Levels & loads
Natural ground, retained height and loads from driveways, structures or sloping land influence the design.

Concrete sleeper retaining walls from Bundoora across Melbourne
Retaining walls planned around soil, levels, drainage, access and the fencing that often needs to sit above them.
Complete site thinking
The wall, drainage and fence must work together.
A retaining wall is a structural site element, not simply stacked sleepers. The scope must account for the retained height, soil, surcharge loads, drainage, nearby structures, title boundaries, underground services and safe excavation access.
RJL can coordinate excavation, concrete sleeper and steel-post systems, drainage and the fence above as one practical package. Engineering and permit pathways are confirmed where the property and scope require them.
- Concrete sleeper retaining walls with galvanised steel posts
- Excavation, footing preparation, drainage aggregate and agricultural pipe
- Integrated Colorbond, timber, aluminium or steel fencing above
- Engineering and approval coordination where included in the scope
- Site cleanup and practical handover
Concept image: The hero visual illustrates the material system only. Every retaining wall must be designed and priced for its actual site conditions.
Retaining-wall scope
What the site assessment needs to resolve.
Soil & footings
Ground conditions and engineered requirements determine post size, depth, spacing and concrete footings.
Drainage
Aggregate, filter fabric, agricultural pipe and a legal discharge path reduce pressure behind the wall.
Boundaries
Title lines, adjoining property protection and excavation access must be confirmed before work begins.
Permits
Height is only one factor. Location, structures, easements and local planning controls can change the approval pathway.
Fence above
Posts, fixings, wind load and the final boundary height are coordinated with the wall—not improvised later.
Approvals
Check the property, not a generic rule.
Victorian permit requirements can vary with height, boundaries, adjacent buildings, easements, loads and local planning controls. Your council and building surveyor should confirm what applies before construction.

Retaining-wall FAQ
Questions before excavation starts.
Does RJL build concrete sleeper retaining walls in Bundoora?
Yes. Suitable residential projects can include excavation, concrete sleepers, galvanised steel posts, drainage and the fence above, subject to site conditions, access and approval requirements.
Can a fence be installed on top of a retaining wall?
Often yes, but the wall, post support, wind load, drainage and final boundary height must be designed and coordinated together rather than added independently.
When does a retaining wall need a permit?
The answer depends on height, boundary location, support of neighbouring land, nearby structures, easements and local controls. The relevant council and building surveyor should confirm the property-specific requirement.
What information helps with a retaining-wall quote?
Send the address, approximate wall length and retained height, clear photos, access width, the fence required above and any plans, engineering, title or known service information.
