A basement wall is thus one kind of retaining wall; however, the term usually refers to a cantilever retaining wall, which is a freestanding structure without lateral support at its top. [2] These are cantilevered from a footing and rise above the grade on one side to retain a higher level grade on the opposite side.
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 ...
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.
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 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.
A rope of up to 12 inches (30 cm) in length is placed in the joints. The other end of the rope is extended up into the cavity wall. The cotton can absorb the moisture inside the wall and wick it to the outside, but the converse is also true - it is possible for the cotton rope to wick a small amount of moisture from the outside to inside the wall.
