Sealcoat removal contractors

To protect human health, the environment, or property values, or to help alternative sealcoats or overlays of other materials adhere better, public agencies and private property owners may decide to remove coal tar-based sealant previously applied to a paved surface.

This page provides information on safe removal of sealcoats and top layers from asphalt pavement. This removal is typically done by grinding or shotblasting. Removal is not recommended for asphalt in poor condition or with significant cracking, since the blasting or grinding process may break such pavement into pieces. 

Along with other jurisdictions in the Upper Midwest, Great Lakes region, and around the U.S., Minnesota now prohibits the use of coal tar sealants on asphalt surfaces such as driveways, parking lots, and school yards. 

However, this web page should not be construed as requiring or advising pavement owners or regulators to choose to remove coal tar sealcoats: the decision is theirs alone.

Coal tar-based sealants may release harmful contaminants called polycyclic aromatic hydrocarbons (PAHs) into surrounding air and soil, or into lakes, rivers, streams, and sediments.

Therefore, safe removal of sealants or top layers should include enclosing the grinding or blasting process, vacuum-collection of the debris (with HEPA filtration of the exhaust), and containing it for disposal. This includes providing the employees doing the removal the proper hearing, respiratory, and skin protection. Even with high-efficiency containment and collection, this is a necessary precaution given the PAHs and other hazards in coal tar and in asphalt dust.

Property owners should ensure that their contractor is properly licensed and bonded and will use proper removal and disposal methods. Contacting neighboring property owners in advance is also encouraged so they may close windows and air intakes and take additional precautions to reduce exposure.

Coal tar sealcoat and other removal debris should be disposed of properly. No matter the location, pavement owners and contractors must be aware of and comply with applicable local, state or provincial requirements for requirements for management and disposal. For example, in Minnesota, coal tar sealcoat removal debris should be disposed of in a solid waste landfill, with the approval of the landfill operator.

Removal costs around the U.S. have ranged from $0.60 per square foot for larger surfaces to $1.25 per square foot for small areas. However, experience is limited so there may be significant variation.
