Abstract : This report describes the investigation of nonmetallic waterstops being conducted to evaluate the durability of waterstops of various types and materials. It describes results of additional laboratory tests on materials previously tested, and of laboratory tests on two new materials, gives conditions of speciments which have been subjected to various types of field and laboratory exposure for periods of about two to five years, and includes a summary of the service record of nonmetallic waterstops in U. S. Army Corps of Engineers field installations. Twenty-two nonmetallic waterstop materials are included in these tests, consisting of: 12 standard or cold- weather PVC, 2 polyethylenes, and 8 natural or synthetic rubbers. These materials were received both as finished waterstops and as sheets certified to be of the same material as the finished waterstops. The laboratory tests were performed on samples taken from the sheets, and the exposure tests on finished waterstops. The results of the tests and observations of the effects of the various exposure conditions are reported. (Author, modified-PL)
