Abstract:

Butyl rubber sheeting is one of the materials offering possibilities as an improved roofing product. A specimen of 30-mil butyl rubber has remained in excellent condition after 7 years exposure in our outdoor test where the lower portion of the panel remains under water continuously. The upper portion is exposed to the atmosphere, and an alternating wet and dry condition exists at the center of the test panel. Butyl rubber sheeting has been installed as a test canal lining on two projects and is presently in excellent condition and watertight after 2-12 years. Author
