An Adhesive Anchor Installer is an individual who has demonstrated the ability to read, comprehend, and execute instructions to properly install adhesive anchors in concrete. The Adhesive Anchor Installer must also demonstrate possession of the knowledge to properly assess ambient conditions, concrete condition, materials, equipment, and tools for installing adhesive anchors and determine when it is appropriate to proceed with installation of an adhesive anchor or when additional guidance from a supervisor/foreman/project engineer is needed.

Scope and Knowledge:

This program requires demonstration of the knowledge and hands-on skills covered on the Job Task Analysis (JTA) for Adhesive Anchor Installer: 

Job Task Analysis (JTA) for ACI Adhesive Anchor Installer Certification

The JTA is a detailed list of specific points of knowledge and skills that may be included in the examinations for this ACI Certification program. ACI urges candidates to use the JTA to prepare for the certification exams.

Certification Requirements:

ACI will grant certification only to those applicants who obtain a passing grade on both the written examination and performance examinations. 

  1. The 90-minute written examination is closed-book and consists of 75 multiple-choice questions. To pass the written exam the examinee must attain a minimum score of 74%.
  2. The performance examination consists of two parts, Part 1 (vertical down) and Part 2 (vertical up):
    • In Part 1, each examinee will be tasked with selecting, assembling, and using the proper tools, equipment and materials to drill and clean a vertical down hole in concrete, inject adhesive, and set an anchor to the proper depth and perpendicularity. The Examiner(s) will observe and evaluate the examinees’ performance for proper procedure.
    • In Part 2, each examinee is required to inject clear tubes with adhesive in a vertical up orientation behind a blind to simulate a drilled hole in concrete; one tube is injected using the retaining cap method, and one tube is injected using the piston plug method. The Examiner(s) will observe and evaluate the examinees’ performance for proper procedure.

Following Part 1, the Examiner(s) will check the vertical down installation for proper depth and plumb; after the adhesive in the tubes injected in Part 2 has cured, the Examiner(s) will cross section them and evaluate the size and location of air voids to determine pass or fail. This program now certifies candidates in either OR both of the "overhead" installation systems (retaining-cap and piston-plug). 

A set of instructions appropriate for the exam along with applicable Material Safety Data Sheets (MSDS) will be available for consultation by the examinee during both parts of the performance exam. Both parts of the performance must be successfully completed within one year or the entire performance examination must be re-taken. 

Recertification is necessary every five years and requires successful completion of both the written and performance examinations.
