Protect your Investment.
Hot Joint Crack repair is one of the best ways to get the most out of your roadway or parking lot.
Crack filling is one of the most important parts of asphalt maintenance. Parking lots and roadways frequently need cracks filled, especially in Michigan because of the intense freeze/thaw cycle. This simple step can help extend the lifetime of your asphalt and prevent potholes from appearing.
FAQs
-
Hot joint crack repair is used primarily for roadways, parking lots, and other high traffic areas. We often service property managers, Home Owners Associations, and local businesses to try and give them the most value out of their asphalt. If you are a residential customer, it is most likely that cold joint sealant will be applied to your project area. Hot joint crack repair does not sit flat and is not ideal for driveway aesthetics and is less functional for snow removal in residential. Alligated or ‘spider-webbed’ asphalt is not a good candidate for hot rubber crack repair as there is not enough surface area for the crack repair to bind to.
-
Hot joint crack repair is done by first cleaning the area of any debris with compressed air. While the area is being cleaned, our CPMG Magma1 hot joint crack repair machine heats rubberized crack sealant. Once the area is cleaned and the machine is properly heated, one skilled laborer will use the pressurized, heated gun to apply the rubberized crack filler to any cracks to then be squeegeed by one to two other laborers. It is typically applied to cracks 1/4” or larger with a banding width of 3”.

Michigan’s cold weather is especially tough on asphalt, and it is recommended that you get your cracks filled annually. It is best however, to treat cracks as soon as possible, as the more water that reaches the subbase, the greater chance more damage to the asphalt will appear.
-
Hot joint crack filler has a faster cure time than other asphalt products such as sealcoat and can typically be driven on within minutes of it being applied. Temperatures and precipitation are a major factor, meaning the substrate and air temperatures must be 40ºF or above.

Hot joint crack sealant helps increase the longevity of your asphalt by preventing further water erosion, subbase deterioration, and the damages that occur during a deep freeze. By sealing off any open cracks, this helps prevent water from penetrating the subbase, which is one of the main causes of asphalt failure. This helps lower the cost of maintenance over the long term as less cracks and potholes are likely to appear. It also helps with the overall aesthetic of any neighborhood roadway or business parking lot.
