The drainage system collects any water entering the basement and drains it to an internally placed sump pump system, which will then pump the water out of the basement. The Federal Emergency Management Agency (FEMA) recommends basement waterproofing with a water alarm and "battery-operated backup pump" as a preventive measure against the high ...
Example of flat piece of concrete having dislodged with corroded rebar underneath, Welland River bridge across Queen Elizabeth Way in Niagara Falls, Ontario. The expansion of the corrosion products (iron oxides) of carbon steel reinforcement structures may induce internal mechanical stress (tensile stress) that cause the formation of cracks and disrupt the concrete structure.
Water will often penetrate the outer envelope of a building and appear inside. Common defects include: Roof defects such as faulty flashing, cracked or missing slates or tiles. Faults in the brickwork or masonry such as missing or cracked pointing. Porous bricks or stones. Missing or defective mastic around windows and doors. Blocked weep holes.

This kind of concrete is also known as self-repairing concrete. Because concrete has a poor tensile strength compared to other building materials, it often develops cracks in the surface. These cracks reduce the durability of the concrete because they facilitate the flow of liquids and gases that may contain harmful compounds.
When creating hydrophobic concrete through a coating process, a coating is sprayed or brushed onto a porous surfaces. In most cases, it is applied to a regular concrete slab that then undergoes a corrosive process to expose more of the concrete's capillaries. This can be achieved by water blasting the surface at about 3,000-4,000 psi.
