I-Fiberglass isetyenziswe ngokubanzi kwizinto zokukhusela amanzi, kwaye iimpawu zayo ezilula, ezinamandla kunye nezizinzileyo ziye zakhokelela ekuphuculeni okubonakalayo kumgangatho wezinto zokukhusela amanzi. I-Fiberglass isetyenziswa njengento yokomeleza kwiingubo eziqhelekileyo zokungangeni manzi, i-membrane engenamanzi kunye ne-adhesives engenamanzi. I-Fiberglass exutywe nepeyinti, ifakwe phezu kwesakhiwo, yenza uluhlu lwesithintelo esinamandla kunye nesigxina, ukukhusela ngokufanelekileyo ukungena kwamanzi; i-fiberglass yomeleza inwebu yokungangeni manzi ngokuxhathisa kwamanzi, ukuxhathisa kwemozulu, ukumelana nokubanda, ukuxhathisa ubushushu, kodwa ikwazi ukumelana ne-flexural deformation kunye nokukrazula kunye nezinye iimeko; ukusetyenziswa kwe-fiberglass njengento yokuqinisa i-adhesive waterproofing inokwenza ukuba amandla okubambisana kwee-membrane zokuthintela amanzi aphuculwe kakhulu, ngaloo ndlela ephucula ukusebenza kwawo okungangeni manzi. Ukongeza, i-fiberglass nayo ingenamlilo, inxibe-resistant kunye nezinye iimpawu, ukwenzela ukuba umgangatho wokukhusela amanzi uphuculwe.
