Our process
There are many different methods of crack sealing asphalt, but they are not all created equal. A routed, hot-pour crack sealing treatment will last much longer than your standard cold-pour (high flow), non-routed crack sealing job.
GreenSeal offers the most durable, long-lasting, and high-quality method of crack sealing available, which meets the highest specifications. How do we do it?
ROUTING
We use an industrial router to increase the volume of the void of the crack or joint, which creates a wide tough in which to pour the sealant. This process ensures an increased and uniform surface area on the vertical walls of the crack or joint, and provides a superior surface area onto which the sealant material will bond.
CLEANING
After the routing is completed, we use a large industrial vacuum so the routed cracks or joints are completely dry and free of sand, dust or other foreign debris. The vacuum collects any road dust, ensuring that is it not blown all over your property.
THREE-PASS APPLICATION
We apply three passes of hot-poured, rubberized material (ASTM 211) sealant over the joint or crack surface, making sure that the material is evenly applied, and flush with the adjacent pavement or be feathered to prevent damage by snow plows.
Why seal cracks?
Crack sealing is a cost-effective way to extend the life of your road surfaces and prevent costly future repairs or early replacement. A quality routed, crack sealing job will prevent small cracks from turning into potholes, and undermining your asphalt.
As cracks develop in asphalt, the surface becomes permeable to water, weather, and weeds. All of these can deteriorate the underlying road base, developing into potholes, and compromise your asphalt. Don’t wait until you have to resurface. Sealing cracks now will prevent damage, and will also prevent more cracks from forming.
What causes cracks?
WATER
When it rains, water enters cracked asphalt and washes away the engineered road base beneath it. This reduces the structural support that maintains its strength and integrity. A compromised road base will eventually result in potholes or damaged asphalt.
WEATHER
When water in your road base freezes, the expanding ice puts pressure on the asphalt by heaving it upwards, damaging the asphalt further.
WEEDS
Grass, plants, and weeds can grow up through the cracked asphalt. Root masses undermine and break up the asphalt causing new cracks where water will enter, and seeds will take root.
