Crack Filling: What is the Ideal Crack Filler for Driveway Cracks?

Asphalt crack filling is important to maintaining a safe and functional paved surface. Asphalt crack filling is the process of filling cracks in asphalt pavement. Cracks can form in asphalt for a variety of reasons, including wear and tear, tree roots, and extreme temperature changes. When left unrepaired, cracks can allow water to seep into the pavement, which can lead to potholes and other damage. Asphalt crack filling helps to prevent this damage by creating a seal that keeps water and debris out. The seal also helps to restrict the movement of air and water vapor, which can cause further deterioration of the asphalt.

If you have a crack-filling project, itā€™s important to understand that different types and materials can be used to fill your cracks. Some of these materials offer temporary relief, while others can last for years. With that said, letā€™s look at the two main methods of driveway crack filling.

What is Cold Applied Crack Filling?

Cold applied crack filling is filling cracks in the asphalt pavement using a cold fill material. The material is applied at ambient temperature and then cures to form a strong bond with the pavement. This method is usually used for small cracks and repairs. Cold-applied crack fillers are typically made from rubberized asphalt, which forms a flexible, waterproof seal that expands and contracts with the pavement as its temperature changes. Once the filler has been applied, it needs to be smoothed out with a squeegee or brush before it dries.

The main advantage of cold applied crack filling is that it does not require heat, which can be difficult to control on-site. In addition, cold-applied materials often have a longer shelf life than those that require heat for application. However, the downside to using cold-applied materials is that they tend to be more expensive than their hot-applied counterparts. As a result, they are typically only used for small repairs.

What is Hot Pour Crack Filling?

Hot pour crack filling is a type of asphalt repair used to fix cracks in roads, driveways, and parking lots. The process involves heating a liquid asphalt mix and pouring it into the crack filling machine. The machine then uses a wand to evenly distribute the asphalt over the affected area. Once the asphalt has cooled and set, it will create a barrier preventing water and other debris from entering the crack. While hot pour crack filling is not a permanent solution, it can extend the life of your pavement and prevent further damage.

Now, since you understand the two main types of crack filling, letā€™s look at the different types of crack fillers you can use on your driveway.

Coal tar crack filling

This is made up of a combination of refined coal, asphalt, and other chemicals that work together to fill cracks in asphalt and prevent water from penetrating the pavement. Coal tar crack filler is especially effective in hot, sunny climates where the pavement is exposed to a lot of ultraviolet radiation. The UV rays degrade the asphalt, making it more porous and susceptible to water damage. The coal tar helps to seal the pores and prevent water from seeping in. In addition, coal tar has a high level of adhesion, which helps it bond tightly with the asphalt. As a result, coal tar is an excellent choice for repairing cracks in asphalt pavements.

Asphalt-based crack filler

Asphalt-based crack filler is one of the most commonly used types. It is made from a mixture of asphalt emulsion, clay, sand, and other aggregate materials. Asphalt-based crack filler is easy to apply and is typically used for small to medium-sized cracks. Once it dries, it is black in color and very noticeable.

According to experts from CSG Sealcoating, Jacksonville, asphalt-based crack filler does not offer much flexibility, so it is best used on cracks that are not likely to expand or contract. This makes it less durable than other types of crack filler and will need to be reapplied more frequently. Nonetheless, the asphalt-based crack filler is a good choice for those on a budget or who do not need a long-lasting solution.

Epoxy and acrylic crack fillers

Epoxy and acrylic crack fillers are two of the most popular choices for filling cracks in concrete floors. Both have their advantages and disadvantages, so itā€™s important to choose the right type of filler for your needs. Epoxy crack fillers are strong and durable, making them ideal for high-traffic areas. However, they can be difficult to apply and require special equipment. Acrylic crack fillers are less expensive and easier to apply, but they donā€™t provide the same level of protection as epoxy fillers. For smaller cracks, an acrylic crack filler may be sufficient. But epoxy is usually the better choice for larger or more serious cracks.

Rubberized sealant

Rubberized sealant is one type of filler that can be used to repair cracks in asphalt. This sealant is designed to flex and move with the pavement, making it less likely to crack or break over time. In addition, the rubberized sealant forms a water-resistant barrier that helps to prevent moisture from causing further damage to the pavement. However, rubberized sealant can be more difficult to apply than other types of fillers, and it may not be compatible with all types of asphalt. As a result, it is important to consult with a professional before using this type of sealant on your pavement.
