How to install bollards?

Installing bollards depends on their type, location and use, but here's a clear step-by-step guide to the most common method: permanent underground bollards (e.g., steel safety bollards embedded in concrete).

How to install a bollard (drilled or cast-in)

Tools and materials needed:

Bollards

Concrete mix

Gravel base (optional)

Reinforcing steel or anchors (if needed)

Auger or drilling machine

Leveling device

Tape measure

Safety equipment

Step-by-step guide (cast-in-place concrete)

1. Plan and Mark Locations

Measure and mark where each bollard will be installed.

Follow local building codes for spacing and location (e.g., space bollards at least 36 inches apart to allow for wheelchair access).

2. Dig holes

Drill or dig a hole 18-36 inches deep and approximately 12 inches wide (depending on bollard type and size).

For drilled installations, use a concrete drill to drill holes in the existing pavement.

3. Prepare the base

Add gravel for drainage (if needed) and compact.

Insert rebar or anchors into the bollard base (if reinforcement is required).

4. Place bollards

Place the bollard vertically into the hole.

Use a level to ensure it is vertical.

5. Pour Concrete

Fill the hole with ready-mixed concrete, making sure the concrete completely encases the base.

Smooth the surface to obtain a clean finish.

Allow the concrete to cure for 24-72 hours, depending on the conditions.

6. Optional: Add Bollard Cover

For aesthetics or protection, apply bollard sleeves or bollard covers after the installed posts have cured.

 

Other Installation Types:

Type	Notes
Surface-Mounted Bollards	Bolt to concrete using anchor bolts - easier to install, less impact resistance.
Removable Bollards	Set into locking ground sleeves - ideal for areas needing occasional vehicle access.
Retractable or Automatic Bollards	Require electrical/hydraulic installation - often for high-security or smart access zones.
