APT FLEX BOLLARD RANGE – INSTALLATION INSTRUCTIONS
1 INTRODUCTION
This document outlines the instructions that should be followed when installing the APT Flex range of static bollards. Please follow them carefully.
2 CHOOSING THE KIND OF BOLLARD
The two different APT Flexbollards have different anchoring systems, each of which is designed for a specific bollard installation.
- Anchoring with concrete footing. Bollard is set into concrete footing in the ground.
- Bollard is attached to the surface by mechanical means (mechanical anchoring or chemical anchor).
The table below provides a description of the two applications.

Installing bollards with a concrete footing in a concrete surface is not advised due to the complexity of digging the hole, though the bollard will work correctly.
A surface-attached bollard installed by mechanical means on a soft surface will not be reliable because it will be uprooted when extreme force is exerted on the bollard.
3 INSTALLATION OF BOLLARDS WITH CONCRETE FOOTING
To install the bollard, a hole must be dug that is of a suitable size to house the concrete footing and is appropriate for the place of installation. For soft surfaces, the footing should be wider and the hole deeper.
The hole should be filled with plain concrete. Do not use mortar, quick-drying cement, poor cement or other materials because they may not be strong enough.
The bollard should be placed vertically and the top of the upper ring should be flush with the ground.
The bollard should not be filled with concrete. This will keep it from working properly. Keep the concrete from rising inside the bollard beyond the level of the ground.
To guarantee high bollard performance, protect the bollard from vehicle impacts until the concrete has hardened.
DIMENSIONSOF CONCRETE FOOTINGLength B / Same as length A + 5 cm. / These are the measurements of the smallest possible hole for the footing. They should be increased when the bollard is installed in soft ground.
Length D / Same as length C + 5 cm.
4 INSTALLATION OF SURFACE-ATTACHED BOLLARDS
Bollards equipped with a base are designed to be mechanically attached to the surface.
As a suggestion, we recommend using Fischer FSA sleeve anchors or Fischer FIS V chemical anchors or similar. The choice of the actual anchor used should be based on the characteristics of the ground where the bollard will be installed.
An M14 thread should be used for both anchor types. A smaller size could bend or break when sufficient force is exerted on the bollard.The length of the fixation elements depends on the terrain in which it should apply the bollard. In cement pavements can be used a standard anchor (length approximate 120mm). In flagstone pavements it must insure that the anchor remains fixed, as minimum 120 mm, in the hard layer below the flagstone pavement.
The large metal tightening washer on the anchoring should always be assembled to keep the base of the bollard from bending.
