granite seal treatment as it appears on a city street

Public Information Office – May 20, 2019

In the next few weeks, construction crews will begin a repair process throughout City streets known as granite seal. The procedure is cheaper than mill and overlay, which involves scraping away part of the damaged street and overlaying with new material.

The process involves:

Pouring an emulsion and adding loose granite material over the street.
Within 4 to 8 hours, crews will sweep over the street to remove some of the loose material.
In 72 hours, crews will sweep it again to pick up additional loose material.
A third sweep will be done to clean up remaining material.

During this procedure, it is possible that there will be loose gravel on City streets. Caution is advised, as well as following posted speed limits.
