Isikhwama somoya sokuvala amapayipi siwumkhiqizo wenjoloba owenziwe ngenjoloba, indwangu yefayibha nezinye izinto zokwenziwa ze-macromolecular ngokusebenzisa inqubo ye-vulcanization eshisa kakhulu, esetshenziselwa ukuthuthwa kwamanzi, ukuthuthwa kwendle kanye nokugcinwa kwe-desilting yamapayipi nama-culverts.Ingavimba ngokushesha ukugeleza kwamanzi kumadayimitha amapayipi ahlukene, izindiza ezihlukene kanye nezindawo ezihlukene, futhi iyithuluzi elikahle lamapayipi angaphansi komhlaba ukuze ahambise amanzi, ukugeleza kwamanzi kanye nokuhlanza udaka.
