Joint & Crack Sealing

What it is:

Joint & Crack Sealing is the first step in preventative maintenance for asphalt pavement surfaces. Sealing extends the life of the pavement by reducing water intrusion, which will prevent and slow down secondary cracking and spalling. Spalling is a pop out or hole that forms around a crack or joint. Crack Sealing is a more expensive maintenance than Crack Filling but provides substantial value due to its long life expectancy. However, if the surface is badly back-cracked or map-cracked, it is likely going to need our clean and fill service instead. Joint & Crack Sealing will provide the most benefit when reflection cracking (moderate surface cracking) is visible, but before faulting and spalling beings.
