HOW THE SYSTEM WORKS
How core-filled block retaining walls are constructed.
- Concrete masonry blocks are laid in courses to form the wall.
- Reinforcing steel is installed in accordance with the engineering design.
- The block cores are filled with concrete or specified grout.
- The wall is supported by an appropriately designed footing.
- Backfill and drainage are incorporated as required by the project design.
APPLICATIONS
Applications for core-filled block walls.
- Civil infrastructure and roadworks
- Commercial and industrial developments
- Subdivision and land development
- Site level changes and access areas
- Selected boundary and hardstand retaining applications
Final suitability depends on wall height, ground conditions, loading, available space and engineering requirements.

FOOTINGS & FOUNDATIONS
Engineering, footings and foundations.
A properly designed footing is essential to the strength, stability and long-term performance of a core-filled block retaining wall. The footing provides the foundation for the reinforced blockwork and must be designed to suit the wall height, ground conditions, soil bearing capacity and imposed loads.
Urbanscapes coordinates footing construction as part of the retaining wall installation, with excavation, reinforcement and concrete placement completed in accordance with the project-specific engineering design.
Key footing considerations
- Excavation and preparation — The foundation trench is prepared to the dimensions and founding conditions specified by the engineer.
- Steel reinforcement — Reinforcement is positioned in accordance with the structural drawings to provide the required footing capacity.
- Concrete placement — Concrete is placed to the specified dimensions and strength requirements.
- Ground conditions — Footing design accounts for site soil conditions, bearing capacity and any relevant groundwater or geotechnical requirements.
- Structural integration — The footing and reinforced block wall are designed to work together to resist the loads imposed on the retaining structure.
Footing dimensions, reinforcement, concrete specifications and founding depth are determined by the project engineer. These requirements should be confirmed before construction begins.

PROJECT PLANNING
Engineering and construction considerations.
Core-filled block retaining walls are constructed using reinforced concrete masonry, with the structural design determining the wall configuration, reinforcement, concrete-filled cores and footing requirements.
Several factors need to be considered when planning a reinforced block retaining wall:
Wall height and retained ground
The wall height and the amount of ground being retained influence the structural design. Changes in ground level, nearby structures and available construction space must be considered during project planning.
Soil conditions and site loads
Ground conditions, soil bearing capacity, groundwater and any additional loads near the retaining wall need to be assessed. These factors help determine the required footing dimensions, reinforcement and structural detailing.
Reinforcement and concrete filling
Steel reinforcement and concrete or specified grout are incorporated into the blockwork in accordance with the engineering documentation. The reinforcement arrangement and filling requirements vary depending on the wall design.
Drainage and backfill
Drainage and backfill details are important considerations for retaining wall performance. The appropriate drainage materials, water management provisions and backfill requirements should be established as part of the project design.
Urbanscapes coordinates retaining wall construction in accordance with the applicable project engineering and site requirements. Final wall details, material specifications and construction methods are confirmed for each project.

INSTALLATION PROCESS
Core-filled block retaining wall installation process.
Our core-filled block retaining wall construction process follows the project engineering and site requirements to ensure each stage is coordinated and completed correctly.
STAGE 01
Site preparation and set-out.
The construction area is prepared, and the retaining wall alignment, levels and footing locations are established in accordance with the approved drawings. Excavation is carried out to the required dimensions and depths, with site conditions assessed before footing construction begins.
STAGE 02
Footing construction.
Footings are constructed to the specified dimensions, reinforcement requirements and concrete specifications. The footing provides the structural foundation for the retaining wall and is completed in accordance with the project engineering.
STAGE 03
Reinforced blockwork construction.
Concrete blocks are laid in the specified pattern and alignment, with reinforcement installed in accordance with the structural design. Wall height, alignment and reinforcement placement are checked as construction progresses.
STAGE 04
Concrete core filling.
The block cores are filled with concrete in accordance with the engineering specifications. This creates a reinforced concrete retaining wall structure designed to resist the loads and ground pressures specified for the project.
STAGE 05
Drainage and backfill.
Drainage materials and systems are installed in accordance with the approved design to manage water behind the retaining wall. Backfilling is undertaken using specified materials and appropriate placement and compaction methods to minimise excessive pressure on the completed wall.
STAGE 06
Completion and project handover.
The completed retaining wall is reviewed against the project requirements, with final works and any required documentation coordinated with the project team.
FAQS
Frequently asked questions.
What is a core-filled block retaining wall?
A core-filled block retaining wall is constructed using concrete masonry blocks with steel reinforcement and concrete or specified grout filling the block cores. The reinforced masonry wall and its footing are designed to resist the loads imposed by the retained ground and site conditions.
What are core-filled block retaining walls used for?
Core-filled block retaining walls are used in civil infrastructure, commercial and industrial developments, subdivisions and other projects where changes in ground level need to be managed. Suitability depends on the wall design, ground conditions, loading and available space.
Does Urbanscapes supply and install core-filled block retaining walls?
Yes. Urbanscapes offers core-filled block retaining wall construction, as well as supply-only options for contractors and installers undertaking their own construction. The scope of work is agreed for each project.
Do core-filled block retaining walls require engineering?
Yes. Structural engineering is required to establish the appropriate wall configuration, reinforcement, footing dimensions and other construction requirements. These details depend on the wall height, soil conditions, loading and project specifications.
What determines the footing requirements for a core-filled block retaining wall?
Footing requirements depend on factors such as wall height, soil bearing capacity, ground conditions, groundwater and loads acting on the wall. The project engineer determines the footing dimensions, reinforcement, concrete specifications and founding depth.
Can core-filled block retaining walls be used for commercial and industrial developments?
They can be suitable for selected commercial and industrial retaining applications, subject to the engineering design, site conditions and project requirements. Urbanscapes can discuss the proposed application and construction scope with your project team.
