Ceev faj tsis txhob cia pob zeb, hmoov av ntau, thiab lwm yam uas yuav ua rau lub geotextile puas, cuam tshuam rau cov kua dej los yog pom hauv geotextile. Tom qab kev teeb tsa, tshuaj xyuas qhov chaw puas ntawm qhov chaw ntawm geotextile, kos nws thiab kho nws kom ntseeg tau tias tsis muaj cov khoom uas tuaj yeem ua rau puas tsuaj.
