofing has a fairly wide area of use. With the help of such materials, it is possible to waterproof cold and expansion joints, to perform anti-capillary cut-off in brick and concrete walls, as well as to stop pressure leaks. Materials are quite expensive, which limits the scope of their use. Quite often, this waterproofing technique is used only when it is necessary to protect large structures from moisture, as well as when other methods are impossible or even more expensive.
