Bollard repairs

What is it?

What are bollard repairs?

Bollard repair is the work needed to return a damaged or failing bollard to safe, working condition without replacing it entirely. Typical repairs include re-bedding a loose or leaning post, re-fixing a base plate with new anchors, replacing a seized socket, lock, cap or hinge, clearing a blocked cassette and renewing reflective bands. Repairs are carried out as paid visits, priced in writing before any work starts.

Bollards take knocks, weather and daily use, and they rarely fail all at once. A post starts to lean after a car nudges it, a removable bollard's lock seizes, a telescopic post fills with silt and refuses to lower, a fold-down post's hinge bends. Left alone, each of these becomes a trip hazard, a security gap or a post that nobody can use. Most can be put right without replacing the bollard.

Repairs are paid visits. We ask for photographs and a description first, then give you a written price for the visit and the likely work before anyone attends. If something different is found on site, we tell you and price it in writing before carrying it out. The work is done by installation crews working under our management.

When posts need repairing

• Posts leaning or rocking after a vehicle knock
• Base-plated bollards with loose or sheared anchors
• Removable bollards with seized locks or damaged sockets
• Telescopic posts that will not lower or lock
• Fold-down posts with bent hinges or broken locks
• Missing caps, worn paint and faded reflective bands
• Lost keys and mismatched locks across a site

How it works

Every repair starts with finding the cause rather than the symptom. A leaning post usually means the foundation has cracked or moved, not that the post itself is bent; straightening the post without fixing the base just means it leans again. A base plate that keeps loosening usually means the anchors were set in weak concrete, too close to an edge or in a crack, so new anchors go in fresh positions or the slab is repaired first.

Re-bedding means breaking out the old foundation around the post, setting the same post plumb in new concrete and reinstating the surface. Sockets for removable bollards that have seized or been crushed are cut out and replaced. Locks, keys, caps, hinges and reflective bands can usually be renewed on site. Telescopic and semi-automatic cassettes are emptied, cleaned and their drainage checked, because a blocked drain is behind most stiff or seized posts.

Some damage is not worth repairing. Steel that has been bent sharply is weakened, and a post with a crease or torn wall should be replaced rather than straightened. Crash-rated bollards are a separate case: after an impact they should be assessed with the manufacturer and are usually replaced to the tested detail rather than repaired.

How we do it

Ground, foundations and buried services

Many repairs are really foundation repairs. Re-bedding a post means breaking out old concrete, which may be larger or deeper than expected, and checking for services before digging further. Base-plate repairs depend on the slab: if the concrete has cracked or crumbled around the anchors, it is cut back and repaired before new fixings go in. Sockets and cassettes are reset to the exact finished surface level, with drainage restored beneath. Reinstatement matches what is there, whether tarmac, block paving, flags, resin or turf, though older or weathered surfaces may show a visible patch.

Rules and checks before you order

• Make damaged posts safe promptly, as a leaning post or open socket on a footway is a trip hazard.
• Do not repair crash-rated bollards in ways that change the tested product; involve the manufacturer.
• Check whether the bollard is on public highway or council land; the highway authority may need to authorise work or carry it out.
• On heritage bollards in conservation areas, repair and reset rather than replace where the conservation officer expects it.

See rules and standards by nation for highway consent, accessibility and security standards.

Maintenance

Most repair call-outs come from small problems left too long. Lubricating locks a few times a year, lifting removable and telescopic posts periodically, keeping cassettes clear of grit, touching up chipped paint and checking for lean after knocks will prevent many of them. Keep a record of bollard types, suppliers, key numbers and colours on site, so a repair can be quoted and matched quickly when it is needed.

What affects the price

• Type of repair and number of posts
• Whether foundations or slabs need breaking out
• Availability of matching parts, locks and caps
• Surface type and reinstatement
• Access, traffic management and working hours
• Making safe before the main repair
