Retaining walls are artificial structures that resist soil pressure in the event of a ground change greater than the angle for repose. Well-built walls will support sloped ground and reduce water pressure. Visit retaining wall san diego before reading this.
These structures are most commonly a cantilever, which is an unsupported barrier at the top. Normal retaining walls extend past grade level to one side while holding back another grade. These walls need to be constructed and planned so they will withstand the pressures of both soil and groundwater. A retaining wall that has been anchored into the slope is another notable option. To reinforce an existing retaining-wall, soil nails can be used. This technique can be used to build walls and stabilize slopes. This method of soil reinforcement involves the use of steel tendons, which are then drilled into and grouted in to the soil.
Placement of retaining walls requires careful planning and consideration. The sole objective is to limit the movement of soil due to gravity. As the walls are built, pressures increase from the top to the base. Due to the difference between the forces acting on the wall surface, improper installation can lead to a wall tipping over or causing a complete collapse.
You can build a wall using many different materials. These include wood, concrete, and stone. Material and height are decided by a variety of factors. Materials and placement of walls are influenced by a number of factors, including the height proposed, the soil type to be kept behind the wall and its angle. Also, if any large objects are on the slope such as structures, vehicles or other heavy items, this is also a factor. The soil should also have a drainage plan in place. If the soil soaks up moisture due to rain, or from irrigation of the ground, then the pressure placed on the retaining walls increases dramatically. A wall that is not properly drained will become more prone to collapsing or sliding.
Parking lots and driveways are the two most common applications for these walls, but you can also use them to create outdoor patios or surround an in-ground swimming pool. If the property has a commercial or residential use, there are times when the contours in the landscape restrict the choices for driveway routes or size or elevation of parking areas. The wall allows parking spaces and driveways to be built where otherwise they wouldn’t.
