Bollards serve various purposes, from guiding traffic to protecting pedestrians. When installing bollards, the base is as important as the bollard itself.
With asphalt surfaces being a common choice for roadways and parking lots, understanding the different bollard base options can help ensure durability and effectiveness.
This article discusses the various types of bollard bases suited for asphalt surfaces, their pros, cons, and considerations.
Types of Bollard Bases
When it comes to bollard bases, there are a few common types you might encounter. Each type has unique characteristics that can influence its suitability based on specific needs.
Concrete Footing
Concrete footings provide a solid foundation for bollards. This type involves digging a hole in the asphalt and filling it with concrete to create a stable base. The bollard is then anchored into the concrete.
Strength: Concrete footings offer excellent stability and strength. They can withstand heavy impacts, making them ideal for high-traffic areas.
Installation: The installation process requires heavy machinery and skilled labor. This can increase the overall cost and time for the project.
Surface Mount
Surface mount bases consist of a plate that bolts directly onto the asphalt surface. This method is generally quicker and easier to install.
Ease of Installation: Surface mounts can be installed without extensive digging or heavy machinery. This is advantageous for projects with tight timelines.
Stability Issues: While convenient, surface-mounted bollards can be less stable than those with concrete footings, especially in high-traffic areas. They are more susceptible to being dislodged if hit with significant force.
In-Ground Mount
In-ground mounting involves placing the bollard directly into a hole in the asphalt. This method is similar to concrete footings but does not require concrete. Instead, the bollard is secured with gravel or compacted asphalt.
Cost-Effective: This method can be more economical than using concrete, as it requires less material and labor.
Durability: While generally stable, in-ground mounts may not offer the same level of protection against impacts as concrete foundations.
Removable Bases
Removable bases allow for the bollard to be taken out when needed. These bases typically use a sleeve that remains in the ground.
Flexibility: The ability to remove bollards is useful in situations where space is needed for events or maintenance.
Security Concerns: If not secured properly, removable bases may be more vulnerable to theft or vandalism.
Factors to Consider When Choosing a Base
Selecting the right bollard base involves more than just picking a type. Several factors come into play that can impact your decision.
Traffic Volume
The amount of traffic in an area significantly influences the type of bollard base to use. High-traffic zones benefit from stronger bases, like concrete footings, while lower-traffic areas may be fine with surface mounts.
High-Traffic Areas: For locations with heavy vehicle flow, robust bases are necessary to withstand the forces exerted upon them.
Low-Traffic Zones: In quieter areas, simpler bases may suffice, providing adequate protection without the need for extensive installation.
Environmental Conditions
Weather can affect not only the installation process but also the longevity of the bollard bases. Consider how environmental factors may play a role.
Temperature Variations: In areas with extreme temperature changes, certain materials may expand and contract, leading to potential damage over time.
Moisture: Regions with lots of rain or snow may require bollard bases that can withstand water pooling or freezing, ensuring long-term durability.
Aesthetic Considerations
While functionality is key, the appearance of the bollard and its base can also matter, especially in areas where aesthetics are essential.
Design: The base should align with the overall design of the location. Some bases can be painted or covered to blend in with surroundings.
Visibility: In addition to aesthetics, the visibility of the bollard is crucial for both safety and guiding traffic.
Cost Analysis
Budget constraints often play a significant role in selecting bollard bases. Understanding the costs associated with each type can aid in making an informed decision.
Installation Costs
Concrete footings generally incur higher labor and material costs compared to surface mounts. Installation efficiency can vary based on the type of base chosen.
Labor Costs: More complex installations necessitate skilled workers, driving up labor costs.
Material Costs: The choice of materials, especially for concrete, can also impact the overall budget.
Long-Term Maintenance
Considering the long-term maintenance costs is essential when selecting a bollard base. Some bases may require more upkeep than others.
For commercial properties, it’s especially important to prioritize durable options, as maintaining asphalt surfaces for businesses helps reduce downtime and preserve the safety and appearance of high-traffic areas.
Durability: Those that need frequent repairs or replacements can lead to higher expenditures over time.
Environmental Resistance: Bases that withstand environmental wear will likely incur fewer maintenance costs, providing greater value in the long run.
Local Regulations and Compliance
Local laws can dictate various aspects of bollard installation, including types and sizes of bases. Understanding these regulations can save time and expense.
Zoning Laws
Check local zoning codes that may govern where and how bollards can be installed. These rules can often dictate the types of materials and dimensions allowed.
Consultation: Engage with local authorities to ensure compliance, avoiding potential fines or mandated removal later.
Safety Standards
Certain standards may apply to bollard installations, especially concerning pedestrian safety and vehicle impact protection.
Adherence: Following safety guidelines not only protects the public but also mitigates liability risks for property owners.
Case Studies: Successful Installations
Examining case studies of successful bollard installations can offer valuable insights into the effectiveness of various base types.
Urban Park Installation
In a busy urban park, concrete footings were used for bollards around playground areas. This choice ensured stability in a high-traffic spot, successfully preventing vehicle access while enhancing safety.
Shopping Center Implementation
In a shopping center, removable bases were installed to allow flexibility for events. This approach provided the needed traffic guidance while allowing for easy adjustments based on seasonal requirements.
Residential Community Application
A residential community opted for surface mounts for their bollards, balancing cost and functionality. This choice worked well in a low-traffic area, proving effective without significant investment.
