I-Concrete PolyLock, ebizwa ngokuba yi-E-lock okanye i-polylock, eyenziwe nge-HDPE, i-E-shaped, ifanelekile ukubambelela kwikhonkrithi ngokuqinileyo. Iphoswe okanye ifakwe kwikhonkrithi emanzi xa usebenzisa, kwi-welding surface evezwayo, i-geomembrane inokudityaniswa kuyo ngokulula. Umphezulu ogudileyo kunye nobubanzi obuyi-15cm okanye i-10cm yeyokuwelda amashiti e-polyethylene ngelixa iminwe yokuphakama kwe-3-4cm isetyenziselwa ukufaka ikhonkrithi yewebhu ukuze itshixiwe kwaye ilungise umdibaniso kunye ne-geomembrane ukwenza ibhanki epheleleyo yobungqina bamanzi.
