Hollow blocks
Lighter walls, better thermal performance, lower cost per square metre.

Coverage, with the working
A 390 x 190 mm face plus a 10 mm joint gives a coordinating size of 400 x 200 mm, so 1 / (0.400 x 0.200) = 12.5 units per square metre of single skin.
- Units per m², single skin
- 12.5
- Units per m², double skin
- 25.0
- m² per pallet
- 7.2
- Pallet mass
- 1 350 kg
A single skin of hollow blocks gives a 190 mm wall.
What it is for
Where it goes.
- Boundary walls
- Industrial structures
- Retaining structures
- Commercial projects
Why builders choose it
Four reasons, spelled out.
01
Lightweight
Hollow cores cut the mass per square metre, which speeds up laying and reduces the load carried into the foundation.
02
Reduced construction costs
The face is 390 x 190, so 13 units cover a square metre against 52 stock bricks. Fewer units, fewer joints, less labour.
03
Improved thermal performance
The voids break the conductive path through the wall, so the building holds temperature better than a solid single skin.
04
Easy installation
Cores can be reinforced and filled where the design calls for it, which makes the same unit work for boundary walls and retaining structures.
