Yankho la funsoli ndi losavuta popeza ndilo funso lolakwika kufunsa.Funso labwino ndilakuti ndi liti lomwe lili bwino pakugwiritsa ntchito kokonzekera chifukwa pali ma pro ndi ma con a onse awiri.SPC ndiukadaulo waposachedwa, koma sikuti ndiyabwino kwenikweni.Pachimake chimatsimikizira kuti ndi mankhwala ati omwe ali oyenera kugwiritsa ntchito.
Pakatikati pa SPC nthawi zambiri ndi 80% Limestone 20% PVC polima ndipo "sachita thovu" motero imakhala ndi kachulukidwe kakang'ono kwambiri, kumapangitsa kumva kolimba kwambiri.
WPC Nthawi zambiri 50% Limestone 50% PVC polima w/wowonjezera polima pachimake kumapangitsa kumva bwino pansi pa phazi.
Chinthu chotsatira chomwe muyenera kuganizira pogula WPC kapena SPC pansi ndi chomata kapena choyikapo pansi chomwe chimawonjezedwa ndi wopanga kuti apititse patsogolo kutsika kwa mawu komanso kutonthoza kwa phazi.Pali magulu atatu akuluakulu a underlayment.
Cork - Zonse Zachilengedwe, Zosatha, mwachibadwa zimakhala ndi SUBERIN (soo-BER-in) chinthu cha waxy chomwe chimatsutsana ndi nkhungu ndi mildew, chimasunga geji ndi kukhulupirika kwa moyo wapansi.
EVA - Ethylene Vinyl Acetate ndi polima ya elastomeric yomwe imapanga zinthu zomwe zimakhala ngati "mphira" mofewa komanso kusinthasintha.EVA imapezeka muzinthu zambiri zogula monga Flip Flops, Pool Noodles, Croc's ndi Underlayment poyandama pansi.EVA imakonda kutaya mawonekedwe ake apamwamba komanso omveka pa moyo wa chinthucho.
