Potholes don't appear overnight. Understanding their formation helps property managers prevent them through timely maintenance.
Parking Lot Maintenance Overview
Potholes begin as small cracks. Water enters cracks, freezes, expands, and widens the crack. Vehicle loads flex the weakened pavement, dislodging chunks of asphalt. What started as a hairline crack becomes a pothole in one winter.
Crack sealing is the most cost-effective pothole prevention measure available. Routing and sealing pavement cracks at the first sign of formation costs roughly $1-2 per linear metre — orders of magnitude less than pothole repair.
Why Regular Maintenance Matters
Timing crack sealing correctly maximizes effectiveness. Cracks should be sealed when they're 3-13mm wide, clean, and dry. Cracks that have already admitted significant water may have compromised base course beneath — sealing the surface without addressing the base provides limited benefit.
Edge deterioration prevention is also important. Pavement edges without proper containment — curbs, edging, or adequate base — deteriorate rapidly as edge material cracks and displaces. Maintaining edge condition prevents cascade deterioration inward.

Drainage maintenance reduces pothole formation. Addressing areas where water pools ensures the base course isn't chronically saturated. A well-drained pavement is significantly more resistant to freeze-thaw damage.
The maintenance cycle that prevents potholes: inspect annually, seal cracks promptly, reseal the surface on schedule, maintain drainage infrastructure, and address edge conditions before they deteriorate.
Property managers who implement preventive pavement programs typically spend 30-50% less on pavement maintenance over a 20-year period than those who defer maintenance and respond reactively to failures.
