When specifying or installing bollards, avoiding common mistakes is essential to ensure maximum safety, proper functionality, and long-term durability. Poor planning or incorrect installation can significantly reduce their effectiveness.
Common mistakes to avoid:
- Incorrect spacing
Placing bollards too far apart can allow vehicles to pass through, while spacing them too close together can restrict pedestrian and wheelchair access. As a general guide, aim for 1.2–1.5 metres centre-to-centre to balance security and accessibility. - Insufficient foundation depth
One of the most frequent issues is installing bollards too shallow. This weakens impact resistance and stability. Fixed steel bollards should typically be embedded 300–500mm into concrete, depending on height and application. - Choosing the wrong type of bollard
Not all bollards serve the same purpose. For example:- Retractable or removable bollards suit areas needing occasional access
- Fixed bollards are best for permanent protection
- Crash-rated bollards are required for high-security or anti-ram applications
Selecting the wrong type can lead to poor performance or unnecessary cost.
- Ignoring ground conditions and services
Failing to check for underground utilities, drainage, or weak ground can lead to installation issues, additional costs, or safety risks. Ground conditions should always be assessed before installation begins. - Neglecting corrosion protection
Outdoor bollards are exposed to weather year-round. Choosing non-galvanised or poorly finished products can lead to early rust and failure. Hot-dip galvanising and optional powder coating significantly extend service life. - Overlooking visibility and safety
Bollards that are not clearly visible can lead to accidental collisions. Using bright colours (e.g. yellow), reflective bands, or contrasting finishes improves awareness, especially in low-light conditions. - Ignoring accessibility and compliance
Layouts must comply with UK accessibility guidance (e.g. BS 8300 and Equality Act requirements) to ensure safe passage for pedestrians, wheelchair users, and pushchairs. Poor placement can create barriers rather than solutions. - Under-specifying for the risk level
Using light-duty bollards in high-traffic or high-risk areas can result in damage or failure. Always match the bollard specification to the expected vehicle type, speed, and usage.
By addressing these factors early, you can ensure your bollard installation delivers reliable vehicle control, long-term performance, and full compliance.
At Aremco Barriers, we manufacture UK-made steel bollards designed for straightforward installation and durability. Whether for driveways, car parks, industrial sites, or public spaces, we can help you specify the right solution and avoid costly mistakes from the outset.
