  • Use Boroscopeand GPR to help determine overall void and cavity dimensions Utilize a 5/8” vinyl tube behind the block to guide the 24-003 To the problem location


  • The 24-003 polyurethane helped fill both the large and small voids, prevent future water and silt infiltration, and minimize weight added to the area
  • Two month installation with minimal disruption
