Abstract
Various types of geosynthetics have been manufactured and their applications are rapidly extended disregarding unreliable lifetime, chemical and biological persistence and puncture resistance. Puncture resistance of geosynthetics in earth structures and liner systems has been a critical issue to be improved. In this paper, comparative studies were made on a puncture resistance of various geosynthetics that were used to a liner system. Two types of puncture tools and rubles and gravels were used to generate punctures on geosynthetics. From the results it is shown that types of puncture tools affect puncture resistance of materials significantly and puncture forces were irregular depending upon puncture tools and materials.
