Pour concrete to construct a foundation of 500 mm× 500 mm (19.69''× 19.69'') (L × W), and make
sure that the depth is between 150 mm–200 mm (5.91''–7.87''). Depths that do not fall within this
range will greatly influence the accuracy of radar detection.
●
Use concrete of at least grade C15.
●
Bury foundation bolts in the foundation. Make sure that the bolts are exposed 100 mm (3.94'')
above the foundation.

accessories of the Barrier.
