Retaining walls provide a practical way to control the erosion of land. They are the result of an earthen foundation or earth retaining material. Erosion is controlled by applying suitable pressure to the wall with a foot lever or rotating blade system. Retaining wall systems are designed to meet various needs in various landscapes. As a result, there is a large variety of these structures available in the market. In addition, they are made from different materials such as concrete, clay or stone.
Retaining walls are usually relatively rigid retaining walls located in Adelaide used primarily for supporting soil vertically on both sides so that it may be retained in different levels on both sides. Retaining walls vary in their heights. Usually, the ones used for low-sloping sites are constructed with small concrete pads of approximately 3 feet. The advantage of using these structures is that they preserve the topography and the slope of the land.
If the site is subject to a heavy downslope, low retaining walls may be used instead of the traditional block walls. These are typically constructed with a block and post pattern, where each block is driven into the ground with a foot lever. Backfills are constructed to include the backfill of soil. In some instances, backfills are used to support a sloped site. Backfills are normally located at the corner of the retaining wall.
Concrete footers are installed between the earth behind the retaining walls located in Adelaide and the footers. The footers are secured to the ground by mechanical devices such as steel plates. Severe weather conditions may cause the installation of temporary earth anchors to be used. Earth anchors are mechanical devices that are anchored to the soil below them.
Retaining wall blocks are fabricated from lightweight materials such as polyethylene and metal. The blocks are assembled by welding with corners joined by two pieces of galvanized steel. Some units are constructed to include a centre anchor or ball, while others are left with just a bottom and top bolt. Hydraulic jacks are used to lift and lower the blocks. Units that contain an earth anchor are more challenging to install than those containing a ball and centre anchor.
The cost of constructing retaining walls located in Adelaide is dependent on a number of factors. The amount of material needed will dictate the size and material used. The location of the retaining wall also plays a large role in its cost. Landscape designers can help determine the best materials for retaining walls by combining concrete block elements with natural and synthetic stucco to create a highly usable material.
