  2. Permeable paving - Wikipedia

    en.wikipedia.org/wiki/Permeable_paving

    Unlike a full-depth porous asphalt pavement, OGFCs do not drain water to the base of a pavement. Instead, they allow water to infiltrate the top 3/4 to 1.5 inch of the pavement and then drain out to the side of the roadway. This can improve the friction characteristics of the road and reduce road spray. [27]

  3. Tremie - Wikipedia

    en.wikipedia.org/wiki/Tremie

    The tremie concrete placement method uses a vertical or nearly vertical pipe, through which concrete is placed by gravity feed below water level. [4]The lower end of the pipe is kept immersed in fresh concrete so that concrete rising from the bottom displaces the water above it, thus limiting washing out of the cement content of the fresh concrete at the exposed upper surface.

  4. Pervious concrete - Wikipedia

    en.wikipedia.org/wiki/Pervious_concrete

    A pervious concrete street in 2005. Pervious concrete (also called porous concrete, permeable concrete, no fines concrete and porous pavement) is a special type of concrete with a high porosity used for concrete flatwork applications that allows water from precipitation and other sources to pass directly through, thereby reducing the runoff from a site and allowing groundwater recharge.

  5. Canal lining - Wikipedia

    en.wikipedia.org/wiki/Canal_lining

    Concrete used for canal lining is typically non-reinforced, as a way to reduce cost. A common method for constructing concrete lining is the use of slip forms, which are drawn down the length of the canal as the concrete is poured. [3] Hand laying of concrete or prefabricated sections are also used when only a short distance needs to be covered ...

  6. Hydrophobic concrete - Wikipedia

    en.wikipedia.org/wiki/Hydrophobic_concrete

    If the surface requires another coat, it must be applied within forty eight hours of the initial application of the hydrophobic mixture. Once applied, the concrete must cure in a moist environment two to three hours after the application. This is achieved by spraying the surface with water at least three times a day for a few days.

  7. Basement waterproofing - Wikipedia

    en.wikipedia.org/wiki/Basement_waterproofing

    Water seepage in basement and crawl spaces usually occurs over long periods of time and can be caused by numerous factors. Concrete is one of the most commonly used materials in home construction. When pockets of air are not removed during construction, or the mixture is not allowed to cure properly, the concrete can crack, which allows water ...
