Black Diamond is GemSeal's new, high performance alternative to asphalt emulsion (AE) sealer and refined tar sealer. With all the environmental benefits of AE sealer, Black Diamond exceeds AE performance with longer durability, increased toughness against power steering marks, and stays black. Black Diamond also provides performance similar to refined tar sealer's fuel resistance, durability, and ease of application.

Properly maintained parking lots will comply with the codes set forth in the Americans with Disabilities Act (ADA). You can also expect clearly marked parking stalls that will allow traffic to flow smoothly. With pedestrian pathways to and from the building entrance, all of your customers will be safe and secure.

A scheduled program of pavement maintenance that includes sealcoating and crack filling will more than double the life cycle of your asphalt pavement and provide maximum curb appeal. Sealcoating and crack filling is a fraction of the cost of repairing or replacing asphalt pavement. Crack Sealing Provides Superior Protection Against Moisture Intrusion - The Leading Cause of Pavement Failure.

Moisture intrusion is the leading cause of pavement deterioration. When left alone and when cracks are not repaired, potholes become evident and a safety problem. Potholes represent an annoyance to vehicle traffic and a serious tripping hazard to pedestrians. To Properly Maintain a Driveway or Parking Lot, It's Important to Prepare the Asphalt Surface Prior to Sealcoating.

Dust control is important in all types of sitework and earthwork to mitigate dust being generated by related activities on the site, and help keep dust from leaving the site perimeter.
