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. To date, new technologies are known that can be used to quickly and efficiently solve these problems. 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 injection waterproofing. It allows you to treat leaks, which can be pressure. The principle of the method is to pump waterproofing materials under high pressure using pumping equipment that is designed for this.
Need to use injection 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 seriouslyapproach the waterproofing of the base. These manipulations allow you to 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 a structure up to 10 m in height, which is also harmful because water can be saturated with acids and aggressive s alts.
During the operation of the building, it is important to monitor its condition, ensuring reliable waterproofing of concrete underground structures. Such control can be difficult to exercise 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 the corrosion of reinforcement, among them cleaning and coating with special compounds should be distinguished. You can solve the problem by changing the operating conditions.
It is physically impossible to clean the rebar, because it is enclosed in concrete. There is only one option left to upgrade.pH level for a long time, because corrosion will be resumed with moisture infiltration. Injection waterproofing perfectly protects the structure from the effects of water. The principle of the 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;
- improving the chemical resistance of the structure;
- restoring the technical properties of old materials;
- eliminate the risk of new corrosion on rebar.
Injection waterproofing reviews
According to consumers, the main advantage of injection waterproofing is its durability. The materials have excellent technical qualities, they are able to protect structures from moisture, corrosion and temperature changes, keeping heat in the building. Work is often carried out using liquid rubber or liquid glass. According to buyers, each of these materials has its own advantages, for example, liquid rubber is flexible and highly elastic. It is easy to apply, environmentally friendly and highly adhesive.
Liquid rubber, according to home craftsmen and specialists, is quite easy to repair. No special skills are required to use this material.
Featuresliquid glass
Liquid glass is also quite common when injecting. It is able to protect structures from impact:
- sun;
- corrosion;
- wind;
- temperature.
According to users, liquid glass has one important drawback, which is expressed in the fragility of the material. It is ready to serve for only 5 years.
Reviews on different materials for injection waterproofing
Injection waterproofing can be carried out using different materials, among them should be highlighted:
- epoxy;
- microcements;
- polyurethane materials;
- acrylate gels.
According to consumers, polyurethane materials and acrylate gels are the most effective. They have high ductility, and do not collapse under uneven loads. The compositions are hydroreactive, which indicates that they polymerize under the influence of water. As for acrylate gels, their density is almost the same as that of water. In soil and structural material, they quickly harden, forming a strong bond.
Customers love that these solutions allow you to control the polymerization reaction time. This helps block access to water flows penetrating underground structures. It is possible to provide protection against pressure water in the walls of the structure and between the soil and the walls. The material is able to strengthen the layers of the soil, mixing with its particles, this allows you to get protection against leaching and stabilizes the soil of the building.
If you will carry out injection waterproofing of the basement, then 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 the material increases by 20 times. This property is especially important when waterproofing in conditions of loose soils and quicksand.
Material begins to foam and displaces water upon 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 polymerize in air, and if water is present, it can adversely affect performance. But after hardening, the material exhibits better waterproofing qualities, protecting the structure from moisture and giving it mechanical strength.
Injection waterproofing of the foundation is quite 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. Curing can be controlledcatalyst contained in the mixture.
Feedback on insulation technology
Injection waterproofing of the basement from the inside from groundwater, according to home craftsmen, should be carried out using a special technology. At the first stage, it involves drilling holes. The distance between them should be 50 cm, and a perforator must be used in the process of these manipulations. The diameter of the holes must 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 breaks, the holes should be made non-through. If you plan to use hydroreactive material, then the holes are pre-wetted with water. When injectable waterproofing of walls is carried out, consumers are advised to use the same technology. At the next stage, it involves pumping the composition into the drilled recesses. Next, you can take measures to neutralize s alts and protect against mold and fungus. The surface is covered with plaster at the final stage.
Conclusion
Penetrating injection waterproofing has a fairly wide range of uses. With the help of such materials, it is possible to waterproof cold and expansion joints, carry out anti-capillary cut-off in brick and concrete walls, and also 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 aswhen other methods are impossible or even more expensive.
