Retaining Walls – Its Types and Its Importance First things first, you must know that a retaining wall is constructed mainly to prevent the lateral pressure of the soil and other materials in other words it acts as a barrier. The functional purpose of building a retaining wall is prevent a piece of land from collapsing onto different establishments or perhaps in a certain area. Backfill is the term given to the materials that is being retained. It could also be used as a verb that describes the act of putting more dirt at the rear of the wall to make sure the ground is level. If by any chance you have a contoured area then you might consider using retaining walls not just for functional purposes but also for aesthetic reasons. 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. The choice of retaining wall will depend on the following factors: the expenses, the qualities of the soil, the height of the wall as well as the conditions of the ground water.

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 a rule of the thumb to check the standards and rules in building establishments prior letting your people work on a retaining wall project, be it four feet below or more. 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. Majority of the force that the retaining wall must tolerate comes from the backfill. It is of great importance to determine first the pressure of exerted by the backfill, this is possible by studying the ground water levels, the type of soil, the slope of the soil and the weight of the soil unit. 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 want to go through those steps then it would be best if you 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 – Getting to Point A
