A BST Overlay, or Bituminous Surface Treatment (Commonly called top coating) is a method of repaving that doesn’t require the complete removal of the old paving. BST overlay is laid down on top of existing pavement sealing cracks, and imperfections. This prevents the underlying asphalt and road base from further deteriorating. This method of repaving, when done right, preserves the life of the asphalt for many years to come. Furthermore the total cost of a BST overlay is far less than fully repaving.
Before any job, our experienced team performs an inspection of the property where work has been requested. If the issues with the subgrade or drainage would cause premature failure in the overlay we will discuss other potential paving options.
