A speedy and uncomplicated method for installing decorative bollards
Decorative bollards can be installed into existing concrete with an adhesive anchoring system. These bollards are used to define architectural perimeters, create architectural highlights, and act as visual traffic guidance devices. Please note that this installation method offers little impact resistance, and the function of the bollard is primarily aesthetic.
Reliance Foundry carries an epoxy-like, adhesive anchoring system that can be used to install bollards in decorative applications. In this process, the AC100+ Gold Adhesive Anchoring System1 is used to secure the bollard’s threaded rod.
What you will need
AC100+ Gold Adhesive Anchoring System
Threaded Bar 1"
Hex Nut 1"
Hexagon Socket Set Screw
Plastic Polyethylene Plug
1-1/8" Masonry Drill Bit
3/16" Allen Key
Hammer Drill or Rotary Hammer
To protect the finish, keep bollards in original packaging until the exact moment of installation
Handle with care to avoid scratching or damaging bollard surfaces as abrasions will lead to rust
Once scratched, bollards cannot be repaired to original form without re-finishing the entire surface
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.
For secure installation, ensure there is a minimum radius2 of solid concrete around each mark.
Drill the hole
Create pilot hole
Tap a pilot divot hole in the center of each mark.
This will prevent the hammer drill or rotary hammer from drifting while boring the hole.
Set the depth control on the hammer drill (or rotary hammer) to 4"
If depth control is not available, mark 4" on the masonry bit.
Drill the hole
Drill a hole that has a 1-1/8" diameter and 4" depth.
Drill on high speed, using the hammer function if available.
Check the masonry bit often to ensure it remains debris-free.
Secure the bollard
Clear the hole
Clear the hole of all debris and/or standing water using the vacuum.
Fill the hole with adhesive
Using the caulking gun, dispense the adhesive until the hole is two-thirds full.
To prevent air pockets from forming, withdraw the mixing nozzle slowly.
Insert the threaded rod
Push the threaded rod into the hole while turning to ensure positive adhesion.
The threaded rod should be inserted the full 4" into the hole.
Press a level vertically against the rod and ensure that it remains perpendicular.
*Note that a minimum of 45 minutes at 68˚F is required for the anchoring system to set. Do not disturb torque or load the anchor until adhesive has fully cured.
Place the bollard near the threaded rod
Keep the bollard in its protective packaging. Carefully place the bollard near the installation position.
When ready to install, remove its protective packaging.
Set the bollard over the threaded rod
Lift the bollard and lower it through the threaded rod. The top of the rod should extend past the bollard's receiver hole.
Ensure the threaded rod is centered in the bollard’s shaft.
*Metal bollards can be heavy—to prevent accidents and injuries, ensure the proper resources are available to lift bollards into place or onto their mountings.
Set the washer over the threaded rod
Place the washer over the threaded rod so that it rests on top of the shaft of the bollard.
Apply the 1" nut to the threaded rod and use a wrench to tighten until the bollard is secure.
Secure the bollard’s cap
Remove bollard cap from its packaging.
Place the cap on the top of the shaft of the bollard.
Secure and align the cap to the bollard base with the three set screws. Tighten in equal amounts to ensure that the cap remains centered.
Place the plastic polyethylene plugs (A) over the heads of the set screws.
Inspect the installation
From a distance, examine the plane of view.
Ensure the bollard is plumb to the surface, and the surface is flat.
Check the bollard for any signs of surface damage
Abrasions should be covered as soon as possible to prevent rust and ensure the proper life of the bollard. 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’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.
1. Please familiarize yourself with the MSDS for the adhesive before using↩ 2. Adhesive anchor manufacturers such as www.powers.com recommend a minimum radius of 5"↩
