NOTE

1. Strength is important if good wearing properties are required

2. The laying pattern is important for heavy loads as it helps distribute the pressure on the subbase.

3. The interlock shape and thickness of the paver improves the ability to withstand point loads.

4. The design and quality of the subbase is important for overall load carrying ability

5. Refer to the CMA manuals on Concrete Block Paving for more information on design, installation and site management.
