Top-Seal Black forms a layered coating over the road base that rapidly transforms into a hardened, independent surface. It also increases surface friction, thereby shortening braking distance.

Top-Seal Black is calculated at a rate of approximately 0.15 gal/sq yd (0.5L/m2). After it has been applied and has hardened (polymerized), it creates a thick membrane coating, which prevents the penetration of water and air into the pavement.

Top-Seal Black is a polymer-based emulsion that requires water dilution. It is non-petroleum-based and eco-friendly, evaporating only water during the curing process and emitting no volatile organic compounds (VOCs). It does not contain solvents or cause damage to roads or vehicles. It is easily applied, requiring no special equipment or handling procedures. Top-Seal Black is patented by the University of Texas at Austin and licensed exclusively to Terra Pave International, Inc.

Top-Seal Black creates a durable wearing surface over soil bases for roadways, parking lots, and airfields. As an alternative to asphalt, Top-Seal Black:

  • Enhances surface friction
  • Improves commuter safety
  • Increases load-carrying capacity
  • Prevents water penetration
