1.1 Cov khoom siv zoo ntawm lub cev thiab lub zog
Geotextiles muaj qhov chaw ua haujlwm hnyav. Ntau qhov xwm txheej, lawv tau tsau dej los yog muab tso rau hauv av nrog cov av noo, yog li lawv yuav tsum muaj cov hydrolysis zoo thiab cov khoom ntub dej.
1.2 UV hluav taws xob tsis kam, hydrolysis tsis kam, siab thiab tsis kub tsis kam
Geotextiles yuav tsum tau raug rau lub hnub ci, yog li lawv yuav tsum muaj sib txuam UV tiv taus; geotextiles yuav tsum tau ua kom haum rau qhov kub ntawm qhov chaw uas lawv nyob rau hauv kev sib cuag nrog cov ntaub ntawv xws li asphalt, xav kom lub siab yaj dua.
1.3 Tshuaj lom neeg tsis kam, corrosion kuj, kuj mildew
Cov dej thiab cov av muaj ntau qhov sib txawv, qee qhov yog alkaline, qee qhov yog acidic, qee qhov muaj ntsev ntau, qee qhov muaj ntau cov ntsiab lus, yog li lawv yuav tsum muaj cov tshuaj lom neeg ruaj khov.
1.4 Zoo dej permeability
Geotextile pom thiab cov dej ntws pov tseg xav tau cov dej permeability thiab yuav tsum yog li ntawd muaj cov dej zoo permeability.
