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.

When applying 6 in. (152 mm) of shotcrete on an exterior concrete surface, how long should that cure before coating with an acrylic elastomeric roof coating? What is the moisture content of that thickness after 7 days, or after 14 days?
Shotcrete is just a placement method for concrete. Thus, the in-place material will have the same characteristics as concrete. You should consult the coating supplier to establish how long they want the concrete surface cured. They may also specify a certain limit for surface moisture conditions. There are several methods for evaluating the moisture content of the in-place concrete. Here are the ASTM standards that deal with surface moisture:
- ASTM F710, Preparing Concrete Floors to Receive Resilient Flooring; Section 5.2, pH Testing;
- ASTM F1869, Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride;
- ASTM F2170, Determining Relative Humidity in Concrete Floor Slabs Using in situ Probes;
- ASTM F2659, Preliminary Evaluation of Comparative Moisture Condition of Concrete, Gypsum Cement and Other Floor Slabs and Screeds Using a Non-Destructive Electronic Moisture Meter; and
- ASTM F3191, Field Determination of Substrate Water Absorption (Porosity) for Substrates to Receive Resilient Flooring.
In addition, The International Concrete Repair Institute (ICRI) has a certification program, “ICRI Concrete Slab Moisture Testing Technician—Grade 1.”
How thick would you recommend a shotcrete application be to make bedrock reservoir waterproof?
There are many variables that would need to be considered to answer your question. Water flow, depth of the application, and overall geometry can influence the required thickness. This is a question that should be addressed by an experienced engineer who can ascertain the required structural properties to resist the hydraulic loads for the depth and geometry of your application. You may find consultants who are ASA Corporate Members in our Buyers Guide.
