1. Flexible laying on flexible foundation:

Pave 25-50mm sand on the subgrade with leveling, compaction and compactness of more than 90%, and pave road bricks on the flat sand. The joints between bricks are filled with spun yarn.

2. Flexible laying on semi-rigid Foundation:

After fully mixing according to the proportion of cement: sand = 1:7, lay it on the leveled and compacted subgrade with a thickness of 30-50mm, then lay road bricks on it, and fill the brick joints with yarn. Finally, sprinkle water on the brick surface, and the water seeps into the cushion through the brick joint, which can effectively enhance the bonding force with the cushion.

3. Flexible laying on rigid foundation:

Foundation: it must be leveled, compacted and the compactness shall be more than 90%.
