Ko te RDP (Redispersible Polymer Powder) he tāpiri paura e whakamahia whānuitia ana i roto i ngā rauemi hanga, inā koa i roto i ngā hua sima pērā i ngā moata, ngā piripiri me ngā grout taera. Kei roto ko ngā kapia polymer (i te nuinga o te wā he mea hanga ki te vinyl acetate me te ethylene) me ngā momo tāpiri.
Ko te paura RDP e whakamahia ana mō ngā kaupapa e whai ake nei:
Ka Whakarei Ake i te Ngāwari me te Pakari: Ina tāpirihia ki ngā rauemi sima, ka whakanui ake te RDP i tō rātou ngāwari, te ngāwari me te ātete ki te pakaru. He mea nui rawa tēnei i roto i ngā tono e nekehia ana, e wiri ana rānei ngā rauemi, pērā i ngā piri taera, i te paninga o waho rānei.
Te Piripiri Pai Ake: Ka whakanui ake te RDP i te kaha o te here i waenga i ngā rauemi sima me ngā papa pēnei i te raima, te rakau, te taera, ngā papa whakamahana rānei. Ka whakarei ake i te piri, ā, ka whakaiti i te tūponotanga o te wehewehe, te wehewehe rānei.
Te Pupuri Wai: Ka āwhina te RDP ki te pupuri i te wai i roto i te ranunga sima, ka taea ai te makuku tika o te sima, ā, ka roa ake te mahi a te rauemi. He pai tēnei mō ngā tono e hiahiatia ana he wā mahi roa ake, he pai ake rānei te mahi miihini.
Te Whakarei Ake i te Māmā o te Mahi: Ka whakapai ake te RDP i te rere me te horapa o ngā rauemi sima, kia māmā ake ai te whakaranu, te whakahaere me te pani. Ka whakarei ake i te māmā o te mahi o te moata, ā, ka whakaiti i te nui o te mahi e hiahiatia ana i te wā hanga.
Te Pānga ki te Wā Whakatakoto: Ka pā te RDP ki te wā whakatakoto o ngā rauemi sima, ka taea ai te whakahaere nui ake i te tukanga whakatakoto. Ka taea e ia te āwhina ki te whakanui ake, ki te whakaiti rānei i te wā whakatū e hiahiatia ana mō tētahi tono motuhake.
Ātete Wai Whakapai Ake: Ka whakarei ake te RDP i te ātete wai o ngā rauemi sima, ka nui ake tō rātou ātete ki te urunga wai, ā, ka roa ake hoki te mau i ngā taiao mākū, haukū rānei.
He mea nui kia mōhiotia ko ngā āhuatanga motuhake me te mahi a ngā paura RDP ka rerekē pea i runga i te hanganga polymer, te rahi o te matūriki, me ētahi atu āhuatanga. Tērā pea ka tukuna e ngā kaihanga rerekē ngā hua RDP me ngā āhuatanga rerekē kua whakaritea mō ngā tono motuhake.
I te nuinga, he tāpiri maha-mahi te paura RDP mō ngā rauemi hanga e whakarei ake ana i te ngāwari, te piri, te ngāwari ki te tukatuka, te ātete ki te wai me te roa o ngā hua sima.
