Building a retaining wall involves planning, approvals, site prep, construction, and drainage. While small walls can be DIY, most Perth walls benefit from professional installation.
Key Steps
- Choose your wall type and design
- Get engineering plans (required for walls over 0.5m in WA)
- Apply for council approval
- Prepare the site and excavate foundations
- Install drainage, build the wall, backfill
