Retaining Walls Direct delivers concrete sleepers, galvanised steel H-beam and C-channel posts, drainage kits and retaining wall accessories to Bundaberg, Bargara, Gin Gin, Childers and surrounding areas across the Wide Bay–Burnett region. We supply residential homeowners, landscapers, builders and civil contractors throughout the Bundaberg LGA.
Bundaberg's subtropical climate brings significant seasonal rainfall — typically 1,000–1,200mm per year concentrated in the November-to-April wet season. Flooding and waterlogging in low-lying cane and farming country surrounds the city. Retaining walls in this region must be built with drainage designed to handle saturation events. Hydrostatic pressure during flood periods is a primary failure cause.
Important: Council approval and engineering requirements vary by wall height, location and soil type. Always check with Bundaberg Regional Council or engage an engineer before commencing. Retaining Walls Direct supplies materials only.

Bundaberg's coastal and riverine plains feature alluvial soils — often sandy or silty with high moisture-retention capacity. Inland areas carry heavier clay soils. Reactive clay soils in the region require post spacing of 1.5m maximum and additional drainage. The Burnett River floodplain creates localised saturation risks that must be accounted for in wall design.
Under the Queensland Building Act 1975, retaining walls over 1.0m require a building permit and QBCC-licensed contractor. Walls near boundaries or easements may require approval at lower heights. Contact Bundaberg Regional Council to confirm your requirements. QBCC: qbcc.qld.gov.au
Every retaining wall must include 20mm drainage aggregate for the full retained height, slotted ag-drain pipe at the base directed to a legal discharge point, geotextile fabric (min 140gsm) between backfill and drainage aggregate, and weep holes in the wall face at 1.8m centres. In flood-risk areas, drainage outlets must not be blocked by mulch or debris build-up. Browse drainage products →
Walls over 1.0m require a building permit from Bundaberg Regional Council under Queensland law. Walls near boundaries may need approval at any height. Always check with council for your specific property.
Yes — concrete sleepers are far more resistant to flood and moisture damage than timber sleepers. The key is correct drainage design so hydrostatic pressure does not build up behind the wall during flood events.
Standard 75mm × 200mm sleepers suit walls up to 1.2m with correctly spaced posts. For reactive clay sites, 50MPa sleepers are recommended. Contact us for project advice.
