Geomembranes multiaxial tensile test

Application of geomembranes in building trade is widespread but it can be said that they have got a function of a sealing layer. As such, in addition to the sealing properties, they should also have satisfactory tensile characteristics. Their application on the waste disposal locations can be twofold, in the lower sealing layers or as a part of the covering layers. In the lower sealing layers, their function is to prevent penetration of elauates (waste seepage waters) into the soil, and in particular into the ground waters, while in the covering sealing layers, the geomembrane has a function of preventing the penetration of precipitation waters into the dumpsite body, and preventing the uncontrolled emission of dumpsite gases (CO2-carbon dioxide, and CH4-methane) into the atmosphere. This paper deals with the geomembranes multi-axial tensile testing. The results of multi-axial tensile testing are compared to those obtained by uniaxial tensile testing.
