Inganda z'ubwubatsi zikomeje gutera imbere zigana ku bikoresho by'ubwubatsi bikora neza, bikoresha ingufu nke kandi biramba. Ibikoresho gakondo bishingiye kuri sima bikunze kugira imbogamizi nka:

• Ubworoherane buke
• Kutamenya neza
• Uburibwe bwinshi
• Ibibazo byo kwangirika
• Ubudahangarwa bw'amazi buke

Kugira ngo bikemure ibi bibazo, imvange zigezweho za mortilage zumutse zikoresha inyongeramusaruro zigezweho za polymer. Muri zo,Ifu ya polymer ishobora gukurwamo (RDP)yabaye kimwe mu bikoresho by'ingenzi bikora.

RDP ni ifu ya polimeri yatunganyijwe mu buryo bwihariye ishobora kongera gushonga mu mazi no kongera gukora emulsion ya polimeri ihamye. Iyo yongewe muri sisitemu zishingiye kuri sima, RDP ikora firime ya polimeri yoroshye irushaho kunoza cyane:

• Imbaraga zo gufata
• Guhindura imiterere
• Ubudahangarwa bw'imipfundo
