Coal tar ban

Coal tar has long been used as a preferred seal coating for roads, parking lots and driveways. Recent studies found by the United States Geological Survey have called for a ban of coal tar sealants in some towns in Chicago. Be aware of your available options by hiring a professional sealcoating company.

Our Solution

Mike's Sealcoating offers Gem-Seal Black Diamond pavement sealer, a highly feasible alternative to coal tar based sealant. In case your area comes under coal tar pavement sealant ban, you can now opt for the Gem Seal sealer, which provides the same benefits and gives long lasting life to asphalt surfaces.

Your Advantage

Whether the tar ban is in effect in your part of town, we offer you both coal tar as well as black diamond sealant options. We leave it entirely at your discretion to choose any of these for your asphalt project. For communities that have the ban in place, you can still gain all the advantages of a sturdy asphalt based surface with Gem Seal Black Diamond pavement sealer.
