Installing Flexible Bollards into New Concrete

Home > Bollards > Bollard and Post Cover Installation > Installing Flexible Bollards into New Concrete

Flexible bollards can be set into new concrete by positioning the bollard in its intended location and then pouring concrete. The bollard becomes a fixed device for lane demarcation or for creating traffic friendly perimeters. Flexible bollards will bend up to 90° upon impact to reduce damage to vehicles, making them ideal for traffic applications.

It is important to note that with this installation method, the bollard’s function is strictly visual and offers little impact resistance.

Please refer to the product drawing for each specific model to determine some of the measurements in this installation guide.

Before installation

Study the site plans
Site plans are generally created by the architect of the project.

Refer to site plans to locate the precise center point of each bollard.

Ensure that the plan coincides with the site and familiarize yourself with the intended arrangement of the bollards.

Check for hazards
Always check for hazards such as water pipes, gas lines, and underground wiring before digging.

Prepare the site for concrete
Please consult your local Building Code Department to determine the recommended digging depth below the frost line in your area.

Dig below the recommended digging depth—or to the required depth for the bollard—whichever is greater.

Note: The required depth for the bollard differs based on the bollard model. Refer to product drawings to determine specific depth measurements.

The diameter of the hole should extend a minimum of 2″ from the sides of the bollard base.

Center the auger on the installation mark and bore a hole to the required measurements.

nsure the area is properly formed to create a perimeter that will hold wet concrete.

Use a dirt tamper to compact the soil below the intended surface.

Prepare the bollard for designated location
Keep the bollard in its protective packaging and place near the site.

When ready to install, remove packaging and scrunch up paper or newspaper and put inside the hollow bottom of the bollard to prevent debris from entering.

Pour the concrete

Mix the concrete
Ensure that the proper ratio of water and concrete mix is used.

The concrete should have a similar texture to moldable clay.

Place the bollard in designated location
Lower the bollard into designated location. The bollard should be installed so that a predetermined portion of the bollard will sit below the finished surface of the concrete grade.

Refer to product drawings to determine specific measurements.

Pour the concrete
Take care to pour the concrete evenly, ensuring the surface is level.

Hold a level against the side of the bollard and ensure that it remains plumb.

Note: Once the concrete has cured, there will be no way to make any adjustments.

Allow the concrete to cure
A minimum of 2–3 days should be given for concrete to cure before beginning construction projects on new concrete surfaces.

Note: Moisture in the environment and cool temperatures can significantly slow the process.


Inspect the installation
From a distance, examine the plane of view.

Ensure the bollard is plumb.

Check the bollard for any signs of surface damage
For damage repair or other servicing needs, please contact Reliance Foundry’s sales department.

Care and maintenance

Reliance Foundry manufactures its products to the highest design standards to ensure their durability. Reliance Foundry’s bollards are finished with long-lasting powder coating. In most North American environments, routine inspections and cleaning will ensure that bollards retain their aesthetic appeal. Proper care and maintenance are required to maintain the finish and ensure a full service life.
