Installing Concrete Bollards in Existing Concrete

Home > Bollards > Bollard and Post Cover Installation > Installing Concrete Bollards in Existing Concrete

Reliance Foundry’s concrete bollards offer versatile design in a range of unique styles to complement any building or landscape. Concrete bollards are reinforced with steel rebars for impact protection and suitable for use in urban environments such as parking lots and other high-traffic areas. With this installation method, an adhesive anchoring system such as the AC100+ Gold Adhesive Anchoring System(1) is used to fix the steel rebars into the existing concrete.

Before installation

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

Clean the surface
Dirt and debris can affect the line of sight and disrupt placement of the bollards.

Use a broom or pressure washer to clean the concrete surface prior to bollard installation.

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

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

Designate your hole markings
Each bollard ships with a fitted rebar template.

Use the template to mark accurate installation holes around the center point of each bollard.

Note: Be sure to make any necessary adjustments to the orientation now. Once drilled and installed, there is no way to rotate the bollard.

Drill the hole

Create pilot hole
Tap a pilot hole in the center of the hole marking.

This will prevent the rotary hammer from drifting while boring the hole.

Set the depth control on the hammer drill (or rotary hammer) to 6″
If depth control is not available, mark 6″ on the masonry bit.

Drill the hole
Drill a hole that has a 5/8″ diameter and 6″ depth.

Ensure the drill is level. Drill on high speed, using the hammer function if available.

Check the masonry bit often to ensure it remains free of debris.

Clear the hole
Clear the hole of all debris using a vacuum. Use a brush to remove any remaining loose particles.

Set the bollard

Fill the hole with adhesive
Using the caulking gun, dispense the adhesive from the bottom up until the hole is one-quarter full.

To prevent air pockets from forming, withdraw the mixing nozzle slowly.

Lower the bollard
Set the bollard over the site, lining up the steel rebars with the holes.

Insert steel rebars into the holes and lower.

Use a level to ensure that the bollard is plumb and make any necessary adjustments.

Note: A minimum of 45 minutes at 68˚F is required for the anchoring system to set. Do not disturb until adhesive has fully cured.


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.
