Retaining Wall Perth: Retaining Wall Repairs & Replacement

A failing retaining wall rarely fails for one dramatic reason - it's usually a slow drainage problem that finally shows up as leaning, bulging or a cracked face. The first job on a repair enquiry is diagnosis: is this a drainage fix behind an otherwise sound wall, a partial rebuild of a failed section, or does the whole wall need replacing. Perth's sandy, winter-wet ground makes drainage failure the most common cause we see, which is good news in one sense - it's often fixable without a full rebuild.

What's included

Failure assessment

On-site inspection of the wall, drainage condition, footing and the extent of movement or damage.

Drainage remediation

Where poor or failed drainage is the root cause, retrofitting ag-drain and free-draining backfill behind the affected section.

Partial and full replacement

Rebuilding a failed section, or the whole wall where the structure is beyond repair.

Repair cost varies enormously by failure mode - a drainage retrofit behind a sound wall costs far less than a partial or full rebuild. An on-site assessment is the only reliable way to scope it.

How the process works

  1. 1

    Inspect and diagnose

    Identify whether the cause is drainage, footing movement, material failure (e.g. rotted sleepers) or a combination.

  2. 2

    Scope the fix

    Repair vs partial rebuild vs full replacement, based on what the inspection finds.

  3. 3

    Approval check

    Replacement work is generally assessed the same way as a new wall under current rules, even where the original predates them - confirmed before work starts.

  4. 4

    Carry out the repair

    Drainage remediation and/or rebuild, with the same drainage standard as a new wall.

Why get retaining wall repairs & replacement help through us

Diagnosis before a quote

The cause of the failure is identified before a repair scope is priced, not assumed.

Fixes the cause, not just the symptom

A leaning wall with a drainage problem gets the drainage fixed, not just the lean pushed back.

Straight talk on repair vs replace

Where a section is beyond repair, that's said plainly rather than patching something that will fail again.

Retaining Wall Repairs & Replacement - Frequently Asked Questions

What are the warning signs a retaining wall is failing?
Common signs include visible leaning or bulging, cracking or stepped cracks in block or rendered walls, rotting or bowed timber sleepers, gaps opening at the base, and water pooling or seeping through the wall face rather than draining away.
Does a retaining wall need to be engineered if it supports a pool?
Where a retaining wall forms part of a pool barrier or carries a surcharge from a pool structure, it is more likely to need building approval and an engineer's design regardless of height, because of the surcharge and safety-barrier requirements involved.
Can I build a retaining wall myself in WA?
A wall that retains no more than 0.5 metres, is not tied to other building work, and does not affect adjoining land or a boundary can be exempt from needing a building permit. Anything beyond that generally needs council approval and, depending on height and load, an engineer's design. Confirm your specific wall against your council's retaining wall information sheet first.
