Installation

6.1

Foundation construction: barrier

A stable position of the barrier casing is imperative. We recommend a foundation with the following
minimum requirements. If there is a risk of frost, the foundation must be constructed in a way as to
ensure protection against frost – so the ground does not rise. All necessary ductwork and wires
have to be led out of the center of the barrier's pedestal.
• Duct for power supply
• Duct for Photocell
• Duct for control wires
• Duct for loop connection 1
• Duct for loop connection 2
• Etc.

The upper pedestal area is to be constructed in a smooth, flat and absolutely horizontal way with
regard to the road, so the barrier casing can be mounted vertically. The used concrete should
comply with hardness BH PC 250 (25N/mm2). The pedestal must be constructed with solid steel
reinforcement. The drilled holes are to be designated according to the dimensions and to be
fastened to the composite anchors (Ø 20mm x 110mm).
