  elastomeric concrete header applications, while allowing
  multidirectional movements of the structure.
• Unique Design
  Designed to provide a watertight seal and minimize
  debris, the Wabo Silicone Seal will easily bond to itself.
  No priming of interfaces is required which simplifies and
  accelerates the installation process.
