  • National Gunite is experienced in repairing all shapes and sizes of deteriorating brick, corrugated metal pipe and concrete manholes.
  • Due to the limitations of their equipment, most manhole rehabilitation companies can work a maximum distance of about 200 feet away from the street. National Gunite’s specialized equipment gives us the ability to work virtually anywhere.
  • In addition to using gunite, we are certified applicators of the following other repair systems if an alternative is indicated:

    Kerneos SewperCoat 2000HS
    Kerneos SewperCoat 2000PG
    Parsons Environmental Products
    Strong-Seal MS-2 Systems
