Asphalt Sealing

Prevent small cracks from becoming big problems with our crack sealing services!

Asphalt Crack Sealing

Asphalt crack sealing is among the most cost-effective ways for your business to extend the life of its parking lot. In most cases, it costs less than 10 percent of a complete asphalt replacement project. This process involves applying a hot sealant to cracks to keep water out.

Asphalt Crack Sealer

Asphalt crack sealer is used on working cracks. Working cracks are classified as such if they are greater than 0.1 inches. Working cracks are typically transverse cracks, although some longitudinal cracks may also be classified as working cracks. Working cracks are also classified as active cracks that continue to extend in size and severity with time, traffic, and weather.

These cracks are sealed with rubberized asphalt crack sealant. Rubberized sealant is watertight, flexible, and has excellent adhesive and cohesive properties, which allows it to bond to the sides of the crack and move with the asphalt as it contracts, expands, and shifts. This helps stop small cracks from becoming serious problems, and slows the development of potholes and large cracks.

When applying the asphalt crack sealant, our team ensures the substance completely fills the crack so no water or debris can get through. Just as important, they also take care to spot even the smallest cracks because they know exactly how quickly small cracks become dangerous, damaging potholes.

Types of Asphalt Cracks

There are a variety of different cracks that can occur in your asphalt lot. Our professional paving crews can ensure that all asphalt cracks are properly filled, sealed, and ready for use.

Alligator Cracking

Alligator cracks, also known as crocodile cracking or fatigue cracking, are a type of cracking that is caused by sealed pavement distress on your asphalt surface.

Slippage Cracks

Slippage cracks often form as a result of a weak asphalt mix. A poor blend of the asphalt sealant prevents a strong bond from forming between the pavement and the asphalt, resulting in long cracks forming.

Edge Cracks

Edge cracks form around or near the outer edges of your asphalt lot. These cracks are commonly caused by the lack of strength around the edge of your pavement.

Block Cracking

Block cracking is the result of an asphalt mix that was applied when it was too dry. These cracks develop squared shapes that are caused by temperature increases and decreases which expand and shrink the asphalt.

Longitudinal Cracking

Longitudinal cracking runs parallel to the asphalt surface’s centerline and is the result of poor longitudinal joint construction when the asphalt surface is initially placed.

Transverse Cracking

Transverse cracking runs perpendicular to the asphalt surface centerline. This type of asphalt cracking forms as a result of an improperly structured underlying layer of the asphalt.

Asphalt Filling

Asphalt is an incredibly durable material, used across millions of miles of highways, roads, parking lots, and driveways. That being said, it’s not indestructible, and eventually succumbs to the wear and tear of usage, weather and the passage of time. Cracks in asphalt are inevitable, but filling cracks when they’re still small has been proven to drastically slow the rate of cracking.

Asphalt Crack Filler

Asphalt crack filler is used in non-working cracks, which are less than 0.1 inches. Non-working cracks usually include longitudinal, diagonal, and some block cracks. Because filler is not flexible, it is only used in pavement that does not show significant movement. Filler does not completely keep water out of the crack, it simply reduces the amount of water and debris that gets into the crack.

Non-working cracks may not seem like a big deal and they can often go unnoticed. However, when water gets into the cracks and heats and cools as the temperatures change, those small cracks become big problems in just a matter of months. If left untreated, small cracks lead to tire-damaging potholes. Large cracks and buckled pavement become dangerous trip hazards for your customers and employees.

Most parking lots begin to display signs of asphalt failure two to three years after it has been installed because the proper maintenance has not been done to prevent cracks from occurring. Having filler applied before the cracks become a problem saves money by allowing you to stave off bigger repairs.
