Three outdoor experiments are reported where a wrinkle was allowed to develop and grow in a narrow strip of 2-mm-thick HDPE geomembrane when subjected to solar heating. The increase in length of the strip was used to obtain an effective coefficient of thermal expansion for the particular configurati...
