Sample Gravity Wall Calculations
Analyze a gravity wall with the following site conditions:
   

Reinforced Soil Walls
When retaining wall heights exceed those listed in the gravity wall chart, geogrid can be added to provide a stable retaining wall condition
Geogrids are flexible, synthetic meshes which are manufactured specifically for slope stabilization and earth retention.

Working with Geogrid
Retaining wall block can be used to construct walls that retain, or prevent the movement of the soil. The maximum height these walls can be built without the use of reinforcement is dependent on these primary conditions.
How Does Geogrid Work?   Allan Block Video Logo
   

No-Fines Concrete Backfill
Use of AB No-Fines Concrete Backfill has increased our ability to install reinforced retaining walls in locations where typical construction would not be possible because of property line constraints or limited excavation options.

Working with Soil
The soils used below and behind the wall are a critical part of the total wall structure.
A reinforced retaining wall is a structure containing three basic building materials - the block facing, the synthetic geogrid reinforcing materials, and the infill materials surrounding the geogrid layers
Soils and Soil Selection
Typical Friction Angle and Soil Unit Weights Chart
   

Retaining Wall Compaction
Proper placement and compaction of the infill soils are critical.
The most important step in getting proper compaction.
The consolidation zone runs from the back of the block back 3 ft (0.9 m) into the infill soil.
   

Water Management
The design and performance of most retaining walls are based on keeping the reinforced zone relatively dry.
Things to consider in our design:
Grading, Ground Water, and Concentrated Water Sources.

Building Terraces
It is often more aesthetically pleasing to replace one large retaining wall with two or more smaller terraced walls. Terraced walls can act as surcharges and may create global instability, therefore reinforcement may be necessary.
   

Building Water Applications
Retaining walls constructed in conditions where there is moving water (streams), standing water with wave action (lakes), or retention ponds are considered water applications.
Water applications must be evaluated and designed to fit the unique characteristics of the site. Consult with a local qualified engineer for design assistance.
   

Adding Fences, Railings and Gates
There are several options for installing fences and guide rails on top of an Allan Block retaining wall. The structure and wind loads of the materials used will determine the placement of the fence relative to the retaining wall and if additional reinforcement is required. Refer to the approved plans for construction details.

Lighting for Retaining Walls
Lighting brings new possibilities to any landscape. Add a dramatic look with ground mounted lighting or illuminate stairways and pathways with recessed lighting. Allan Block walls with decorative lighting fixtures provide not only a distinctive design, but adds safety and security to the landscape.

How to Install the Base Course Blocks for AB Retaining Walls

Achieving a level and properly aligned base course is fundamental to the structural integrity and longevity of retaining walls. Employing precise layout techniques—such as utilizing string lines, laser levels, and meticulous block alignment—facilitates the establishment of an optimal foundation. It's important to recognize that any discrepancies in the base course can become increasingly pronounced in subsequent courses, potentially compromising the wall's performance. Therefore, meticulous installation of the base course is essential for the success of any retaining wall project.?

How to Enter your Elevation View in the AB Estimating Tool

Accurate material estimation is essential for effective project planning and execution. This video provides a detailed walkthrough of how to input the Elevation View into the AB Estimating Tool, enabling design professionals to generate precise quantities for block, geogrid, and other wall components. It also defines key terms related to wall profiles to ensure clarity in design interpretation. By following the step-by-step process, you can produce reliable estimates that support budgeting, material coordination, and specification compliance. For full access to this resource and other design tools, visit allanblock.com.

Allan Block SRW Design Software - Product Selection in AB Walls

The Product Selection Screen in AB Walls allows design professionals to configure their project based on the local Allan Block producer, ensuring accurate block specifications and availability. This step is essential for aligning design intent with real-world supply and constructability. The software also walks you through geogrid selection, offering the ability to choose from available options or fully customize reinforcement to meet project requirements. Setting up these details correctly at the start of the design process is critical for producing accurate plans, optimizing performance, and ensuring a smooth transition from design to construction.
