Installing Bollards with Concrete Anchors
A simple and cost-effective method for installing bollards in decorative applications
Bollards can be installed on existing concrete surfaces with drop-in anchors offered by Reliance Foundry. By drilling into a concrete’s substrate and inserting a concrete anchor and threaded rod, a bollard can be used in decorative applications to create architectural perimeters. It is important to note that, with this installation method, the function of the bollard is decorative and the bollard will offer little impact resistance. This installation method is intended for bollards that aesthetically enhance environments, decorate landscapes and highlight architecture.
Installation Equipment Required
- Measuring Tape
- Hammer Drill or Rotary Hammer
- 1" Carbide-Tipped Masonry Drill Bit
- Small Masonry Chisel
- Can of Water for Cleaning Drill Bit
- Chalk Line
- 1½" (38mm) Wrench
- ⅜" (9mm) Allen Key
- Hammer optional
- Masonry Nail optional
- Touch-Up Paint (can be easily sourced at automotive part stores)
Surface Preparation and Determining Layout
* NOTE: Bollards should be left in their packaging until the exact moment of installation
- Ensure that underground utility lines and pipes pose no risk:
Because installing bollards requires penetration of the concrete surface, it advisable to check for water pipes, gas lines and underground wiring. A core drill, in advance of an x-ray, may be required. Taking the proper safety precautions can help to eliminate expensive “down time” and prevent accidents.
- Clean surface:
Dirt and debris can affect the line of sight and disrupt placement of the bollards. Use a broom, an electric leaf blower or a pressure washer to clean the surface of the concrete on which the bollards will be placed.
- Study site plans:
Site plans are generally created by the architect of the project. The architect will mark the intended location of each bollard on the plan. Ensure that the plan coincides with the site and familiarize yourself with the intended arrangement of the bollards.
- Measure the placement of each bollard:
Use chalk to mark the centre point of each bollard. Bollards are generally spaced 4’ apart. Many contractors find it beneficial to snap a chalk line to achieve a uniform look in the bollard row .
Drilling the holes
- Create pilot holes:
Use a small masonry chisel to tap a starter pilot hole in the centre of each hole marking. This will prevent the rotary hammer from drifting while boring the hole.
- Set the depth control on the Hammer Drill (or Rotary Hammer) to 3⅝":
Most hammer drills have a depth setting or depth control bar. If depth control is not available, use masking tape to mark 3⅝" on the masonry bit.
- Drill the hole:
Apply force to rotary hammer and create a hole that has a one inch diameter and a depth of 3⅝". Drill on high speed, using the hammer function if available. Check the masonry bit often to ensure it remains debris-free. If the masonry bit becomes clogged with concrete dust, rinse it in the can of water. If an overly hard patch of concrete is encountered, it can be broken with a masonry nail and hammer.
Securing the Bollard
- Tap the concrete anchor into the hole:
Ensure that perforated side faces down and use a hammer to drive the anchor until its top sits flush with the surface of the concrete. This will set the anchor in place.
- Set the bollard over the hole:
With the packaging left on, carefully set the bollard near the installation position and remove its protective packaging. Once the packaging is removed, place the bollard over the freshly drilled hole and insert the threaded rod into the concrete anchor.
- Tighten the threaded rod and secure the bollard:
With your hand, tighten the threaded rod until it reaches a depth of approximately 1½” in the concrete anchor. Ensure that the top of the threaded rod does not extend higher than 32” from the concrete’s surface. 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 tighten it 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. Then, secure the cap to the shaft by tightening the three set screws with equal amounts of torque to ensure that the cap remains centered. The set screws are composed of stainless steel and the insert holes on the bollard cap are lined with stainless steel to prevent rust. Place the provided plastic caps over the heads of the set screws.
- Inspect the Installation
At a distance, examine the plain of view. All bollards should appear to be perpendicular with the surface of the concrete. On level surfaces, hold a level vertically against the side of the bollard to ensure that it is plumb to the surface.
- Check the bollard for any signs of surface damage:
If the bollard was scratched or scraped during installation, it can be repaired with touch up paint, commonly found at automotive stores. Abrasions must be covered to avoid rust and ensure the proper life of the bollard.
Care and Maintenance
Reliance Foundry manufactures its products to the highest design standards to ensure their durability. Reliance’s line of bollards are finished with a long-lasting powder-coating. This powder-coated finish will protect the bollard in typical North American climates, however, proper care and maintenance is required. In most environments, regularly-performed inspections and routine cleaning will ensure that a bollard retains its aesthetic appeal and does not become damaged by the elements.
