Frequently Asked Questions

What are retaining blocks used for?

Retaining blocks are used to build garden walls, raised garden beds, terraced slopes, and planter borders. They hold back soil to create level, usable space in a sloped yard, or simply add structure to garden beds.  Choose from Gardenwall blocks in charcoal, portstone, and Hawkesbury yellow tones, WedgeBLOK for curved walls, or standard hollow blocks for core-filled structural work. 

What's the difference between large and small retaining blocks?

Small retaining blocks, like the Gardenwall range, are light and easy to handle, making them ideal for DIY garden borders, raised beds, and low walls. Large retaining blocks, such as 200mm hollow blocks, are used for structural walls that hold back significant soil and are usually core-filled with concrete. As a rule of thumb: the taller the wall, the bigger and stronger the block you'll need.

What types of retaining blocks do you stock?

We stock three National Masonry ranges, each suited to a different job.

  • Gardenwall — a split face block with an exposed aggregate finish, available in charcoal, portstone, and Hawkesbury yellow. Builds straight or curved walls up to 1 metre high under ideal conditions, with no extra corners or caps required.
  • Hollow grey blocks — the structural choice, in 100mm, 150mm, and 200mm sizes. Hollow cores make them easy to handle and ready for core filling on bigger walls.
  • WedgeBLOK — a tapered block for edging and low walls that handles straight lines, curves, circles, and even fire pits with no gapping. Its colours match National Masonry's Esplanade pavers, so your edging and paving can tie together.

All three are made locally by National Masonry to Australian Standards.

What do I need behind a retaining wall for drainage?

Good drainage is what keeps a retaining wall standing. Behind the wall, lay free-draining crushed rock or screenings with a slotted ag pipe at the base to carry water away. Without drainage, water builds up and pushes against the wall, which is the most common reason walls fail.

Can I use retaining blocks for a raised garden bed?

Yes, retaining blocks are one of the most popular ways to build raised garden beds. Gardenwall blocks are ideal, as they're easy to lay and don't need mortar for low beds. Once built, fill with quality soil, top with mulch, and you're ready to plant.

Do you deliver retaining blocks across Melbourne?

Yes, All Green delivers retaining blocks across Melbourne and surrounds, straight to your home, garden, or worksite. Blocks are heavy, so delivery is often the most practical option, especially for larger walls.
