PROJECT

  • Many of their manholes are brick and have been in service for a long time.
  • There was concern that the extreme corrosion of the mortar might cause the manhole to collapse if the lid was dropped back into place.

SOLUTION

  • The project involved the spin cast rehabilitation of 15 manholes with calcium aluminate.
  • Additionally, 4 of the 15 were to be lined with the Ameron Arrow-Lock Lining System. These 4 had an extremely abrasive, corrosive environment.

RESULTS

  • The application was completed in 2008 and has provided exceptional protection since then.
