Zvinhu zvinonamira zvisingapindi mvura zvinonamira imhando yezvinhu zvisingapindi mvura zvakagadzirwa nerabha asphalt inonamira pachayo yakagadzirwa kubva kuSBS nedzimwe rabha dzekugadzira, tackifier uye asphalt yepetroleum yemhando yepamusoro seyakavakirwa, firimu rakasimba uye rakasimba repolyethylene repamusoro-soro kana foil yealuminium sedata repamusoro, uye diaphragm inobviswa nesilicon kana pepa rekudzivirira rinobviswa nesilicon sedata rekudzivirira rinonamira pamusoro pepasi.

Imhando itsva yezvinhu zvisingapindi mvura zvine tarisiro yakakura yekukura. Ine hunhu hwekuchinjika kwekupisa kushoma, kuzviporesa uye kushanda zvakanaka kwekubatanidza. Inogona kuvakwa patembiricha yemukamuri, nekukurumidza kuvaka uye inosangana nezvinodiwa zvekuchengetedza nharaunda. Rubha Asphalt inonamira pachayo. Zvinhu zvisingapindi mvura zvinonamira pachayo, zvinhu zvisingapindi mvura zvinonamira pachayo zvine resin yakawanda uye asphalt yemhando yepamusoro seyakavakirwa, polyethylene film uye aruminiyamu foil sedata rekuonekwa, uye setafura inoparadzanisa.
Chigadzirwa ichi chine simba guru rekubatanidza uye chinozviporesa, uye chakakodzera kugadzirwa munzvimbo dzine tembiricha yakakwira uye yakaderera. Chinogona kukamurwa kuita matai anonamira ega uye asina matai. Tai rine nzvimbo dzinonamira dzepamusoro nepazasi dzakasungirirwa nechigadziko chematai. Chifukidziro chepamusoro ifirimu revinyl uye chifukidziro chepazasi ifirimu resilicone rinobviswa. Chinonamira chega chisina matai chine firimu rinonamira ega, firimu repamusoro revinyl uye firimu repasi resilicone oil.
Chigadzirwa ichi chine basa rakanaka rekudzivirira kupisa kwakaderera. Ndiyo data rakanakisa rinodzivirira mvura, rinodzivirira hunyoro uye rinovhara nzvimbo dzepasi pevhu, mugero uye nzvimbo dzinopisa dzekushandira. Chakakodzerawo pakugadzira mapaipi asingapindi mvura uye anodzivirira ngura. Hapana chikonzero chekuti chinamira kana kupisa zvinyunguduke. Ingobvarura layer yekudzivirira uye inogona kusungirirwa zvakasimba kune layer yepasi. Kuvaka kuri nyore uye kumhanya kwekuvaka kunokurumidza zvikuru.
