Efflorescence Study, Fort Leonard Wood, Missouri

The U.S. Army Engineer Waterways Experiment Station (WES) was asked to assist in the investigation of the efflorescence problem at Fort Leonard Wood, Missouri. An inspection of the buildings at Fort Leonard Wood was made by WES personnel on 26 January 1993. Personnel from the U.S. Army Engineer Division, Missouri River, U.S. Army Engineer District, Kansas City, and Headquarters, U.S. Army Corps of Engineers, were also present for the inspection. A Research Proposal (Appendix A) was prepared by WES, and this study was begun in February 1993. A survey was made through a literature search and contacting consultants and professional organizations to determine what could he done to eliminate or reduce efflorescence in existing structures and what could be done to construction specifications or practices to prevent/ reduce efflorescence in new construction. The Commissary building at Fort Leonard Wood was selected as the site for field testing which included: (1) tuckpointing of mortar joints, (2) application of surface sealers, and (3) water penetration tests.
