Contract crews to repair City streets with granite seal process

 City of Leavenworth Public Information Office – May 15, 2017

Beginning in June, 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.

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. See attached image for areas that will undergo granite seal repair.
