Retaining Wall Kits & Bundles

Retaining wall kits bundle the three things every wall needs — concrete sleepers, galvanised steel posts and drainage — into one pre-matched, ready-to-build package. Each kit is assembled so the components are guaranteed compatible, which removes the most common cause of DIY ordering mistakes: mismatched sleeper thickness and post size. Australian-made materials, delivered Australia-wide by Retaining Walls Direct.

What's in a retaining wall kit

A typical kit pairs concrete sleepers with the correctly sized galvanised steel posts (C-channel or H-beam) and a drainage kit, plus an installation reference guide. Everything is matched so the sleepers seat correctly between the posts and the wall drains properly behind the face.

Who kits suit

• DIY homeowners building a garden, level-change or boundary wall who want a single, foolproof order.
• Builders & landscapers who want to order once and start the job without sourcing parts separately.
• Trade customers needing a complete materials package for a quoted job — open a trade account for bulk and repeat pricing.

How to size your kit

Wall height, post spacing and soil type determine how many sleepers and posts you need. Use the retaining wall calculator for an exact take-off, or read how to build a concrete sleeper retaining wall. Not sure which post size suits your sleeper? See the steel post sizing guide.

Drainage, council & engineering

Every kit includes drainage because water behind a wall is the number-one cause of failure — see our drainage guide. Walls over 1m, near boundaries or driveways, or on reactive soils should be designed by a qualified engineer and may need council approval — see walls over 1 metre and our state-by-state regulations guide.
