One installation that people think is complicated is installing a bollard pole. However, when you take it step by step, it is actually quite easy.
When you are done with this installation, whether it is to protect a parking lot, a storefront, or create a pedestrian zone, you will realize it is actually quite easy.
Most people think that they need a professional crew and heavy machinery. But the truth is, with the right tools, the right product, and a basic understanding of the installation process, you can do it yourself with confidence.
A poorly installed bollard is not only a waste of money but can also cause more problems than it solves. Also, it can lean over time, corrode at the base, or even get knocked over when it is needed most.
Here is how to get it done right, from the first dig to the final check.
1. Choose the Right Bollard for Your Situation
The kind of bollard pole you use will dictate how it is installed, so this is the first step.
Not all bollards serve the same purpose, so choosing the wrong one throws off the entire installation process, from the depth to the hardware.
- With steel pipe bollards, the bollards are installed directly into the ground, making them perfect for long-term installations.
- Base plate bollards bolt directly onto existing concrete, making them perfect for areas where you cannot core into the surface.
- Removable bollards use a ground sleeve system, so you can pull them out whenever access is needed.
- Crash-rated bollard requires a deeper footing, making it perfect for high-security installations.
Each bollard has a different installation process, depth, and hardware, so it is essential to know which one is best for the job before purchasing any materials.
The table below outlines each bollard type so you can pick the right one for your specific situation.
| Bollard Type | Best Use Case | Install Method |
|---|---|---|
| Steel Pipe Bollard | Permanent perimeter protection | Core into the ground or concrete |
| Base Plate Bollard | Surface mount, existing concrete | Bolt-down anchor |
| Removable Bollard | Controlled access areas | Ground sleeve system |
| Crash Rated Bollard | High-security, vehicle barriers | Deep embed or engineered footing |
2. Mark Your Layout and Call 811 Before Digging
Once you know your bollard type, mark exactly where each post goes.
Standard spacing between bollard posts is 4 to 5 feet on center. That gap is wide enough for foot traffic but narrow enough to stop a vehicle. Use spray paint or stakes to mark each point clearly.
Before any digging starts, call 811, the national dig safety line. This is a legal requirement across most of the United States and requires underground utilities, gas lines, and electrical cables to be marked at no cost to you.
Skipping this step puts lives at risk and exposes you to serious liability. Make the call, wait for the marks, then proceed.
3. Excavate or Core the Hole to the Right Depth
For in-ground bollard installation, the key to success lies in digging to the correct depth.
The general rule of thumb for in-ground bollard installation is to have at least one-third of the total height of the bollard below grade. So, for a four-foot bollard, you'll want to dig at least 18 to 24 inches, plus additional depth for a concrete footing at the bottom.
You'll want to use a power auger for digging through soil or a core drill for concrete or asphalt.
Once you have dug your hole to the right depth, you'll want to put in a small concrete footing at the bottom of the bollard installation site. This concrete footing will provide stability to the bollard and prevent it from sinking over time.
While the concrete footing is setting, remove any debris from the surrounding area.
4. Set the Bollard Plumb and Pour the Concrete
Lower the safety bollard into the hole and check if it is plumb on two sides using a level. Then pour concrete into the hole in layers and tamp down each layer to push out any air pockets.
Fill it to within a few inches of grade level so water drains away from the base rather than accumulating around it.
5. Install a Base Plate Bollard on Existing Concrete
Installing bollard posts on an existing slab is a faster, cleaner operation.
- Place the base plate in position; it will act as a template for your drill.
- Use a marker to mark each anchor location, then drill into the concrete using a hammer drill and a suitable drill bit. There is usually a minimum of three to four inches required for each anchor to penetrate the slab.
- Blow out each hole to remove dust using a can of compressed air, then install the anchor bolts and tighten all parts using the provided hardware.
6. Finish, Inspect, and Add a Cover
Once the bollard is in place and the concrete has cured, do a final inspection before declaring the task complete.
This includes ensuring that every bolt is secure, that there is no movement at the base of the post, and that it is at the correct height above grade, typically between 36 and 42 inches. Remove any locking mechanism to ensure it functions smoothly.
Place a bollard cover over the post to prevent rust and damage while giving it a finished look.
Bottom Line
A good installation of bollards is really all about preparation, product selection, and making sure you follow each step without taking any shortcuts.
- Take your time to ensure you get the right product for your needs.
- Dig it into the appropriate depth.
- Install it plumb, and let it cure.
If you do all these, you'll end up with a bollard that serves its purpose for years without any problems.

Frequently Asked Questions
1. How deep should a bollard pole be installed?
The depth of the pole should be one-third of the total length of the pole below the surface, which in most cases should be between 36 and 48 inches.
2. Can I install a bollard without digging?
Yes, it is possible to install a base plate bollard without digging, as it bolts directly onto the existing concrete.
3. What concrete mix works best for a bollard footing?
The most common mix for installing a bollard pole should be 3,000 to 4,000 PSI.
4. How far apart should bollards be spaced?
They should be spaced at a distance of four to five feet on center, as that would prevent cars from passing while still allowing pedestrians to pass through.
