Precast Concrete Retaining Wall Systems

AFTEC is among the notable and distinguished service companies for retaining walls in North Carolina!

The retaining walls manufactured by the AFTEC are made to endure the parallel and oblique pressures of Earth. These retaining walls by AFTEC are fabricated in multiple unique designs with captivating textures and finishes.


What are Retaining Walls?

Made up of retaining wall blocks which in turn are made up of various substances and materials, Landscape retaining walls serve a number of important functions. It goes without saying that they are meant to render support to the elevated walls and inclined soils against the upright pressures and force-pull of Earth.

Moreover, these precast retaining walls are erected to profer ultimate support to the wall structure of the building and shield them from corrosion, erosion, and landscaping.

AFTEC has a glimmering portfolio of manufacturing and constructing multiple kinds of retaining walls, which include, gravity, sheet-piled, and cantilever employing a wide-range of texture designs, polishes, and finishes to add to the individuality and uniqueness of the retaining walls.

Concrete Retaining Wall Blocks

AFTEC prides over the fact that it manufactures and constructs durable retaining walls utilizing intricately engineered concrete blocks on visible facades, and finishing the job with modern and unique architectural designs.

Large retaining wall blocks are used to hold and withstand small to medium sized walls (up to around 12 ft.) within the multiple levels of Earth. Precast barriers and fence are installed on the top of the walls and soil-grades for the added security, wherever it is needed. We, at AFTEC, are pleased to tell you that we extend professional and expert retaining wall installation services in North Carolina -Charlotte, Raleigh, Greensboro, Wilmington, and the places around.


Types of Retaining Walls

AFTEC practices constructing multiple types of retaining walls as per the individual client demands and specifications. We excel at building large precast concrete retaining wall blocks for added support to the small to medium-sized walls as told earlier. These wall sizes may reach up to 12 ft.

Below-mentioned as some of the commonly manufactured retaining wall types:

To add to the durability and reliability of the Gravity retaining walls, they are built using rigid-footing ways and methods. Gravity retaining walls are designed and constructed using large concrete blocks. The walls, then, yield support from the weight of concrete blocks to resist the oblique pressure of the gravitational forces.

We, at AFTEC, are quite gratified to announce that we specialize in designing, engineering, constructing, and establishing retaining walls as per the demands, requirements, and specifications of our clients. Numerous aesthetic finishes, designs and textures further add to the versatility of the retaining walls. Walls constructed by us are enduring and can easily withstand substantial gravitational force pressure, without exhibiting any symptoms of weathering or erosion.


Masonry units such as CMU block walls are typically used to build and erect retaining walls. Made up of kiln-fired brick and mortar, they are ordinarily 8” x4” x2.25” in size. They are frequently consolidated with steel for added reliability, durability and an increased lifespan.

Sheet Piled

Various materials such as plastic planks, fiberglass, wooden planks, vinyl, and steel, are used to construct Sheet Piled retaining walls. To improve the vitality and durability the sheet piled walls must be hammered at least two-third the slope of the wall into the soil.


One of the most prevalent and top-consumer choice these days are the Cantilever retaining walls. These types of walls are cautiously engineered and manufactured using concrete and masonry consolidated with steel to form durable cantilever blocks.

The cantilever is known to transmute lateral pressures of gravitational forces in an upright way to negate its influence. The Cantilever wall blocks are acknowledged to render the sound architectural base to dependably withstand large soil slopes.

Precast Retaining Wall Materials

AFTEC industrial and commercial retaining walls consist of precast concrete panels and columns designed and engineered to withstand the lateral pressures of the earth to be retained. These walls are available with architectural finishes such as stone, brick, block, stucco or custom architectural designs on the visible side of the wall.

  • Concrete: Aggregate, cement powder and water designed for the engineered mix desired. Steel reinforcement and concrete are the ultimate materials for building retaining walls.
  • Concrete Blocks: Small rock aggregate, cement powder and water formed into a hollow block. The concrete blocks are then stacked on continuous concrete footings using grouted cells and reinforcing for structural strength. Labor intensive.
  • Cinder Blocks: Volcanic aggregate, cement powder and water formed into a hollow block. The cinder blocks are then stacked on continuous concrete footings using grouted cells and reinforcing for structural strength. Labor intensive.
  • Stone: Stone is sometimes used for retaining walls in areas where it is plentiful by slant stacking, using the specific gravity of the stone to retain earth.
  • Brick: When used, brick is a fascia on retaining walls for appearance. Brick does
    not have structural integrity for retaining capabilities.
  • Stucco: Stucco is also used for an fascia appearance on retaining walls.
  • Wood: Wood timbers or rail road ties are sometimes used for retaining walls, but unless properly treated, wood deteriorates.
  • Steel: Steel is used in all steel reinforced concrete retaining walls for structural strength.

Building a Retaining Walls System in North Carolina

Design Process

The foremost step that goes into building a retaining wall system is design engineering. The design has to get approved first before initiating the production process. Our molding workshops word hard to assemble the design-specific concrete retaining wall blocks to construct the retaining walls system. The production process is generally carried on employing the Forming Equipment by one of the AFTEC producers that operate near the jobsite.

Retaining Walls System Installation

The installation process of a retaining walls system begins with the digging and excavation of the Caisson foundations. The Caisson foundations are then flooded to the precise height with the structural support and columns, installed into the foundations. After lying down the Caisson foundation, the wall blocks or panels are delivered and installed.

Cost Determinants

The cost of designing, producing and installing a retaining wall system for a project is determined by many factors that are mentioned below

  • Project Location
  • Retaining Height
  • Wall Length
  • Soil Conditions
  • Lateral Pressure and Loads
  • Water Drainage
  • Required Backfill
  • Architectural Finish Type
  • Labor Conditions
  • Right Equipment Availability
  • Owner/Contractor
  • Requirements for Jobsite
  • Underlying Obstructions,
  • Obstacles, Utilities, etc.
  • Overhead Bridges,
  • Obstacles, Barriers,
  • Utilities, etc.


Benefits of Precast Concrete Retaining Walls

Besides providing the most reliable support against the vertical and upright pressures of the gravitational pull, the retaining walls also have the following additional benefits:

  • Appealing Impression: AFTEC designs, engineers and manufactures the retaining walls as per the requirements of the clients and add multiple textures, designs and finishes to increase the overall aesthetic appeal.
  • Erosion Control: One of the main reason for the erosion is the lack of proper wall-support. Other than this it is also caused by the imbalanced construction techniques. Concrete retaining walls provide the ultimate support and tackle efficiently the erosion phenomenon.
  • Flood Prevention: Homeowners residing near small or big water bodies can relate to the fact that there are occasional floods. Installing retaining walls provides you with a shield and can protect you against floods.
  • Cost-Effective: AFTEC uses some of the most long-lasting and enduring materials to construct and engineer walls, one such is cantilevered concrete. High grade cantilevered concrete is used to increase the reliability and durability of the retaining walls. Hence, the overall cost is reduced making the project cost-efficient.

Service Areas: Charlotte, Raleigh, Wilmington, Greensboro, Asheville, Durham, Fayetteville, Chapel Hill, Cary, Winston-Salem, High Point, and in all other cities of North Carolina.
