Grey Block Standard Half Height 20.71

The Adbri Grey Block Standard Half Height 20.71 is a half-height block that is commonly used for:

• Creating half-height courses in concrete block walls
• Adjusting wall heights without cutting full blocks
• Retaining walls and garden walls
•  Boundary walls and architectural masonry features

The dimensions of the 20.71 Half Height Block are 390mm (L) × 190mm (W) × 90mm (H).

This block is half the height of a standard 20.01 Block and is part of Adbri's 200 Series concrete masonry range.

Using a half block saves time on site, reduces cutting and material waste, provides a cleaner and more accurate finish, and helps maintain correct block alignment.

It is also a handy way to achieve specific wall heights where a standard block would add too much height.

Yes, the Adbri Grey Block Standard Half Height 20.71 can be used for retaining walls. However, it is always best to select your structural blocks based on your project requirements, engineering specifications, and local building regulations.
