Undlunkulu weDonsen (A umzi-mveliso) uvelisa izifakelo zemibhobho yePPR, izifakelo zemibhobho ye-PE kunye nezinye iimveliso zonikezelo lwamanzi kunye nazo zonke iintlobo zeevalvu. Umzi-mveliso we-B ubukhulu becala uvelisa izixhobo zemibhobho yePVC, izixhobo zemibhobho ye-HDPE kunye nezinye iimveliso zokuhambisa amanzi; Umzi-mveliso we-C uvelisa ubukhulu becala imibhobho yocinezelo yePP kunye nezinye iimveliso zezolimo zonkcenkceshelo ezigcina amanzi. Umzi-mveliso wokubumba unoxanduva lokuvelisa zonke iintlobo zokubumba umbhobho kwaye umzi-mveliso omtsha uya kwandisa kakhulu imveliso yokufakelwa kwemibhobho yethu, iivalve, imibhobho.
Okwangoku, inkampani iphumelele isiqinisekiso se-CE se-European Union. Isiqinisekiso se-NSF e-USA; isiqinisekiso se-SABS eMzantsi Afrika; Ukuqinisekiswa kweGOST eRashiya; Isiqinisekiso se-WRAS eNgilani, isatifikethi se-SIAA eJapan; Isatifikethi se-SKZ saseJamani kunye nesinye isiqinisekiso.
Iimveliso zethu zithunyelwa kumazwe angaphezu kwe-100 ehlabathini, anjengeRashiya, iUkraine, iFransi, iItali, iMexico, uMbindi Mpuma, iYurophu, uMzantsi Merika, iAsia, njl.
