Installing Removable Bollards using Receivers with Lids

Reliance Foundry’s premier removable bollards allow access to be granted or restricted to accommodate the changing needs of new streetscapes. The bollard is removed by unfastening a lock that connects the receiver’s lid to the bollard. The lid will then fall into place, covering the receiver. When a removable bollard is removed, the lid of the receiver can be closed to become flush with the surface grade. It is a convenient solution that provides flexibility of access control and eliminates tripping hazards.

With this installation method, the bollard is intended to act solely as a visual traffic deterrent to restrict or limit access to particular areas. It is important to note that the bollard will offer little impact resistance.

  • 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.

Before Installation

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

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

Ensure that the plan coincides with the site and familiarize yourself with the intended arrangement of the bollards.

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

Prepare the site for concrete
Please consult your local Building Code Department to determine the recommended digging depth below the frost line in your area. Choose this or 12″, whichever is greater. Add a minimum 6″ for holding the drain rock.*This is your total digging depth.

The diameter of the hole should extend a minimum of 10″.

Note: If the recommended digging depth below the frost line is greater than the depth of the receiver, be sure to provide adequate drainage by piping through the concrete and connecting to the drain rock layer underneath.

Dig the site
Center an auger on the installation mark and bore a hole to required measurements.

Ensure the area is properly formed to create a perimeter that will hold wet concrete.

Use a dirt tamper** to compact the soil below the intended surface.

Prepare the bollard and removable mount for designated location
Keep the bollard in its protective packaging.

Keep in mind that the receiver will be installed so that the bottom of the receiver plate is level with the finished surface of the concrete grade. This is recommended in order to create a slight berm with the concrete.

Add the drain rock
Add the drain rock to the installation site.

Pour the concrete

Mix the concrete
Ensure that the proper ratio of water and concrete mix is used.

The concrete should have a similar texture to moldable clay.

Place the receiver in designated location
Close the lid of the receiver and lower it into the designated location so that bottom of the receiver plate is level with the finished surface of the concrete grade. A slight berm is recommended.

Note: If necessary, temporarily insert the bollard (with packaging still on) into the receiver and use a level to ensure it is plumb. This will help to ensure the bollard is plumb to the surface before proceeding with pouring concrete.

Orientation of receivers should be parallel. When installing in a roadway, orient the receivers so that the lids close away from the direction of traffic. Place hinge toward oncoming vehicles so that lids left slightly open are pressed closed.

Pour the concrete
Note: If the recommended digging depth below the frost line is greater than the depth of the receiver, be sure to provide adequate drainage by piping through the concrete and connecting to the drain rock layer underneath.

Take care to pour the concrete evenly. The concrete should be slightly raised up towards the top edge of the receiver cover to create a slight berm.

Allow the concrete to cure
A minimum of 2–3 days should be given for concrete to cure before beginning construction projects on new concrete surfaces.

Note: Moisture in the environment and cool temperatures can significantly slow the process.

Install the bollard

Prepare the bollard
Ensure the concrete has cured.

Keep the bollard in its protective packaging. Carefully set the bollard near the installation site.

When ready to install, remove the protective packaging and lower it into the receiver.

Secure the bollard
Lift the lid of the receiver and set it over the stud. Attach the pad lock and fasten.

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
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.

*Recommended depth for drain rock is a minimum of 6″. Depth will also depend on local soil conditions, weather conditions, and engineering requirements.
**Dirt tamping is not required if working on undisturbed soil.
