Zimapangidwa ndi polyethylene yapamwamba kwambiri (Zithunzi za HDPE) pepala, polima amphamvu anachita kudziona zomatira nembanemba ndi wapadera kudzipatula nembanemba zoteteza wosanjikiza.Ndi mtundu wa zinthu zosanjikiza zambiri zosanjikiza madzi zokhala ndi magwiridwe antchito apamwamba kwambiri opangidwira magawo a ntchito zapansi panthaka zomwe zimayenera kumangidwa ndi njira yopangira kale.Zinthuzo zimakhala ndi mphamvu yabwino yolimbikira komanso mphamvu yong'ambika.Ndi mtundu watsopano wa zinthu zopanda madzi zomwe zimagwira bwino ntchito muukadaulo wapansi panthaka.
Pansi pa kukakamizidwa, polimafilimu yodzimatirandi simenti slurry popanda kukhazikitsa koyamba mu konkire adzakwawa kudzera odana adhesion wosanjikiza kupanga ogwira interpenetrating chomangira ndi yaikulu intermolecular mphamvu.Pambuyo konkire ndi olimba, kusiyana pakati pa polima kudziona zomatira nembanemba madzi nembanemba ndi dongosolo lalikulu ndi mpaka kalekale losindikizidwa kumlingo pazipita, ndi madzi channeling njira kwathunthu inathetsedwa.

Imagwiritsidwa ntchito ku zomangamanga zopanda madzi komanso zonyowa potsimikizira uinjiniya wanyumba zosiyanasiyana zapansi panthaka, malo osungira mapanga, ma tunnel, ma subways ndi nyumba zina zomanga zamatauni etc.
Pepala lodzimatira la HDPE polima (lopanda phula) lopanda madzi limapangidwa ndi ma polima osiyanasiyana.
mapepala monga zipangizo m'munsi yokutidwa ndi mmodzi kudziona zomatira wosanjikiza ndi kudzipatula nembanemba kapena mchenga wosanjikiza monga isolatinglayer.Kuphatikiza apo, pepala la polima limaphatikizapo mapulasitiki osiyanasiyana mongaZithunzi za HDPE, TPO, Zithunzi za PVC, EVA, ECB, ndi elastomer mongaChithunzi cha EPDM.
(1) Pangani "mtundu wa khungu" mphamvu yoletsa madzi, kuchotsa njira zamadzi.
(2) Mukayenerera, sonkhanitsani mwachindunji chilimbikitso ndikutsanulira konkriti yomanga.
(3) Kumanga kosavuta, nthawi yochepa yomanga.
(4) Kukaniza kwabwino kwambiri komanso nyengo, komanso moyo wautali.
(5) Kugwirizana kwabwino.
(1) Ntchito za Municipal: Sitima yapansi panthaka ndi ngalande yapansi panthaka.
(2) Msewu: Msewu waukulu.
(3) Sitima yapamtunda: Ngalande yanjanji yothamanga kwambiri
(4) Zomangamanga zamafakitale ndi zachitukuko: Basement maziko apansi ndi khoma lakumbali lomwe linamangidwa mwa njira yopewera kunja ndi kumata mkati.
