How to Spot Structural Cracks in Commercial Lots
Identifying structural cracks early in commercial parking lots can save property owners significant repair costs and maintain safety standards. This guide will help you recognize the most common types of cracks and understand their implications.

Understanding Structural Cracks
Structural cracks in commercial lots are more than just surface blemishes. They often indicate deeper issues related to the foundation or paving materials. Recognizing these cracks early ensures timely intervention, which is crucial for maintaining the integrity of the lot.
Common Types of Structural Cracks
1. Fatigue Cracks
Also known as alligator cracking, fatigue cracks resemble a reptile’s skin pattern and usually appear due to repeated traffic stress.
2. Longitudinal Cracks
These cracks run parallel to the pavement’s centerline and are often caused by poor joint construction or material failure.
3. Transverse Cracks
Running perpendicular to the lot’s length, transverse cracks typically result from temperature changes causing expansion and contraction.
4. Settlement Cracks
Settlement cracks occur when the soil beneath the lot shifts or compacts unevenly, causing the surface to crack.

- Visual Inspection: Walk the entire lot looking for irregular crack patterns, paying special attention to high-traffic zones.
- Measure Crack Width: Use a ruler or crack gauge to assess the width; cracks wider than 1/4 inch usually need professional attention.
