Austin Block Company is one of the leaders in building retaining walls in the Southeastern United States. Our clients consist of commercial general contractors, residential developers, and homeowners. As a design-build contractor, Austin Block Company provides retaining walls at the right price and scope to its clients.

Retaining walls built with natural stone will last for generations. A beautiful and durable limestone retaining wall will last for decades, if not centuries, to come. The longevity of these walls is attributed to the superior quality of our limestone blocks.

Austin Block Co. stands behind our designing and build of any type of stone or block project. We have engineered drawings if needed along with Architectural 3D renderings upon request. We have a vast majority of our projects that are new construction, but we offer rebuilding and repairing walls as well!

These beautiful, durable blocks are quarried from a high grade limestone quarry located just outside of Austin Texas, which means that you are sure to get nothing but the highest quality limestone for your project.

Retaining walls are important structures that support an uneven landscape. They are often used to prevent soil erosion and make the most of your yard. If you need to hold back soil on one side while letting water drain on the other side, then a retaining wall is perfect for you.

We have the perfect natural stone retaining wall to complement your outdoor space. With a variety of styles and colors, we are sure to have the right solution for any size project. Our natural stone block walls are designed with curves, angles, slopes and steps to suit any landscape.

A well constructed retaining wall will add character and value to your property and can make all the difference in your outdoor living space. Austin Block Co offers natural stone retaining walls that are long lasting, durable, and beautiful.

Block Wall

 A block wall is our most popular, and most often recommended type of retaining wall. The limestone blocks can be installed in a number of ways, depending on your project’s specific needs and limitations. Block walls are perfect for any retaining wall two feet or higher. The limestone is available in multiple different sizes and colors to give your property an elegant look with timeless protection. Block walls can also be assembled with concrete blocks for a more cost-effective design.

Mortared Stone Wall

 Our mortared mixed-stone walls are an excellent choice for smaller walls and garden walls, as well as anyone who is going after a certain aesthetic. Typically, we use chopped limestone or flagstone to complete these walls. The stone comes in a variety of colors and shapes. We use a white or grey masonry mortar to fill the gaps between the stones, because of this, it is important to add a drain pipe behind the wall to allow for water passage.

Dry Stack Wall

 A dry stack wall is a type of retaining wall that does not require mortar, geogrid, pinning or reinforcement. Instead, the stones are placed onto one another directly. Gravel and smaller rocks are used to fill in gaps between the stones, but excess space that is left allows for water to drain out the face of the wall naturally. This type of wall design is perfect for smaller accent walls, garden walls, or to build planters, however due to their lack of reinforcement we do not recommend this wall design for any walls higher than 3 ft, or for any wall serving a structural purpose.

Segmantal Retaining Wall

Segmental retaining walls are the latest innovation in modular retaining wall design. These pre-cast concrete blocks feature a rough split-face and can be easily set in place. The set-back guide line allows for precise placement on site, while the hollow blocks are light and easy to handle. This makes segmental retaining walls the ideal DIY option for your next retaining wall project.

  • Earth-In-Footing
  • Drainage Rock & Fabric
  • Backfill
  • Concrete Footing
  • Block Pinning & Geo-grid

Earth-In Footing

All unusable spoils should be removed. Once all of the unsuitable materials have been removed, the bottom of the footing should be sufficiently compacted. Once the footing subgrade has been compacted, a select fill should be installed between 6″- 8″ lifts. The depth of your base layer is influenced by the soil type and application. The base layer should be leveled and compacted firmly. This should help safeguard against shifting and/or settling.

Drainage Rock & Fabric

To help protect against drainage issues, we suggest using washed gravel behind our block walls. Once the gravel has been installed, we will install our heavy-duty Geo-fabric to help keep fill material separate from the gravel.

Backfill

After all the blocks are stacked and the filter rocks and fabric are in place, there is back fill dirt that is filled in on top of the filter rocks and fabric and behind the wall. In some cases there are drains and piping place within and behind the wall for drainage purposes.

Concrete Footing

Concrete footing would usually be used where soil conditions are poor or when exceeding the maximum unreinforced wall heights with an engineered design. First, we excavate a 6″- 8″ deep trench to lay the foundation in. Once the soil has been cleared out, we install the stakes and planks to pour the concrete, as well as the rebar to support our footing. Lastly, we pour the concrete, allow it to dry, and begin constructing the wall.

Block Pinning & Geo-grid

Our Block Pinning and Geo-Grid option, gives your retaining wall extra durability and stability. Rebar pins are installed, linking the blocks together vertically, Geo-Grid material is then added between each layer to anchor the blocks laterally to the fill material. This helps to prevent shifting, sliding, and/or settling.
