(Optional) If no foundation bolts are buried, you can use the expansion bolts provided in
the accessories of the Barrier.
After the concrete foundation is hardened, drill 4 holes with diameter of 16mm (0.63'')
for installing the Barrier.
The drilled holes and the installation position should meet the requirements shown in
Figure 3-4 to facilitate installing the metal plates and fixing the Barrier.
