Winter is tough on Missouri parking lots. Between the snow, ice, freezing temperatures, and deicing chemicals, your pavement takes a beating from November through March. Now that warmer weather has arrived, spring is the perfect time to assess the damage and plan repairs before small problems turn into expensive headaches.
Start With a Visual Walkthrough
Before diving into specifics, take a slow walk around your entire parking lot. Morning light often reveals surface irregularities that are harder to spot at midday. Bring a notepad or use your phone to document problem areas with photos and notes.
Pay attention to how the lot feels underfoot. Soft or spongy areas may indicate subsurface damage that is not yet visible on the surface.
Check for Cracks
Cracks are the number one thing to look for during your spring inspection. Winter's freeze-thaw cycles are particularly hard on existing cracks because water seeps in, freezes, expands, and forces the crack wider with each cycle.
Look for these common crack types:
Linear cracks run in straight lines and often indicate stress from traffic patterns or underlying movement.
Alligator cracking resembles reptile skin with interconnected cracks forming irregular patterns. This suggests structural failure and requires more than surface repairs.
Edge cracks form along the perimeter where pavement meets curbs or grass. Poor drainage often causes these.
Document the location, length, and width of all cracks. Cracks wider than a quarter inch need immediate attention before spring rains make the damage worse.
Inspect for Potholes
Potholes are the most obvious sign of winter damage and the most urgent to repair. They form when water penetrates the pavement, freezes and expands, then thaws and leaves a void. Traffic passing over the weakened area causes the surface to collapse.
Note the size, depth, and location of each pothole. Even small potholes grow quickly once spring rains begin, and they create liability concerns if customers or employees trip or damage their vehicles.
Look for Drainage Issues
After a rain, walk your lot and note any areas where water pools or drains slowly. Standing water accelerates pavement deterioration and will cause serious problems when next winter arrives.
Check these common trouble spots: low spots where pavement has settled, clogged drains with debris and salt residue, damaged catch basins, and areas near downspouts where runoff may be eroding the pavement edge.
Assess Surface Condition
Beyond cracks and potholes, evaluate the overall condition of your pavement surface:
Raveling occurs when aggregate starts separating from the asphalt binder, leaving a rough, gravelly surface. This indicates the sealcoat has worn away.
Fading from deep black to gray or brown suggests UV damage and aging.
Rutting appears as depressions in wheel paths and indicates the base layer may be failing.
Examine Curbs and Edges
Snow plows and ice often damage curbs, especially at corners and entry points. Check for chipped or broken sections, curbs that have shifted, and damaged wheel stops. Also examine where asphalt meets grass or buildings for erosion or separation.
Evaluate Striping and Signage
Winter weather, snow plows, and salt take a toll on painted markings. Check all parking space lines, handicap spaces and access aisles, fire lanes, directional arrows, crosswalks, and speed bumps. If markings are significantly faded, spring is ideal for restriping.
Verify that all signs are upright, visible, legible, and compliant with ADA requirements. Missing or damaged signage creates liability exposure.
Create Your Repair Priority List
After completing your inspection, organize your findings:
Immediate repairs include potholes, trip hazards, and any damage creating safety concerns. Address these within days.
Short-term repairs include crack sealing, minor patching, and drainage corrections. Schedule these for early spring.
Seasonal maintenance includes sealcoating and restriping. Plan these for late spring when conditions are ideal.
Frequently Asked Questions
How soon after winter should I inspect my parking lot?
Complete your inspection once temperatures consistently stay above freezing and snow has melted. In Southwest Missouri, this typically means late March or early April.
Can I do the inspection myself?
Property managers can perform a basic visual inspection using this checklist. For larger lots or significant damage like alligator cracking, a professional assessment helps determine whether repairs or reconstruction is needed.
What repairs should be done first?
Safety issues always come first. Potholes and trip hazards should be addressed immediately, followed by crack sealing to prevent water infiltration.
Is spring the best time for sealcoating?
Spring can be excellent for sealcoating once temperatures consistently reach 50 degrees or higher and no rain is forecast for 24 to 48 hours.
How often should I inspect my parking lot?
A comprehensive inspection should be done at least twice per year, in spring after winter and in fall before winter arrives.
Schedule Your Professional Assessment
A spring inspection is your opportunity to get ahead of problems before they escalate. Small cracks become potholes. Potholes become safety hazards. Deferred maintenance becomes expensive reconstruction.
