Retaining walls are walls built into sloping terrain that stop the earth from moving downward. Using retaining walls, one can make usable areas out of hilly ground, such as flat gardens and terraces and some, especially brick and stone walls, are popular for landscape use. They usually greatly improve the value of what was a previously constantly eroding backyard. There are several different designs of retaining walls.
Gravity wall – Built using masonry blocks, paved stone or concrete, gravity walls hold back the soil simply from their own weight, or gravity. This type of wall will usually have a sloping front to help support the wall. Homeowners often prefer gravity walls for landscape use because the stone rocks and paved bricks used to build them looks better than some of the other industrial options.
Cantilevered wall– Built in the shape of an inverted T, these walls use steel-reinforced concrete and steel beams cantilevered from the bottom to support the weight of the wall. Overall, this approach uses less materials than gravity walls. This type is often used for large basements of homes.
Piling wall – Built from steel beams or wooden planks, these walls are driven straight into the ground and can be used to hold back soft soil. Also, anchors can be placed behind these walls to help hold them up in case of a partial soil collapse.
Drainage – Once a wall is built, the area's natural drainage system is blocked. Therefore, when constructing retaining walls, a draining system must be designed for the soil behind the wall to keep hydrostatic pressure in check and maintain healthy soil. Failure to do so could result in an eventual collapse of the wall.
Retaining walls are structures that are designed to help reinforce soil, or resist the lateral pressure of soil. They alter the ground elevation, and apply pressure in order to create a wall or barrier. The height of retaining walls varies, as does the materials used to create them. While a contractor may build one retaining wall from concrete, another one may be built from materials like wood or rock. These walls are installed in a number of yards, public gardens, and other landscaped areas across the United States.
There are all kinds of retaining walls built from materials like brick, steel, concrete, or stone. These walls not only block soil, but they also prevent erosion. Usually a licensed contractor, masonry worker, or landscaper will build retaining walls for clients and businesses. These reinforced structures must be able to support and block the soil they are built against. Depending on the design and purpose of the wall, these may be constructed from timber materials, or may require something heavier such as bricks with mortar in order to provide ample strength. Often the top of retailing walls are level with the ground, but it just depends on the environment it is built in. Some of the other factors contractors must consider when building these structures are gravity, weather conditions, and wall height.
