The natural beauty of stone enhances any landscape. Our stone masons take enormous pride in crafting every piece they lay into place. Private Landscape can meticulously construct patios, staircases, mailboxes, pool coping, stepping stone pathways, driveways, terraces, decorative borders/edging, and sidewalks from a variety of masonry materials to bring elements of style into your property.
Stepping Stone Pathways
Most stepping stone pathways are constructed to a width of about 3 feet. The stone is Crab Orchard, which has a natural earth tone color of brown, tan and reddish brown veins. Each stepper is irregularly shaped with a nominal dimension of 20-24 inches. The area is excavated for each stepper to be carefully aligned and leveled in place. Each of these pathway stones are set flush to the ground surface by excavating for each stone. Often, River Slick stones are set between each stepper and on each side. The River Slicks have a nominal dimension of 4-6 inches, and help prevent erosion from occurring within the stepping stone pathway. Also, they help define the pathway. The result will be a uniform, durable, safe step system, requiring no maintenance (other than blowing off any tree debris).
Crab Orchard Flagstone or Fieldstone patios are excavated and the sub grade compacted using a mechanical tamp. Four inches of crusher run base material is placed and compacted using a mechanical tamp. A one inch layer of leveling sand is installed. This stone typically has a nominal thickness in the range of 2-2½ inches, and plan dimensions in the range of at least two 2-3 square feet. Each stone is carefully placed and fitted so that mortar joints are relatively small and uniform. The patio is designed to properly shed water and eliminate any standing water. Utilizing thicker stone coupled with meticulous construction will result in a patio that will be extraordinarily durable and with outstanding fit and finish.
Stone Stepper Staircases
Crab Orchard stepper staircases create ease of passage from point A to point B, in an attractive and stylish manner. The staircases include a series of Crab Orchard stone step treads. The Crab Orchard stone, like slate, is a sedimentary rock. The important difference is that the Crab Orchard material has a higher sand content than slate, which means better slip resistance when wet. The Crab Orchard stone materials will have earth tones tending toward brown in color. The step treads are a cut stone with a width of 24 inches and a length of 24 inches with a thickness approximately 5½ inches. This will result in uniform stone steps each with nominal tread width in the range of 16 inches and a tread or step height of approximately 5½ inches. The area for each stepping stone is excavated in order that each stepping stone is flush with the ground surface. The weight of each stepping stone precludes the need for mortar, and creates a simple and natural staircase.
Private Landscape offers advanced knowledge and skill in installing and/or repairing retaining walls. Retaining walls can be chosen for aesthetic landscape appeal, to support various structures, or as a necessity in preventing landscape erosion or collapse. We have a Senior Geotechnical Engineer on staff who understands the technical requirements for retaining wall effectiveness including appropriate foundation work, prevention of hydrostatic pressures, installation of geogrid materials and the best qualifying wall components to meet your needs. Most Georgia counties require a fall-safe wall construction. A powder-coated aluminum fence will be installed at the top of any wall that is greater than 3 feet in height, as required by county code. This will prevent the hazard of falling from the top of the wall.
Following are select installation specifics for different types of walls:
A foundation for the new wall is constructed by excavating to a depth of approximately 8 inches below the ground surface. This excavation is typically 18 inches in width for the full length of the wall. The first course of modular block is carefully placed and interlocked with the next layer using fiberglass pins inserted into the openings in each block. The wall is constructed with a setback of 1¼ inches per course of block. As the wall progresses upward, #56 stone is backfilled into each block cell for a depth of 18 inches from the face of the wall. Capstones are placed at the top of the wall for a finished appearance. A fabric is installed between the stone backfill and the soil. This fabric membrane minimizes the potential for soil particles to wash or “bleed” through the completed wall system. This “bleeding” results in discoloration of the wall over time. The top of the wall is capped with four-inch solid block, adhered to the wall blocks with special adhesive.
A concrete footing typically extends 6 inches into the ground and is contiguously reinforced with #4 rebar. This footing is approximately 10 inches in thickness. The wall is constructed using masonry block that is secured to the foundation by means of vertical reinforcing bars spaced at regular intervals. These bars are set in the foundation and extend through the hollow block. The block cavities, where steel reinforcing exists, are filled with concrete. Tennessee Thick Stack and Tennessee Thin Stack stones materials with a nominal thickness in the range of 2 inches are blind-mortared onto the masonry block. This technique results in a stacked stone appearance with the strength of a reinforced concrete wall. The cap of the wall has Tennessee Fieldstone materials with a width of approximately 12 inches. A drainage system is installed at the back side of the retaining wall and weep holes at the base of the wall in order to eliminate hydrostatic pressures. Finally, the wall is capped with Crab Orchard Flagstones.
A six inch wide foundation is created and excavated to a depth of six inches below grade. A four-inch thick layer of crusher run is installed and thoroughly compacted using a mechanical tamp. Any soft zones are excavated and replaced with compacted crusher run. A concrete wall will extend into the ground for a minimum depth of 6 inches and will be built on a properly compacted soil with a sand/gravel leveling base. The Crab Orchard stack stone will adhere to the new concrete foundation wall. It will extend outward in approximately 6 inches from the face of the foundation wall. Each stone is carefully fitted and blind mortared in place. Each Crab Orchard Stone is mortared to the next in such a manner that the mortar is minimally visible leaving a stack stone look with the strength and durability of a mortar wall.
