Installing Solar Bollards using Adhesive Anchoring

Home > Bollards > Bollard and Post Cover Installation > Installing Solar Bollards using Adhesive Anchoring

Reliance Foundry solar light bollards can be installed in existing concrete with an adhesive anchoring system. For this installation, the AC100+ Gold Adhesive Anchoring System(1) is used to secure the bollard’s threaded rod. Adhesive installation is recommended for decorative applications to create architectural perimeters and aesthetically enhance environments. This installation technique offers limited impact resistance.

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.

For secure installation, ensure there is a minimum radius(2) 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. Use a brush to remove any remaining loose particles.

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

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

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 drilled hole
Set the bollard base upright and maneuver it so the center lines up with the drilled hole.

Insert the threaded rod
Lower the threaded rod through the bollard’s shaft. Insert the threaded rod the full 4″ into the hole while turning for positive adhesion. The rod should be centered in the bollard’s shaft and should extend no more than 23″ above grade.

Note: 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.

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.

Install the solar light cap

Connect the battery
With the lighting assembly still in its packaging, locate the battery’s wire plug and connect to the 2-pin socket attached to the light fixture.

Once connected, the lighting fixture will run a test pattern and may flash for 3–5 seconds.

Note: If the light does not flash, please stop installation and contact Reliance Foundry’s sales department for assistance.

Secure the solar light cap
Remove solar light cap from its packaging.

Place the solar light cap on top of the shaft of the bollard.

Secure the solar light cap to the bollard base with the three bolts and tighten equally.

Note: For asymmetrical lighting, consider the lighting pattern. When attaching the solar light cap, twist it to the desired lighting pattern before bolting down.

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 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.

1. Please refer to the adhesive manufacturer’s MSDS (included in shipment) before using.

2. Adhesive anchor manufacturers such as www.powers.com recommend a minimum radius of 5″.
