The ASA was and is largely a collective effort. I am very proud of our organization and of all that we have achieved in roughly a 25-year span of time.
An Intersection of Art and Engineering in Shotcrete
Rosado-Seijo and Kwade’s sculptures stand as a testament to the power of collaboration between artists and shotcrete specialists, exemplifying the possibilities that arise when creative artistic vision meets shotcrete’s technical capability.
The Diversity of Shotcrete
It is truly paramount to recognize the diversity of solutions available because of the versatility that shotcrete offers. Shotcrete placement provided more efficient, sustainable and durable concrete solutions in these two cases than could have been achieved with a form-and-pour approach.
Relieving Water Pressure on Shotcrete Lining by Integrating a Drainage Mesh
Underground construction, especially a tunnel, is one of the most complex challenges in the field of civil engineering. Dolenco Drain is an innovative solution which addresses many of the difficulties with controlling or eliminating water pressure in an easy, safe, long-term, and cost-effective manner.
Early Age Strength Testing for Shotcrete: 2024
For improved safety in tunneling and mining projects that use shotcrete for ground support, early shotcrete strength should be evaluated by testing. Based on their range of effectiveness, two procedures stand out: The new Hilti BX 3-SCT stud driving method and the beam end tester.
Geohazard Mitigation: Why Shotcrete?
To improve safety and mitigate the risks of rockfall events along I-65 in Giles County, TN, GeoStabilization partnered with the Tennessee Department of Transportation and a local construction company.
Rapid Strength Gain Dry-Mix Shotcrete: A Unique Solution for Highly Complex Projects
The construction industry must embrace new technologies and innovations to address today’s challenges. With its unique features, shotcrete stands out as a placement solution, meeting the most stringent project standards and offering unmatched benefits compared to traditional form-and-pour concrete.
Pre-Job Safety Checks
A well-planned job with a focus on safety will bring profit to your company, and your customers will appreciate a job done on-time and on-budget. Spending the proper time every day pre-planning and ensuring the job is safe will benefit all.

Attendees will receive: CP-60(15) Shotcrete Nozzleman Craftsman Workbook
This 7-hour program is a requirement for all shotcreters wishing to pursue certification as an ACI Shotcreter (formerly known as Nozzleman) through ASA. However, it also provides a great overview of the shotcrete process for contractors and project managers. This registration includes the required CP60 workbook (available in English or Spanish) and a complimentary 1-year ASA Shotcreter membership. (Registering for this class would also require you to sign up for an Exhibit-Only Pass, available for $25 using ASA’s source code: A17. Class is listed under Association and Industry Training.) Please note: this class alone will not result in certification. Opportunity for Wet-Mix certification is available, see Thursday option below.

With the strong growth of shotcrete construction, the concrete construction industry needs on-site inspectors who are knowledgeable about producing high-quality and durable shotcrete. This one-day session from ASA provides guidance on over 40 critical elements of shotcrete applications to properly evaluate the overall quality of shotcrete – valuable information for onsite inspectors, General Contractors, shotcrete contractors and others who hire shotcrete sub-contractors. Topics covered include material selections, equipment, placement techniques, finishing, curing, protection, testing and safety as it relates to the shotcrete process.
Examinees may purchase direct from ACI (www.concrete.org/store): ACI CP-61Pack – Shotcrete Inspector Reference Package. This is the reference resource permitted for the open book exam, optional for those individuals pursuing the ACI Shotcrete Inspector Certification, and also available at the seminar for an additional charge.
