Retaining-wall engineering for new, existing and boundary structures.
Elite provides site-specific structural and civil engineering for retaining walls, boundary structures and associated fence support. Design and assessment consider retained height, ground conditions, surcharge loads, drainage, nearby structures, boundaries, services, access and construction constraints.
Design, assessment and rectification of retaining structures.
New retaining walls
Concrete sleeper, reinforced concrete, block, gravity, segmental and recycled concrete block retaining-wall systems.
Boundary walls and fence support
Retaining structures supporting fences or barriers, including wall-and-fence loading, boundary position, construction access and nearby works.
Existing retaining-wall assessment
Assessment of leaning, cracked, displaced or deteriorated retaining walls, with rectification or replacement design where supported by the available evidence.
Documentation and inspections
Structural and civil calculations, drawings, drainage coordination and Form 15 design certification are provided where applicable to the agreed scope. Construction-stage aspect inspections may be undertaken where included in a separate agreed inspection scope.
Site conditions and loading govern the retaining-wall design.
Ground and retained geometry
Retained height, wall geometry, soil properties, groundwater, sloping ground and adjoining surface levels.
Surcharge and nearby structures
Driveways, vehicles, buildings, pools, stored materials, nearby footings, other retaining walls, fences and applicable wind loading.
Drainage and durability
Drainage aggregate, filter material, ag-line, lawful discharge, corrosion exposure and long-term durability.
Boundaries, infrastructure and construction
Boundary position, council assets, utility infrastructure, available construction access, staged construction and temporary stability.
Information required for a coordinated retaining-wall design.
Send the available site, level, wall and surrounding-property information. Elite will identify whether survey, geotechnical, certifier or other technical input is required for the agreed engineering scope.
Site and levels
Feature and level survey, boundary information, proposed wall alignment, retained heights and existing and proposed surface levels.
Wall and fence
Proposed wall system, fence type and height, and photographs showing the site, wall alignment and nearby features.
Surrounding constraints
Nearby buildings, driveways, pools, slopes, other retaining walls, council assets and available service information.
Supporting records
Geotechnical information where available or required, together with relevant certifier or council correspondence.
Assessment of existing retaining walls.
For an existing wall, a site inspection can document visible condition and movement, but concealed footing dimensions, post embedment, reinforcement and drainage may require targeted investigation before structural adequacy or a rectification design can be established.
Further investigation where required
- Level survey or monitoring
- Selected excavation to establish footing or post geometry
- Opening drainage zones
- Material testing
- Structural analysis
- Repair, anchoring or buttressing design
- Replacement retaining-wall design
- Assessment for a retrospective approval pathway where required
Engineering input for the building-approval pathway.
The building certifier determines the building-approval pathway. Boundary setbacks, combined wall-and-fence height, nearby structures and council infrastructure can affect the required documents and referrals.
Elite provides structural and civil engineering for the agreed scope but does not replace the private building certifier, cadastral surveyor, geotechnical engineer or relevant authority.
Contact Elite about your retaining-wall project.
Send the project location, photographs, approximate retained heights, proposed wall type, fence information where applicable, and any available survey, geotechnical or council information. Elite will review the information and advise the appropriate engineering scope.
