Other strip Reinforcement Methods:
 
Figure 16.1
The York method:
?     Horizontal galvanized steel or glass reinforced plastic strips are attached to vertical pole which in 
turn provide a connection between the hexagonal facing elements.
?     Strips are allowed to slide vertically so that settlement of the backfill can be accommodated 
 without stressing the face panel.
