More than 30 percent of urban kerb sections show visible damage. Damaged kerbs create trip hazards for pedestrians and cause tyre and wheel damage for vehicles. This guide covers what causes kerb damage and how to catch a chipped section before it becomes a full kerb-and-channel replacement.
What Is Inside
- How a kerb is built, from foundation to face, and where damage starts
- The 120 million dollar annual repair and liability cost
- How AI classifies four kerb defect types automatically
- A severity matrix by chip depth and displacement
What Causes It
- Vehicle impact from mounting or scraping the kerb while parking or turning
- Freeze-thaw and weathering cracking and spalling concrete kerbstones
- Tree root intrusion lifting and displacing sections over time
- Poor construction joints separating under repeated load
How AI Finds It
- Collect: dashcam on any vehicle or phone, GPS-tagged, no road closures
- Detect: chipped, cracked, displaced or missing sections found automatically
- Locate: exact GPS and chainage per section, with a damage photo attached
- Deliver: GIS dashboard, priority list and cost estimates within hours
Severity and What To Do
- Low, under 20 mm chip with the kerb line intact: routine monitoring
- Medium, 20 to 50 mm chip or 10 to 20 mm shift: schedule spot repair within 60 days
- High, over 50 mm chip or 20 to 50 mm shift: section replacement within 14 days
- Critical, missing kerbstones with the edge structurally exposed: emergency replacement
Who It Is For
- Municipal bodies and urban road authorities
- Footpath and pedestrian safety teams
- Maintenance contractors
A chipped kerb section costs a fraction of the full-length kerb-and-channel replacement it becomes.
