Abstract

Et vannpenetrasjonshindrende materiale omfattende en vannsvellbar, vannabsorberende harpiks og et dekningsmateriale som omfatter minst to ark, idet den vannsvellbare, vannabsorberende harpiks holdes i dekningsmaterialet og i det minste en del av dekningsmaterialet er vanngjennomtrengelig. En vannpenetra- sjonshindrende struktur omfatter det vannpenetrasjonshindrende materiale anord- net mellom kabelen og beskyttelsesrøret i undergrunnskabelen med beskyttende rør. Ovennevnte vannpenetrasjonshindrende materiale og vannpenetrasjonshind- rende struktur hindrer vann som er kommet inn, fra å lekke inn i et mannhull, ved å hindre at vannet kommer inn gjennom et rom mellom kabelen og det beskytten- de rør, eller ved at vannet som er kommet inn, holdes i en bestemt del mellom kabelen og det beskyttende rør.
