The American Concrete Institute (ACI) established the Shotcrete Nozzleman certification program to establish a basic skill level for shotcrete placement. A design engineer or specifier should always require an experienced and qualified contractor for support, which includes experienced crew members and the proper equipment including material selection for the specific project. This gives the specifier assurance that the entire shotcrete team (qualified contractor, ACI certified nozzleman, and experienced crew) have proven their knowledge and ability to consistently place quality shotcrete.

Although the certification and certificates are issued by ACI, education and testing are provided by Sponsoring Groups authorized by ACI. The American Shotcrete Association (ASA) is the primary sponsoring group consisting of ACI Approved Examiners for the Shotcrete Nozzleman certification program.

Listed below are informational items designed to explain the certification process, costs, required forms, and proper use of certification by owners and specifiers.

If you have any questions on the coordination of a new certification and or education session please contact ASA staff at 248.963.0210 or [email protected].

ASA note regarding Nozzleman certification

Hiring a shotcrete contractor solely because he employs a certified nozzleman is short-sighted and irresponsible. Make sure the contractor and his team is well qualified and experienced with your type of project. Due diligence and proper use of nozzleman certification, as outlined below in the “Certification User’s Manual,” could be the difference between the failure and success of a project. The extra work upfront will pay off exponentially as the speed, quality, versatility, and economic advantages of shotcrete are fully realized.
