Waterproofing cisterns with water repellent

Water repellents are compounds that use the hydrophobic effect to prevent the absorption of water by the protected material. Porous materials, such as concrete, absorb water and get saturated, ultimately leading to leaks and dampness. This will cause the deterioration of the building and even health hazards due to mold and bacteria.
With water repellent we can prevent all these problems. You can also be used in swimming pools, fountains, canals, reservoirs, lift pits, basements, tunnels, galleries, etc. and any other structure that is subject to a great hydrostatic pressure.
