The International Code Council (ICC) is responsible for producing the International Building Code (IBC) and the International Residential Code (IRC). The ICC-Evaluation Service (ICC-ES), a subsidiary of ICC, is a nonprofit, public-benefit corporation that performs technical evaluations of building products, components, methods, and materials. ICC-ES evaluation reports provide evidence that products and systems meet specific performance requirements of the building code. An accredited laboratory since 1992, WJE has tested a variety of materials following ICC-ES standards and criteria.


WJE engineers and materials scientists performed a variety of tests in accordance with ICC-ES AC 193 and AC308:

Reference tests to determine baseline performance values for reliability and service-condition

Reliability tests used to establish anchor capabilities in the likely event of adverse installation procedures

Service condition tests used to determine the performance of anchors under service conditions

Spacing and edge distance tests

Overhead and horizontal installation performance tests of adhesive anchors

Performance of anchors in un-cracked and cracked concrete

Repeated load tests

The results were tabulated in a product evaluation report published by ICC-ES and were used for the design of post-installed anchors in accordance with ACI 318, Appendix D.
