Retaining Walls – Its Types and Its Importance You might be wondering what is a retaining wall, well this is actually a structure that keeps the soil and other materials in place. The main purpose why they are built is to prevent corrosion and the collapse of an elevated piece of land from falling onto certain establishments or in a certain area. Backfill is the term given to the materials that is being retained. The term mentioned earlier could also refer to the act of putting more dirt behind the wall just to make sure that the entire ground is laid equally. If you happen to have contoured areas in your property then all you have to do is put up retaining walls for functional purposes and of course to elevate the appearance of those areas. If you have a very steep slope in your area then you can convert those with a more accessible and convenient way of getting on top and that is through terraced yard. The materials for building retaining walls vary as well as the methods employed in putting them up or for the set up. There are different factors that affects the choice of retaining wall, this includes the following: the price, the nature of the solid, the height of wall and the conditions of the ground water.
5 Key Takeaways on the Road to Dominating Resources
A license engineer is the only person who can approve a retaining wall that measures four feet and above, usually this is mandated in most cities of municipalities. It is also a must to know a thing or two about the standards for building a structure prior starting a retaining wall project, be it four feet long or below. Keep in mind that retaining walls must be safely structured on top of making it visually pleasing for people. The backfill that is found at the rear of the retaining wall exerts some kind of pressure called lateral earth pressure, the retaining wall on the other hand must be capable of withstanding such pressure. If the retaining wall is unable to withstand such pressure then everything will erode or collapse. If one wishes to determine what materials is appropriate to use in building the retaining wall, the pressure must first be determined, this is possible by studying the type of soil and its weight per unit, the level of ground water and the slope of the soil. With the help of those factors the engineers perform a number of calculations to determine what designs are appropriate to use as well as the suited materials for the wall. If you don’t indeed to follow those engineering steps then you must overdo things. It is completely understandable to require engineers intervention once the retaining wall project surpass four feet since any mistakes could lead to casualties moreover there are different methods that engineers employ in order to establish this project.The Essentials of Repairs – 101
