Bollards are crucial to urban planning and public safety, but their placement and installation raise several questions. One common question we get is whether bollards can be installed on pavement. This blog post explores the nature of bollards, their placement on pavements, and the places their installation might be inappropriate or prohibited.
What Are Bollards in Construction?
Bollards are sturdy, short vertical posts designed to control traffic, enhance safety, and protect properties. They come in various materials, including steel, concrete, plastic, and wood, and serve multiple functions:
- Traffic Control: Direct vehicle and pedestrian flow.
- Property Protection: Guard buildings, equipment, and public spaces from accidental or intentional vehicle collisions.
- Security: Enhance security measures by preventing vehicular access to sensitive areas.
- Aesthetic Enhancement: Add visual appeal to urban landscapes with decorative designs.
The Different Types of Bollards
Bollards are versatile and come in several types, each tailored to specific needs and situations:
- Fixed Bollards: Permanently installed to provide continuous protection and control.
- Removable Bollards: These can be temporarily removed to allow vehicle access when needed.
- Retractable Bollards: These can be lowered into the ground to provide flexible access control.
- Flexible Bollards: Designed to bend upon impact, reducing damage to vehicles and infrastructure.
- Decorative Bollards: Aesthetic designs that also serve practical functions, blending security with visual appeal.

Pavement Installation Feasibility
Installing bollards on pavement is feasible and often necessary for various applications:
- Pedestrian Safety: Protecting walkways and pedestrian zones from vehicular intrusion.
- Traffic Management: Controlling and directing traffic flow in parking lots and urban streets.
- Property Protection: Shielding storefronts, outdoor cafes, and public spaces from vehicle damage.
Considerations for Pavement Installation
When installing bollards on pavement, several factors need to be considered to ensure effectiveness and safety:
- Pavement Type: Different pavements (asphalt, concrete, brick) require specific installation techniques.
- Foundation: Ensuring a solid foundation for secure bollards and preventing tipping or dislodgement.
- Spacing: Adequate spacing to allow pedestrian flow while providing practical barriers.
- Visibility: Ensure bollards are visible to drivers and pedestrians to prevent accidents.
Steps for Installing Bollards on Pavement
1. Assessment of the Site
Evaluate the pavement and traffic conditions to determine the best bollard type and installation method.
2. Preparing the Foundation
Excavate the pavement to create a stable foundation, often involving concrete footings.
3. Installing the Bollards
Secure the bollards into the prepared foundation, ensuring they are plumb and level.
4. Finishing the Process
Fill and seal around the bollards to seamlessly integrate them with the surrounding pavement.
Where should bollards not be placed?
While bollards are versatile, there are specific locations where their installation might be inappropriate or even hazardous:
- Narrow Pathways: Installing bollards in narrow pathways can obstruct pedestrian movement and pose tripping hazards.
- Emergency Access Routes: Bollards should not block routes required for emergency vehicle access.
- Residential Driveways: Installing bollards in residential driveways can inconvenience homeowners and visitors.
- Historical Sites: Bollards might not be suitable in areas where they can disrupt the historical integrity of a site.
Regulatory and Safety Considerations of Bollards
Regulations and safety standards often dictate where bollards can and cannot be installed:
- Local Zoning Laws: Adherence to local laws and regulations is crucial to avoid legal issues.
- ADA Compliance: Ensuring bollards do not obstruct accessibility for people with disabilities.
- Visibility and Lighting: Bollards should be placed in appropriately lit areas where they can become hazards.
The Alternatives to Bollards
In locations where bollards are not suitable, alternative safety and traffic control measures can be considered:
- Planters: Large, heavy planters can serve a similar purpose while adding aesthetic value.
- Benches: Strategically placed benches can control pedestrian flow and prevent vehicle access.
- Barriers and Railings: Permanent barriers and railings can provide robust protection without bollards.
Bollards enhance safety, security, and traffic management in various environments. Installing bollards on the pavement is feasible and highly effective for protecting pedestrian zones, managing traffic, and safeguarding properties. However, their placement requires careful consideration of the pavement type, foundation requirements, spacing, and visibility to ensure they serve their intended purpose effectively.
