Kev tsim kom muaj dej ruaj khov- tuav cov qauv yuav tsum muaj qhov sib npaug ntawm cov khoom siv zog thiab kev ncaj ncees ntawm qhov chaw. Ntau tus neeg cog lus tau hloov mus deb ntawm cov cement slurries mus rau qhov ua tau zoo -pas dej ua ke waterproofing mortarvim nws muaj kev sib xyaw ua ke ntawm inorganic durability thiab polymer yooj. Tsis zoo li cov txheej txheem mortars uas tej zaum yuav tawg nyob rau hauv me me hloov nyob rau hauv av, cov ntaub ntawv no tsim ib tug ntom, tsis yog - zaj duab xis tshuaj lom neeg uas muaj zoo tiv thaiv hydrostatic siab. Hauv kev tsim kho kev lag luam tam sim no, peb pom ob hom tseem ceeb: cov txheej txheem nruj rau hnyav- lub hauv paus ua haujlwm thiab cov ntaub nyias nyias rau cov cheeb tsam uas muaj kev vibration lossis me me. Qhov sib txawv ntawm qhov tshwj xeeb mortar thiab cov tsoos bitumen txheej yog nyob rau hauv nws breathability; nws tso cai rau cov vapor sab hauv kom khiav tawm thaum tiv thaiv cov dej los ntawm kev nkag mus rau hauv cov pob zeb. Qhov no tiv thaiv cov teeb meem tshwm sim ntawm delamination, qhov twg cov vuas pib pop tawm ntawm phab ntsa vim muaj cov dej ntws. Los ntawm kev ua raws li cov qauv kev tsim vaj tsev ntsuab thoob ntiaj teb, cov polymer no- kho cov kev daws teeb meem kom ntseeg tau tias cov dej tseem muaj kev nyab xeeb rau cov neeg ua luam dej thaum tiv thaiv cov khoom siv hlau sab hauv los ntawm kev xeb ntxov ntxov.
Kev ua tiav ib qho kev foob zoo yog nyob ntawm kev ua raws li kev thov kom raug thiab saib xyuas cov khoom siv raw zoo. Ua ntej pib, lub substrate yuav tsum huv si, ruaj, thiab ntub me ntsis kom ntseeg tau tias muaj kev sib raug zoo. Cov xov xwm kev lag luam tam sim no qhia txog tus qauv mus rau cov khoom siv ruaj khov dua, nrog cov tuam txhab tsim khoom eco- cov khoom siv polymer zoo uas txo cov pa roj carbon monoxide tag nrho ntawmpas dej ua ke waterproofing mortar. Txhawm rau siv cov khoom, koj feem ntau sib tov cov hmoov nrog dej ntawm qhov sib piv ntawm kwv yees li 1: 3.5, siv lub tshuab stirrer kom ncav cuag lub pob -dawb, creamy sib xws. Nws yog qhov zoo tshaj plaws siv rau hauv ob txheej nyias, txhua qhov txog 1 hli tuab, nrog rau lub tsho thib ob siv perpendicular mus rau thawj zaug thaum thawj txheej yog kov - qhuav. Txoj kev "cross-hatch" no tau lees tias tsis muaj pinholes lossis nyias me ntsis hauv qhov thaiv. Cov kws tshaj lij hauv kev lag luam dej tsis zoo qhia tias txawm tias cov khoom siv zoo tshaj plaws yuav ua tsis tiav yam tsis muaj kev kho kom zoo, yog li ua kom lub ntsej muag ntub dej rau ob peb hnub tom qab daim ntawv thov yog ib kauj ruam tseem ceeb. Kev siv cov txheej txheem no ua kom ntseeg tau tias muaj kev ruaj ntseg, xau{11}}dawb tiav uas sawv cev rau cov tshuaj hnyav thiab cov dej tsis tu ncua ntawm txhua qhov chaw ua luam dej.
