Certificate type
Dense concrete blocks.
Application
Coursing Blocks can be used for the following applications:
- Infill above doors and windows.
- Coursing at floor and ceiling level.
- Between timber joists.
- High-strength walls.
Description
Coursing Blocks are produced from the same material as standard blocks, providing a uniform performance throughout a wall.
They can be used internally or externally in loadbearing, and non-loadbearing situations.
Loadbearing walls should not be constructed with coursing blocks, as the sole masonry unit.
Features and benefits:
- Avoids cutting and wastage of full-size blocks.
- Convenient to handle.
- Maintains uniform performance of the wall.
