Retaining Walls
Erosion after heavy rain, unstable slopes, runoff, and difficult grade changes can leave sections of a North Atlanta property unusable or put added soil pressure near patios, driveways, walkways, and foundations. These problems are especially common where sloped terrain and Georgia's red clay soils affect how water moves through a property.
Miller Landscape designs and installs retaining walls to stabilize grades, manage elevation changes, and make challenging areas more functional. From structural walls and terraced hillsides to smaller garden walls, each project is designed around the property's slope, soil, drainage, surrounding structures, and intended use.
Retaining Wall Design & Installation
The right retaining wall depends on what the wall needs to accomplish and the conditions around it. A wall supporting a substantial slope requires different planning than a low wall defining a planting bed or separating two landscape elevations.Miller Landscape designs retaining walls for a variety of applications, including:
- Structural retaining walls that stabilize slopes and retain significant changes in elevation.
- Terraced retaining walls that divide steep terrain into usable levels for lawns, landscaping, pathways, patios, or other outdoor areas.
- Landscape and garden walls that manage smaller grade changes, create raised planting areas, or define different sections of the yard.
- Integrated retaining walls designed to coordinate with patios, walkways, and other outdoor living features.
When retaining walls are part of a larger landscape or hardscape project, we can coordinate their elevations, materials, and placement with nearby patios, walkways, planting areas, and other outdoor features.
Retaining Wall Materials & Systems
Miller Landscape selects retaining wall materials and systems based on the wall's purpose, site conditions, structural requirements, and desired appearance.Modular block retaining walls are suited to many residential applications and come in a range of sizes, textures, and colors. We use established manufacturers such as Belgard where appropriate, with individual products and collections covered in our dedicated product resources.
For walls requiring additional support, geogrid reinforcement can be incorporated into compacted soil behind the wall to improve stability. Its use depends on factors such as wall height, slope, soil conditions, and nearby loads.
Natural stone retaining walls provide a more organic appearance and can work well for garden walls, terraces, and grade transitions. Miller Landscape determines the appropriate material and wall system based on the function and conditions of each site.
How We Plan & Build Retaining Walls
A retaining wall should be designed around the property rather than selected solely by appearance. Miller Landscape begins by evaluating the slope, soil, drainage, purpose of the wall, and nearby structures. We also consider conditions above and below the proposed wall, including driveways, patios, buildings, and other improvements that may affect the design.Once the site has been evaluated, we select an appropriate wall system and plan the construction requirements. Depending on the project, installation includes preparing and compacting a stable base, setting the wall to the proper alignment and elevation, installing drainage aggregate and water-management components, adding geogrid or other reinforcement where required, and correctly placing and compacting backfill.
Much of this work is hidden behind and beneath the finished wall, but it is critical to long-term performance. Poor drainage, inadequate base preparation, or improperly compacted backfill can increase pressure behind a wall and contribute to movement or failure.
Built for North Atlanta Conditions
North Atlanta's red clay, rolling terrain, and periods of heavy rainfall make water management particularly important in retaining wall construction. Clay-rich soil can hold moisture, and runoff moving down a slope can place additional pressure on a wall if water is not properly managed.A retaining wall therefore needs to manage both the grade and the water moving through the surrounding soil. Proper drainage and construction help reduce hydrostatic pressure behind the wall and limit the movement that can occur as clay soils become wet and dry.
On steep properties, retaining walls can also reshape difficult terrain rather than simply stabilize it. Terracing can break a hillside into more manageable, usable levels while creating safer transitions between elevations.
Retaining Walls as Part of the Landscape
Retaining walls can be designed to do more than manage a change in grade. Steps can provide access between different elevations, while built-in planters, seating, and landscape lighting can make the wall part of a patio, garden, or outdoor living area. By planning these features together, Miller Landscape can integrate the retaining wall with the surrounding hardscape and landscaping while addressing the property's structural and grading needs.Engineering & Permit Considerations
Smaller landscape walls may be relatively straightforward, while taller, load-bearing, or complex retaining walls may require engineering and/or local permits. Walls located near structures, driveways, property improvements, or significant slopes can also require additional consideration.Requirements vary according to the wall and local regulations. These factors should be identified during planning so any necessary engineering or permitting can be addressed before construction begins.
