What does chip sealing do?
Chip seals enhance safety by providing good skid resistance. Chip seals provide an effective moisture barrier for the underlying pavement against water intrusion by sealing cracks in the pavement. Chip seals prevent deterioration of the asphalt surface from the effects of aging and oxidation due to water and sun.
How often do you chip seal?
Typically, a chip seal surface requires a new sealing on top of the existing one every 7-10 years. In order to get more life out of each seal application, avoid using heavy machinery like snowplows or vehicles with studded tires.

Is chip seal permeable?
The chip seal is likely to prevent infiltration of water from above into the pavement system below except through the reflection cracks after a year or so. Properly designed HMA courses are generally permeable to moisture vapor allowing it to escape but almost impermeable to free water.
What is the difference between chip seal and seal coat?
To put it briefly, chip seal is an alternative to asphalt, while slurry seal is a method of repairing asphalt, while seal coating is a protective process for your asphalt. They may sound similar, but each has its own purpose and place in the world of pavement.
