Cracks in a parking lot may not seem like a big deal at first, but they can quickly turn into serious problems. Knowing when it’s time to seal a crack and when it’s too large to seal is critical to protecting your asphalt investment. This is where understanding parking lot crack repair thresholds becomes essential. At Asphalt Contractors, we specialize in assessing cracks and providing effective repair solutions across Southeast Wisconsin.

Keeping your asphalt surface in good condition starts with regular inspections. Cracks let water seep underneath the pavement, causing erosion and leading to potholes or structural damage. Thankfully, sealing small to medium-sized cracks can stop this damage before it spreads. But not every crack can be fixed with sealant. So, how do you know what size crack is too big to seal?

Understanding why cracks form in the first place helps in knowing how to fix them. Asphalt expands and contracts with temperature changes. Over time, this causes stress on the pavement, leading to cracks. Common causes include:

– Weather and temperature extremes

– Poor initial installation

– Inadequate drainage

– Heavy traffic loads

– Aging asphalt

Whatever the reason, once a crack forms, it needs attention. The size and behavior of the crack determine whether crack sealing is the best solution or if more serious resurfacing or patching is needed. At Asphalt Contractors, we use expert assessments to determine the right fix.

Parking lot crack repair thresholds refer to the size, shape, and type of cracks that determine whether sealing is a suitable option. There’s a big difference between a tiny surface crack and a wide fissure that’s deep in the asphalt. When identifying the right technique, contractors look at a few key factors.

Width of the Crack

Crack width is the most obvious factor. Generally, cracks under 1/2 inch wide are considered sealable. They may have started small and expanded slightly over time but have not yet caused structural failure.

– Cracks less than 1/4 inch: Often cosmetic or surface-level, easily sealed

– Cracks between 1/4 inch and 1/2 inch: Moderate concerns, ideal for sealing

– Cracks wider than 1/2 inch: Usually too large to seal and may require patching or more intensive repair

If your parking lot has multiple large cracks over 1/2 inch wide, it’s a sign that simple sealing won’t be enough. In these cases, Asphalt Contractors recommends a thorough inspection to evaluate whether patchwork or resurfacing is needed.

Depth of the Crack

Even if a crack isn’t extremely wide, deep cracks can extend into the base layers of your asphalt. These types of cracks may allow water, salt, and debris to penetrate under the surface, weakening the foundation. Cracks that penetrate through more than 1 inch of asphalt indicate foundational stresses. Surface sealants won’t be able to stop the spread, and more robust solutions like filling, patching, or milling might be required. Asphalt Contractors has the equipment and expertise to handle deep and complex crack repairs efficiently.

Type of Crack

The type of crack can often tell you how severe the damage is and whether sealing is the right solution.

– Linear Cracks (transverse or longitudinal): Often caused by temperature or age, these are usually sealable if under the width threshold

– Block Cracks: Pattern-like cracks that indicate aging pavement—often sealable when small, but may indicate deeper issues

– Alligator Cracks: Resemble the skin of an alligator and indicate structural failure—not sealable; needs patching or replacement

Alligator cracking is one of the most serious signs of pavement stress. If your lot has these types of cracks, sealing won’t help. Asphalt Contractors can assess this damage and recommend a durable long-term fix.

Sealing is one of the most cost-effective forms of asphalt maintenance when performed at the right time. It’s ideal for new or relatively minor cracks and helps extend the lifespan of your pavement. Here’s when sealing is the smart choice:

– Cracks are less than 1/2 inch wide

– Surface is in otherwise good condition

– No deep penetrating cracks or base damage

– No standing water or drainage issues

The sooner you seal developing cracks, the better your chances of avoiding high-cost repairs later. Asphalt Contractors uses high-quality materials and professional-grade sealing equipment to ensure a lasting finish across all our Southeast Wisconsin service areas.

If cracks exceed the parking lot crack repair thresholds, other methods will be necessary. Ignoring large cracks or trying to seal them anyway can lead to rapid deterioration of the pavement and potentially create safety hazards for drivers and pedestrians.

Crack sealing may not be sufficient when:

– Cracks are wider than 1/2 inch

– Cracks show signs of base erosion or movement

– Alligator cracking is present

– Cracks continue to grow rapidly despite regular maintenance

In these cases, Asphalt Contractors offers solutions such as crack filling, full-depth patching, asphalt overlays, and milling. These advanced services help correct deeper problems and restore your parking lot’s integrity
