Txawm li cas los xij, nrog kev siv dej hauv chav da dej, ib txwm muaj kev pheej hmoo ntawm dej puas tsuaj. Qhov no yog vim li cas chav da dej yuav tsum muaj kev ruaj ntseg thiab txhim khu kev qha waterproofing. Ib chav da dej zoo yuav tsum muaj plaub qhov kev tsim dej tsis zoo. Cov qauv tsim no yog tsim los ua kom tiav, 360- tiv thaiv dej. Hauv tsab xov xwm no, peb yuav saib plaub tus qauv tsim thiab lawv ua haujlwm ua ke los tsim chav da dej tsis zoo.

Yuav kom daws tau qhov no, ib lub waterproofing membrane yog ntsia hauv qab cov vuas. Lub membrane tuaj yeem ua los ntawm ntau yam ntaub ntawv xws li PVC, polyethylene lossis CPE. PVC yog cov khoom siv feem ntau siv hauv chav da dej da dej. Nws yog tus nqi-zoo thiab yooj yim rau nruab. Tom qab ntawd cov ntaub thaiv dej tsis zoo yog muab tso rau hauv pem teb, kom paub tseeb tias nws tau kaw zoo ntawm cov phab ntsa thiab tag nrho lwm qhov qhib hauv pem teb.
2. Phab ntsa Waterproofing
Qhov thib ob tseem ceeb tsim yog phab ntsa waterproofing. Cov phab ntsa ntawm chav da dej tuaj yeem tiv tauj nrog dej ntau zaus thaum siv. Yog li ntawd, lawv kuj raug rau dej puas tsuaj. Txoj kev yooj yim tshaj plaws los tiv thaiv cov phab ntsa yog los ntawm kev siv cov txheej txheem waterproofing rau lawv. Cov txheej tuaj yeem yog daim ntawv ua kua lossis daim ntawv. Cov txheej txheej ua kua yog pleev xim ncaj qha rau ntawm phab ntsa, thaum daim ntawv daim ntawv raug ntsia raws li daim nyias nyias zoo li hauv pem teb daim nyias nyias. Cov phab ntsa yuav tsum tau kho kom zoo, thiab yuav tsum tau saib xyuas rau txhua qhov sib koom ua ke thiab lub kaum sab xis kom tsis txhob muaj dej ntws tawm.
3. Da dej taub hau Waterproofing
Lub taub hau da dej lossis da dej saum taub hau yog lwm qhov dej hauv chav da dej uas yuav tsum tau hais txog. Txhawm rau tiv thaiv kom tsis txhob muaj dej tawm, lub taub hau da dej yuav tsum tau muab kaw kom zoo kom tsis txhob muaj dej tawm ntawm cov khoom siv thiab mus rau hauv phab ntsa. Cov neeg ua haujlwm kav dej siv cov kav dej cement lossis cov khoom sib khi los kaw qhov kev sib txuas ntawm lub taub hau da dej thiab cov khoom siv dej. Lub sealing yuav tsum tau kuaj xyuas tsis tu ncua kom tsis txhob muaj qhov xau.
4. Dej pov thawj
Qhov kawg waterproofing tsim yog qhov ntws. Cov dej ntws hauv chav da dej yog qhov chaw tawm rau txhua qhov dej uas ntws hauv pem teb thiab phab ntsa.

Cov dej ntws yuav tsum muaj kev ruaj ntseg txuas rau hauv pem teb cov ntaub thaiv dej kom tsis txhob muaj dej los ntawm cov dej ntws los ntawm ob sab. Ib qho kev txhim khu kev qha thiab txhim kho kom zoo yog qhov tseem ceeb los tiv thaiv cov dej thaub qab lossis kev puas tsuaj rau chav da dej.
Hauv kev xaus, chav da dej zoo yuav tsum muaj 360-degree waterproofing. Plaub tus qauv tsim peb tau npog txhua lub luag haujlwm tseem ceeb hauv kev ua kom chav da dej tsis muaj dej. Ib qho kev txhim kho zoo thiab tswj xyuas cov dej tsis zoo yuav ua kom koj chav da dej nyob hauv qhov chaw ua haujlwm thiab tiv thaiv kev kho tus nqi vim dej puas tsuaj. Nrog rau kev tsim thiab kev teeb tsa kom zoo, koj chav da dej yuav yog qhov chaw so thiab rov ua dua tshiab rau xyoo tom ntej.
