Looking for an experienced structural engineer for retaining wall design in Melbourne? At Altez Engineering, we provide compliant and cost-effective retaining wall design solutions for residential, commercial and development projects across Victoria.
Retaining walls must be properly engineered to resist lateral earth pressures, surcharge loads and hydrostatic pressure. Many retaining wall failures we assess in Melbourne are caused by poor footing design and inadequate drainage provisions, which significantly increase lateral loads behind the wall. Our designs are prepared according to the Soil Report and relevant Australian Standards, including:
Drainage is a critical component of retaining wall performance. Without proper subsoil drainage, hydrostatic pressure can build up behind the wall, often leading to cracking, rotation, bulging or long term structural movement. We ensure appropriate drainage detailing, footing embedment and structural sizing to achieve a safe and durable outcome.
Altez Engineering has experience designing a wide range of retaining wall systems across Victoria, including:
In Victoria, bored pier and pile footings are commonly used for retaining walls where deeper founding conditions are required, particularly on reactive clay sites or sloping blocks. The footing system is designed based on soil classification and engineering parameters provided in the geotechnical report.
Every retaining wall project requires proper Footing Design according to Soil Report classification. Soil reactivity, bearing capacity, slope stability and groundwater conditions all influence the structural design. We assess sliding resistance, overturning stability, bearing pressure and global stability where required.
We understand project timelines are critical. Altez Engineering provides fast drawings and clear structural documentation suitable for council approval and building permit applications. Our AutoCAD drawings are issued in PDF format for easy coordination with your builder, surveyor and council.

Below are some examples of retaining wall failure. Some retaining walls exhibit clear signs of vertical separation together with visible cracking extending through the masonry units. The crack appears to extend the full height of the wall and is of measurable width, indicating differential movement between adjoining wall sections rather than superficial shrinkage cracking. The slight misalignment and gap suggest lateral displacement, which is commonly associated with inadequate resistance to retained soil pressures or hydrostatic build up behind the wall.
The observed leaning and separation are consistent with long term earth pressure acting on a wall that may lack sufficient footing capacity, structural reinforcement, or adequate drainage provisions. In the absence of proper subsoil drainage, hydrostatic pressure can significantly increase lateral loading, accelerating rotation and cracking. The condition does not appear to be merely cosmetic and may represent progressive structural movement. A detailed engineering assessment is recommended to determine footing adequacy, drainage performance, and overall stability in accordance with AS 4678 for earth retaining structures.
A well designed retaining wall should consider site conditions, nearby vegetation, drainage provisions, and appropriate footing design to ensure long term durability and serviceability.
