INVESTIGATION OF NONMETALLIC WATERSTOPS. REPORT 6. EFFECT OF EXPOSURE.
Abstract
Samples of rubber, synthetic rubber, and polyvinylchloride (PVC) waterstops, both stressed and unstressed, were exposed to freezing and thawing in a cold marine environment, to wetting and drying in a warm marine environment, to cold fresh water, to cold contaminated water, to warm fresh water, to warm contaminated water, to a moderate climate outdoors, to air without sunlight indoors, and to a weak solution of sodium and magnesium sulfate. Results indicate that PVC, neoprene, and natural rubber are all satisfactory materials for the production of nonmetallic waterstops. A good grade PVC would probably have the longer service life under most conditions. There is, however, more danger of getting a poor grade material unless laboratory testing for compliance with rigid specifications is required. (Author)
