Peb Cov Khoom Siv Geomembrane (Geotextile-Geomembrane Composites) yog tsim los ntawm kev sib txuas ntawm cov khoom siv hluav taws xob tsis yog geotextile rau geomembranes. Cov khoom sib xyaw muaj cov haujlwm thiab qhov zoo ntawm ob qho tib si geotextile thiab geomembrane. Cov geotextiles muab kev tiv thaiv ntau ntxiv rau kev sib tsoo, tsim kua muag tawm, thiab kev sib txhuam cuam tshuam nrog zawv zawg, nrog rau muab lub zog tensile hauv thiab ntawm lawv tus kheej.
