All you need to know about a Crack Fill Machine

crack fill machine

The pavements covering millions of miles are made using asphalt concrete material. The only problem using this material is the perilous cracks for the sustainability of the roads. It becomes necessary to repair these pavements from time to time, and using a crack fill machine is the best way to do it.

Filling cracks mainly prevent water from getting down into the underneath layers of asphalt, causing potholes and distortion. Crack fill machines work with hot rubberized and cold liquid crack filling techniques to get the job done quickly. The machine is straightforward to use. It is more like a lawnmower and even cheap in price. There might be some cracks that need rutting before they get sealed. The route channels widely open the space, improving sealing performance and providing smooth and uniform walls to let the sealant settle in. The other equipment required to fill up the cracks includes pour pots, melters, and cleaning machines.

It is wise to repair the cracks using these machines while there is still time to save the pavement from a complete breakdown. Replacement of the whole surface will cost many times more than crack filling.

There are some doubts needed to be cleared before using the machine.

Choosing the best Crack Filler Machine

If you’re planning to buy a crack fill machine for personal or commercial use, then you need to know which one is the best option for you. To fill the crack in the right way, you need to follow a few things.

The first will be cleaning out the cracks and all the dirt and debris to ensure the clean sidewalls of the gaps. You can do it with a wire brush or a scraper too.

Secondly, you have to keep in mind what type of crack fill machine you choose to get the job done. The two best ones are mentioned below.

Cold pour filler: An acrylic water-based crack filler that comes with a 5-gallon pail to be applied with hands using a U-shaped or a V-shaped squeegee to make the cracks smooth. These types of fillers are generally used in the residential market and are best for the homeowners because of their low price and less efficiency in doing a commercial job.

Hot pour filler: These are more useful for professionals and contractors as the fillers use a hot rubber-based adhesive, ensuring that the cracks filled are more substantial. The hot pour melter applicator does its job real quick in a way just like a lawnmower moves.

Why to use it?

It is a very simple and straightforward answer that repairing cracks just as they appear is the only option to save the pavement from a complete replacement. The use of a crack filler machine is quite helpful because:

Saves Money: The money spent on a crack filler machine is a one-time investment that is smart to make, considering the high cost of replacing the surface altogether. It saves a considerable amount of money and other resources. You can even make money using these crack fillers by using it to repair cracks as professionals.

Extends life of pavements: As the cracks are filled as good as they were not even there, the life of these pavements extends by a few more years. Although it might need some repairing from time to time, the cost for those repairs will still be less than replacing the pavements.

Easy to use: These are shopping cart-like machines which are very easy to carry, and no special training is required to learn how to use them. Just clean out the cracks and set up your machine to get going like you are gardening on your lawn.

Prevents oxidization: The main motive of filling these cracks is to prevent the water from going inside the pavement’s surface through those cracks. Water will cause severe damage and will lead to eventually replacing the whole area. Due to this, these cracks are potholes that should be filled as soon as they appear.

How to use it?

The crack fill machines are pretty easy to use. That being said, there are still a few tips that you should keep in mind to use the machines at their total capacity.

Control machine’s temperature: You must know when to turn the regulator off while using the machine and melting the rubber. At 350 degrees F, the rubber blocks are completely melted.

Learn a proper way: Using the right gear like boots and gloves, which side will you load it from. Learning all this is necessary for appropriately using the machine.

Limit the material: Always keep in mind that the machine is not overfilled to avoid wastage. Limiting the crack fill on the surface is a good option.

Use a tiger torch: You need to use a tiger torch to clean your machine to heat up the valving system, and a squeegee can be used to spread out puddles.

Conga line: It is the most efficient way to fill cracks. A crack cleaning person cleans out the debris and vegetation, then a blower man blowing the dirt, and finally, the crack melter fills the cracks completing the process.


If the cracks that destroy the pavements to such an extent that it eventually needs to be replaced can be repaired using a simple process, it is no less than a lifesaver. Discussing the types, advantages, and tips to use ends with everything you want to know about the crack filling machines.
