anti-terrorism oil-hydraulic automatic bollard

The upper level of the foundation casing must be 1-2 cm higher than the walking level in order to limit the
amount of rain water that can get inside.
Pour A-class concrete all around the casing up to approx 5-10 cm below the walking level. Wait all the time
required for the concrete to set firmly (at least 7 days) and then finish the surface work.
It is most important that the casing be1-2 cm higher than the area finished level. In no way Talos C730 is to
become a water gathering basin.
Avoid areas where soil tends to sag to prevent the bollard from staying flooded. In case of snow, the flat
surface of the cover plate can be easily cleared even by heavy machanical means.
