Repair Application Procedures

ICRI adopted a revised mission in 2004, which is: …to be a leading resource for education and

information to improve the quality of repair, restoration, and protection of concrete and other structures. Part of being the leading resource is to know what information other organizations have developed on the topic of concrete repair and whether to make this information available to our members.

In this spirit of cooperation, ICRI has been publishing Repair Application Procedures (RAP) Bulletins, developed by the American Concrete Institute (ACI). We published the first two in 2004, two more in 2005, and will continue to publish them periodically. These bulletins are “how-to” documents for commonly used concrete repairs. ACI is allowing ICRI to publish them in the CRB,

as they are of great benefit to our members. These documents are also available, free of charge, on ACI’s website: www.concrete.org.

Each bulletin gives a concise description of the repair method, including the purpose of the repair, when it should be used, needed surface preparation, material and equipment selection, and safety consid-erations. Step-by-step procedures are also included to help repair technicians do their jobs correctly. These bulletins are useful reference documents for facility owners, design professionals, and concrete repair contractors.

Users are encouraged to tear out these pages for handy reference or, if you prefer, download these documents from ACI’s website, make copies for distribution to your field personnel, and file them for future reference.
