Measured before specified
Movement, decay, cracking, corrosion, water and nearby loads shape whether a local repair or complete replacement can address the underlying problem.
Start with the site
A leaning, bulging, cracked, corroded or decayed retaining wall creates two linked questions: what is changing now, and what scope would prevent the same conditions being rebuilt into the replacement? The visible defect may relate to posts, footing, reinforcement, timber decay, water pressure, soil loss, changed loads or several factors together. That cause cannot be established reliably from one photograph. A useful first brief records the whole alignment, both wall ends, retained levels, nearby fences or driveways, wet areas, access and any change over time. This service differs from new construction because safe removal, temporary ground management, concealed discoveries, disposal and reinstatement are central to the decision.
Three project decisions
Photograph the wall straight-on and along its length, then add close images of cracks, post rotation, corrosion, rot, open joints or lost soil. Mark where symptoms begin and end and whether they change after rain or with time.
A local repair may have value where the cause and affected components are genuinely limited. Broader movement, widespread decay, inaccessible drainage or an unsuitable original arrangement can make partial work difficult to separate from the remaining risk.
The scope should explain how retained ground is managed, where demolition material and soil go, what happens around fences or structures and when concealed footing, services or drainage are inspected before the new design is finalised.
Included in a useful brief
Failure diagnosis records symptoms and relevant site context for qualified assessment; it does not promise a cause from photographs alone.
Safe demolition planning addresses work sequence, temporary ground, adjacent property, access, service uncertainty, disposal and inspection hold points.
Replacement wall scoping coordinates the new structure, drainage, backfill, approvals, finishes and reinstatement with the cause-led findings.
A visible sequence
Capture the complete wall, dated defect photos, water behaviour and any recent change in the loads or ground around it.
Keep people away from visibly unstable work zones and seek appropriate professional advice where immediate safety is uncertain.
Review repair limits, demolition sequence, concealed unknowns, drainage path and professional design or approval needs.
Compare replacement proposals on the assessed cause, full structure, water control, access, exclusions and reinstatement.
Decision guidance
Show post movement, sleeper condition, ground above and outlet location. A straight replacement line may conflict with old concrete, services or the boundary and needs fresh set-out.
Map crack direction, width changes, rotation and moisture. Surface patching can hide evidence, so obtain assessment before selecting a cosmetic finish as the remedy.
Inspect the broader run and each tier where safe. Local sleeper decay can exist beside post movement or persistent wetness that changes the sensible repair limit.
Risk boundaries
Movement should be taken seriously, but its cause and urgency cannot be determined from a suburb and one symptom. Keep clear of an unstable-looking wall and arrange property-specific professional assessment.
Replacing the visible material without revisiting load, footing, drainage, outlet and access can reproduce the original weakness. The new written scope should show what changes and why.
Why use this process
Condition evidence comes before the replacement material decision.
Temporary ground, disposal and concealed inspection are treated as real work.
Local work is compared with the condition and water path of the complete wall.
