Dekguard CP

Destruction of concrete under temperature fluctuations

Temperature fluctuations are one of the most common causes of concrete strength loss. Porous concrete absorbs water, and when freezing, water expands in volume by approximately 9%, creating colossal internal hydrostatic pressure. As a result, internal microcracks appear, and the surface layer of concrete begins to flake and crumble. For example, in a situation where cold rain follows a heat wave, the surface of the concrete quickly heats up and cools down. A temperature difference arises between the surface and the internal layer of concrete. Due to thermal stress, a "web" of small microcracks forms, making it even easier for moisture to penetrate. The Dekguard CP coating creates a hydrophobic barrier, preventing water from entering the concrete. No water inside means there is nothing to expand when freezing. The coating is also vapor-permeable, meaning it does not allow water from the outside but allows water vapor to freely escape from the inside. After all, if moisture is "trapped" under an impermeable layer, during freezing, it will simply detach this coating along with pieces of concrete. It is worth adding that Dekguard CP is UV-resistant and designed for many years of exposure to sunlight without losing elasticity and protective properties.
