The Importance of Functionality:
Retaining walls are permanent structures that separate lower land from higher land. They are barriers that hold back soil from above, as on a hillside, which might otherwise cave in, erode, or slide into the lower area.
In some instances, especially walls over 3-4 feet, the plan will require engineering, soil testing, geo-grid reinforcement, and even surveying so a proper retaining wall can be installed. Geo-grid is an industrial strength material in the form of a net that is installed during wall construction to add further strength, permanence and safety. Often overlooked by contractors, it can make all the difference. Any and all of this we can take care of.
Importance of retaining walls
In hilly areas like the Atlanta area, retaining walls are an integral part of the design for a landscaped area, and might be the first thing considered when constructing beautiful backyard areas (or front yards). Afterwards the patios, the walkways, the arbors, the landscaping, the outdoor fireplace , and other design and lifestyle elements can be added.
Design features of retaining walls
Many times a wall may need to be wired for lighting, and often the plan for walls needs to take into account drainage concerns. Hydrostatic pressure, water building up behind the wall, will ruin the wall without the proper construction techniques we employ to allow for water to drain away.
Other types of walls may be employed. Dry stacked boulders may be used. We are experienced in the use of this type of wall, and it may be all the functionality required for some sites. This is a less expensive option, Hydrostatic pressure is not a problem in this type of wall as in mortared walls. Water can drain through, and for some scenarios this is not an issue.
Construction of Retaining Walls
Retaining walls are typically built with stone, brick, cinder blocks, or concrete. Often we use interlocking or modular block. We like some of these benefits of this material: strength, longevity, flexibility of design, and appearance. Other materials, even marble, limestone, granite, or stacked stone might be used depending on the desired look.
And depending on that desired look, retaining walls might be made of cinder blocks coated with stucco or veneered with the desired material (perhaps flagstone).
