Ama-Toppings, njenganoma yimuphi omunye ukhonkolo, angaphansi kwezincomo zemboni jikelele mayelana nemikhuba yokuthulula ukhonkolo sezulu esishisayo nesibandayo. Ukuhlela nokufeza okufanele kubalulekile ukuze kuncishiswe imiphumela emibi yesimo sezulu esibi kakhulu ekuqoqweni, ukuqinisa, ukusika, ukuphulukisa kanye nokuthuthukiswa kwamandla. Isici esibalulekile okufanele sicatshangelwe lapho uhlela umthelela wezimo zemvelo ekwakhiweni okuphezulu yikhwalithi yama-slabs aphansi akhona. Esimweni sezulu esishisayo nesibanda kakhulu, amapuleti aphezulu naphansi avame ukubekwa emazingeni okushisa ahlukene, kodwa azofinyelela ukulingana kokushisa ngesikhathi sokwelashwa. Ngokuvamile, i-base plate yenza iningi lebhodi eliyinhlanganisela (eliboshiwe noma elingahlanganisiwe), ngakho ukulungiswa kwe-base plate ngaphambi kokwakhiwa akukwazi ukuzitshwa. Ama-toppings azacile angase atholakale kalula ezinkingeni ezihlobene nezinga lokushisa. Amapuleti aphansi abandayo angabangela izinkinga zokuqeda ngenxa yokubambezeleka kokuqina, ukubambezeleka kokuzuza amandla, noma ngisho nangaphezulu eliqandisiwe uma lingalungiswanga kahle. I-hot base plate ingabangela ukuqina okusheshayo, okungaba nomthelela omubi ekusebenzeni, ukuhlanganiswa, ukuqeda kanye nokubopha. Iseluleko semboni sokubhekana nesimo sezulu esishisayo nesibandayo sibhalwe kahle; Nokho, ukuthululwa kukakhonkolo nakho kubhekana nezinye izingozi ezihlobene nesimo sezulu, njengemvula, imboni engazisho nhlobo. Isimo sezulu asibikezeleki, futhi ukubekwa ngokuvamile kwenziwa uma kunethuba lokuna kwemvula ukuze kuhlangatshezwane nezidingo zeshejuli yephrojekthi. Isikhathi, ubude besikhathi, kanye namandla ezivunguvungu zonke kuyiziguquko ezibalulekile ezithinta impumelelo yokubeka.

Ukuchayeka emvuleni ngesikhathi sokubekwa

Ezimweni eziningi, ukuthululwa kukakhonkolo okuchayeke emvuleni ngeke konakale uma amanzi emvula eningi esuswa ngaphambi kokuqedwa. Ngokusho kwe-Concrete Finishing Guide eshicilelwe yi-Cement Concrete & Aggregates Australia, uma indawo kakhonkolo iba manzi (efana nokopha), amanzi emvula adinga ukususwa ukuze aqhubeke nokuqeda. Kunokukhathazeka okuvamile ukuthi imvula ingase ikhulise isilinganiso sikasimende samanzi sokubeka, okuholela ekunciphiseni kwamandla, ukuncipha kokuncipha kanye nendawo ebuthakathaka. Lokhu kungaba yiqiniso uma amanzi engakwazi noma engasuswa ngaphambi kokuqedwa; nokho, usonkontileka ukhombisile ukuthi lokhu akunjalo lapho kuthathwa izinyathelo zokususa amanzi engeziwe. Izindlela zokuphepha ezivame kakhulu ukumboza ukhonkolo ngepulasitiki noma ukuchaya imvula bese ususa amanzi amaningi ngaphambi kokuqeda.

Uma kungenzeka, vala indawo ngepulasitiki ukuze unciphise ukuchayeka emanzini emvula. Nakuba lokhu kuwumkhuba omuhle, ukusetshenziswa kwepulasitiki kungaba nzima noma kungenzeki uma abasebenzi bengakwazi ukuhamba phezulu, noma ishidi lepulasitiki alibanzi ngokwanele ukumboza bonke ububanzi bendawo, noma ukuqinisa noma ezinye izinto zokungena ziphuma phezulu. . Abanye osonkontileka baphinde baxwayise ngokusebenzisa ipulasitiki ngoba igcina ukushisa futhi ibangele ukuthi indawo engaphezulu isheshe imiswe. Ukunciphisa iwindi lokuqeda kungase kungathandeki kulezi zimo, njengoba kungase kudingeke isikhathi esengeziwe sokususa amanzi futhi uqedele umsebenzi wokuqeda.

Ibhodi elisha lingambozwa ngepulasitiki ukuvikela indawo engaphezulu phakathi nezivunguvungu ezingalindelekile.

Amanzi emvula engeziwe angasuswa phezu kwama-slabs amasha ngokusebenzisa ipayipi lengadi noma amanye amathuluzi ayisicaba njengama-scrapers namashidi aqinile okuvikela.

Osonkontileka abaningi babeka obala izindawo bese bechaya imvula. Ngokufanayo nokuphuma kwamanzi, amanzi emvula awamuncwa i-floor slab, kodwa kufanele ahwamuke noma asuswe ngaphambi kokuqedwa. Abanye osonkontileka bancamela ukuhudula ipayipi elide elingadini phezu kwe-slab ukuze basuse amanzi amaningi, kuyilapho abanye bekhetha ukusebenzisa isikrufu noma ubude obufushane bokufakwa kwegwebu eliqinile ukuze baqondise amanzi phansi kwe-slab. Enye i-grout engaphezulu ingase isuswe ngamanzi amaningi, kodwa lokhu ngokuvamile akuyona inkinga njengoba ukuqedela okwengeziwe ngokuvamile kuletha i-grout ngaphezulu.

Osonkontileka akufanele basabalalise usimende owomile ngaphezulu ukuze basize ukumunca amanzi emvula amaningi. Nakuba usimende ungase usabele ngamanzi emvula amaningi, ukunamathisela okuwumphumela kungase kungahlangani endaweni ye-slab. Lokhu kubangela izinga eliphansi eliphansi elivame ukuthambekela ekuxebukeni kanye ne-delamination.
