Modern technologies of water repellency from concrete surfaces can be used to protect and preserve concrete structures from the negative effects of moisture, chemicals, salts and other aggressive environments. Such technologies can be especially useful for road infrastructure, bridges, underground parking lots, building walls and other concrete surfaces that are subject to wear and tear due to contact with water and various contaminants.
Below we will talk about some of the modern technologies that are used to repel water from concrete surfaces:
Hydrophobic impregnations
These are special substances that are applied to the surface of concrete to make a protective hydrophobic layer. This layer repels water and dirt, reducing their absorption into the concrete. Hydrophobizing impregnations can be based on silanes, siloxanes or silane-siloxanes.
Teknosil water repellent is a good example of such materials with features and specifications that you can find on the site.
Hydrophobic coating
These are thin films or coatings that are applied to the concrete surface. They create a hydrophobic barrier surface that helps repel moisture and protect concrete from corrosion and wear.
Nanocomposites
The use of nanotechnology makes it possible to produce special nanocomposite materials that can interact with the concrete surface, forming hydrophobic structures at the molecular level.
Self-cleaning coating
These technologies are based on the properties of self-cleaning surfaces. For example, the application of titanium dioxide nanoparticles to the surface of concrete helps to decompose contaminants under the action of sunlight, keeping the surface clean.
Hydrophobic additives for concrete
When mixing the concrete mixture, special hydrophobic additives can be added that provide the concrete with water-repellent properties at the material level.
For example, Teknomer 120 concrete admixture is a high quality hydrophobic admixture that provides concrete protection against both positive and negative water pressure. In addition to its main function, this material increases the strength and frost resistance of concrete.
Some technologies can be used on both new concrete surfaces and existing ones, helping to increase their lifespan, reduce maintenance costs and improve weather resistance. However, before using any technology, appropriate technical studies should be carried out and experts should be contacted to select the optimal solution depending on specific conditions and needs.
