  2. Retaining wall - Wikipedia

    en.wikipedia.org/wiki/Retaining_wall

    It is important to have proper drainage behind the wall in order to limit the pressure to the wall's design value. Drainage materials will reduce or eliminate the hydrostatic pressure and improve the stability of the material behind the wall. Drystone retaining walls are normally self-draining.

    While quite different in the manufacture or configuration than geonets are competitive geosynthetic products called geospacers. Their drainage cores consists of nubs, columns, cuspations, or 3-D networks of stiff polymer strands. They are generally used for drainage behind retaining walls, plaza decks or green roofs. [1] Various categories of ...

    en.wikipedia.org/wiki/Drainage

    If the water pressure is not drained appropriately, retaining walls can bow, move, and fracture, causing seams to separate. The water pressure can also erode soil particles, leading to voids behind the wall and sinkholes in the above soil. Traditional retaining wall drainage systems can include French drains, drain pipes or weep holes. To ...

    The second type is in the form of drainage panels, the rigid polymer core being nubbed, columned, dimpled or a three-dimensional net. With a geotextile on one side it makes an effective drain on the backfilled side of retaining walls, basement walls and plaza decks. The cores are sometimes vacuum formed dimples or stiff 3-D meshes.

  6. Land drains - Wikipedia

    en.wikipedia.org/wiki/Land_drains

    The purpose of land drains in building construction is somewhat different. If voids are created in the ground for any reason they tend to fill with water. Also the static loads on any subterranean structure and retaining walls can be massively increased by the presence of water in the surrounding ground.

  9. Soil nailing - Wikipedia

    en.wikipedia.org/wiki/Soil_nailing

    Soil nail components may also be used to stabilize retaining walls or existing fill slopes (embankments and levees); this is normally undertaken as a remedial measure. Since its first application using modern techniques in Versailles in 1972, [ 2 ] soil nailing is now a well-established technique around the world.
