Tēpu Ko Coastline he tēpu i whakaarohia mai i te pikinga o te taumata moana nā te whakamahana ā-ao. Ko te mata o te tēpu he mea hanga ki te akiriki, e mōhiotia ana hoki ko te PMMA, ā, kua whakaahuahia mā te whakamahana taumaha-nui hei tohu i te wai moana mārama. Ko te hanganga tautoko he mea hanga ki te rākau michelia compressa me te paina, ā, e tohu ana te rākau i te teitei o ngā maunga. I tīpakohia he rākau maro kia kore ai te hanganga e piua i te wā e whakamahanatia ana. Ko te tapa kōeke e whakamahara ana ki tētahi takutai moana kua ngaua e te moana, ā, mā te whakakotahitanga o ngā rauemi ka taea e te māramatanga te uru mā ngā papa maha. Ko ngā nekehanga o te tēpu he 350 mm te whānui, 650 mm te hōhonu me te 500 mm te teitei.
