Installing Bike Bollards with Flanged Surface Mountings

Reliance Foundry’s line of bike bollards offer convenient bicycle storage while minimizing obstruction caused by improper bike parking. Their aesthetic designs decorate landscapes and enhance surrounding architecture. Bike bollards with flanged bases can be installed on existing concrete using drop-in inserts. Drop-in inserts 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. It is important to note that with this installation method, bike bollards will provide limited impact resistance.

  • To protect the finish, keep bike bollards in original packaging until the exact moment of installation.
  • Handle with care to avoid scratching or damaging bike bollard surfaces as abrasions will lead to rust.
  • Once scratched, bike bollards cannot be repaired to original form without re-finishing the entire surface.

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 bike bollards.

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

For secure installation, ensure there is a minimum radius** of solid concrete around each mark.

Designate your hole marking
Keep the bike bollard in its protective packaging. Place the bike bollard over each center point marking so that the bike bollard’s middle coincides with the center point.

Use chalk to create drill-markings for each bolt.

Remove the bike bollard.

Note: Be sure to check the orientation of the bike bollard arms and make any necessary adjustments now. Once drilled and installed, there is no way to rotate the bike 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 hole of all debris and/or standing water using the vacuum.

Tap the drop-in concrete insert into the hole
With the slotted end facing down, drive the drop-in concrete insert (A) down until the top of the drop-in insert sits flush with the concrete surface.

Ensure that the top is perfectly level.

Set the drop-in concrete insert
Insert a setting tool (B) into the threaded 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 drop-in concrete insert in place.

Set the bike bollard over the holes
Keep the bike bollard in its protective packaging. Carefully place the bike bollard base over the installation position so that the bike bollard’s holes are directly on top of the drilled holes and concrete inserts.

When ready to install, remove the protective packaging.

Secure the bollard
Place the washers over the holes on the bike bollard and set the bolts into place.

Use a wrench to tighten the bolts until secure. Tighten bolts evenly in a cycle.

Secure the bike bollard cap
Remove the bike bollard cap from its packaging.

Place the cap on the top of the shaft of the bike bollard.

Secure and align the cap to the bike 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 bike bollard is plumb to the surface, and the surface is flat.

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