Water leakage is a common issue in buildings, especially in structural components such as walls, roofs, basements, water tanks, etc. Traditional waterproofing methods often lose their effectiveness over time due to cracks formed during the operation period of the structures, leading to water seepage. The new technology based on “reverse capillary” mechanism uses hydrophobic or superhydrophobic materials to repel water instead of absorbing it into the structure. A key advantage of this technology is its ability to effectively prevent water penetration even when hairline cracks appear. This new waterproofing technology not only prevents water from seeping into the structure like traditional solutions, but also repels water when the waterproofing material cracks. So that the structures can beprotected for a long time. Additionally, it can be applied easily, requires no advanced techniques, and has a long lifespan. This technology has great potential for widespread application in construction and maintenance, that helps to reduce repair and maintenance costs. Keywords: Waterproof
hydrophobic
superhydrophobic
forward capillary
reverse capillary.
