Flexifoot Sleeves Specification

INSTALLATION

We recommend installing our bollards using a steel pipe.

The depth of the foundation can be between 1 metre to a minimum of 55 cm where surface conditions allow but only if the impact can be absorbed without the foundation becoming misaligned. If you choose to reduce the depth of the foundation it is important that extra concrete is cast around the pipe to compensate for the shorter length. The more concrete around the pipe the higher the impact force can be absorbed without misaligning the pipe.

Bollards can be installed in any surface.

We recommend using steel installation pipe. (Please see table below)

Installation pipe increases the functioning of the bollard and its flexible strengths.

• Prepare your foundation (recommended Ø200mm x maximum 1000mm depth)
• We recommend an opening of approximately 200 mm diameter. The recommended depth for the  foundation is approximately 1000mm but in order to avoid the risk of drilling into wires, pipes or large obstructions it is possible to reduce the depth from 1000mm to a minimum of 550mm, but only if the impact can be absorbed without the foundation becoming misaligned. If you choose to reduce the depth of the foundation it is important that extra concrete is cast around the pipe (see drawing below) to compensate for the shorter length. The more concrete around the pipe the higher the impact force can be absorbed without misaligning the pipe It is imperative that the foundation has a minimum depth to endure the forces of impact and ensure that the bollard will raise to upright position after a collision. 
• Secure installation pipe in to the foundation.
• Fill the foundation with gravel/sharp sand to a level that will achieve the required bollard height above the ground.
• Slot bollard in to installation pipe and secure with sharp sand.
