Installing Bollards with Flanged Surface Mountings
A quick and easy surface-mount bollard installation method for Reliance Foundry’s decorative bollards
Reliance Foundry offers decorative bollards with a flanged base. These bollards can be installed on existing concrete using drop-in inserts. The function of these bollards is primarily aesthetic and offers little to no impact resistance.
Drop-in anchors should only be installed in fully cured concrete that is at least 4" thick.* All measurements in this installation guide assume a bare, level concrete surface.
Please note the parts and installation equipment required for this method will differ depending on the bollard model. Refer to the product drawing for each specific model to determine measurements.
What you will need
Flanged Bollard Base
Hex Head Bolt (refer to specific product drawing for sizes)
Washer (refer to specific product drawing for sizes)
Drop-In Concrete Insert (refer to specific product drawing for sizes)
Hexagon Socket Set Screw
3/16" Hex Key
Masonry Drill Bit (refer to specific product drawing for tool sizes)
Insert Setting Tool (refer to specific product drawing for tool sizes)
Wrench (refer to specific product drawing for tool sizes)
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 radius** of solid concrete around each mark.
Designate your hole marking
Keep the bollard in its protective packaging. Place the bollard over each center point marking so that the bollard’s middle coincides with the center point.
Use chalk to create drill-markings for each bolt.
Remove the 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 holes
Create pilot holes
Tap pilot divot holes in the center of each mark.
This will prevent the hammer drill or rotary hammer from drifting while boring the holes.
Set the depth control on the hammer drill (or rotary hammer)
Depth control settings will differ based on the bollard model. Refer to product drawing to determine the specific depth control settings.
Drill the holes
Drill holes to the required diameter and depth based on the bollard model. Refer to product drawings to determine specific measurements.
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 and clean the hole
Clear the holes of all debris and/or standing water using the vacuum.
Tap the drop-in insert into the hole
With the slotted end facing down, drive the drop-in insert (A) down until the top of the drop-in insert sits flush with (or just below) the surface of the concrete.
Set the concrete insert
Insert a setting tool (B) into each hole, then hammer down.
If a proper setting tool is not available, an equivalent flat-end punch can be used.
This will cause the internal expansion plug to set the concrete insert in place.
Set the bollard over the holes
Keep the bollard in its protective packaging. Carefully set the bollard base over the installation position so that the bollard's bolt holes are directly on top of the drilled holes and concrete inserts.
When ready to install, remove its protective packaging.
Secure the bollard
Place the washers over the holes on the bollard and set the bolts into place.
Use a wrench to tighten the bolts until secure. Tighten bolts evenly in a cycle.
Secure the bollard 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 plugs (C) over the set screw heads.
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
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.
*Concrete insert manufacturers such as www.ucanfast.com recommend a concrete depth for drop-in inserts.↩ **Concrete insert manufacturers such as www.ucanfast.com recommend an anchor spacing of 7-1/2", and a minimum edge distance of 9" for 100% performance.↩
