Bet\u00f3n vodotesn\u00fd<\/h2>\n

Expert zna\u010dky Hydrostop, Marek Mularczyk, n\u00e1m porozpr\u00e1va o vodotesnom bet\u00f3ne.<\/h3>\n

Zva\u017eujete vykonanie hydroizol\u00e1cie, ale neviete, ak\u00e9 materi\u00e1ly si vybra\u0165?<\/p>\n

Spolu s expertom zna\u010dky Hydrostop, Marekom Mularczykom, sme pripravili kr\u00e1tku s\u00e9riu venovan\u00fa hydroizol\u00e1cii. Tu n\u00e1jdete odpovede na ot\u00e1zky: \u010co je hydroizol\u00e1cia? Ako vykona\u0165 hydroizol\u00e1ciu? Je potrebn\u00e1 hydroizol\u00e1cia z\u00e1kladov? \u010co je vodotesn\u00fd bet\u00f3n?<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Bet\u00f3n vodotesn\u00fd<\/h3>\n

Bet\u00f3ny vodotesn\u00e9 s\u00fa ve\u013emi popul\u00e1rne v stavebn\u00edctve u\u017e mnoho rokov. Av\u0161ak po\u010das mojej kari\u00e9ry som nieko\u013eko mesiacov pracoval v beton\u00e1rskej prefabrik\u00e1cii a viem, \u017ee bet\u00f3n je vodotesn\u00fd, ke\u010f sa testuje vzorka vyroben\u00e1 z tohto bet\u00f3nu. Ako mlad\u00fd in\u017einier som bol za to zodpovedn\u00fd, tak\u017ee som vykon\u00e1val ide\u00e1lne vzorky, uchov\u00e1val ich v ide\u00e1lnom, vlhkom prostred\u00ed. Vzorky boli starostlivo o\u0161etrovan\u00e9 a v\u0161etky testy dopadli v\u00fdborne.<\/p>\n

Av\u0161ak treba si uvedomi\u0165, \u017ee na stavenisku nie je laborat\u00f3rium, na stavenisku s\u00fa atmosferick\u00e9 podmienky, na ktor\u00e9 nem\u00e1me vplyv alebo m\u00e1me vplyv len \u010diasto\u010dne. \u010co sa teda deje v t\u00fdchto podmienkach s vodotesn\u00fdm bet\u00f3nom? Bohu\u017eia\u013e prest\u00e1va by\u0165 vodotesn\u00fd.<\/p>\n

\u010co m\u00f4\u017ee \u00eds\u0165 zle pri technol\u00f3gii v\u00fdroby vodotesn\u00e9ho bet\u00f3nu?<\/h3>\n

Za\u010dneme od beton\u00e1rne, kde m\u00f4\u017eeme pou\u017ei\u0165 nespr\u00e1vny recept na bet\u00f3n, nespr\u00e1vne zvoli\u0165 kamenivo, m\u00f4\u017ee d\u00f4js\u0165 k chybe v pomere cementu a vody v bet\u00f3ne, alebo dokonca m\u00f4\u017ee d\u00f4js\u0165 k chybe pri dod\u00e1vke na stavenisko.<\/p>\n

Preprava bet\u00f3nu: V\u00e4\u010d\u0161ina z n\u00e1s \u017eije v ve\u013ek\u00fdch aglomer\u00e1ci\u00e1ch, vieme, ak\u00e9 s\u00fa z\u00e1pchy. Bohu\u017eia\u013e, bet\u00f3n by mal by\u0165 pou\u017eit\u00fd maxim\u00e1lne do 50 min\u00fat od jeho vyrobenia. Z\u00e1pcha trvaj\u00faca hodinu sp\u00f4sob\u00ed, \u017ee bet\u00f3n bude pravdepodobne potrebn\u00e9 vylia\u0165. Na stavenisku sa \u010dasto st\u00e1va, \u017ee tes\u00e1r prid\u00e1 vodu do bet\u00f3nu, aby zv\u00fd\u0161il jeho plasticitu a lep\u0161ie sa ukladalo. To v\u0161etko naru\u0161uje pomer v\/c, u\u017e to nie je n\u00e1\u0161 vodotesn\u00fd bet\u00f3n. Vyliali sme bet\u00f3n, e\u0161te mus\u00edme namontova\u0165 tesniace p\u00e1sy v technologick\u00fdch prest\u00e1vkach. Ch\u00fdbaj\u00fa p\u00e1sy, zvolen\u00fd nespr\u00e1vny typ, nespr\u00e1vna in\u0161tal\u00e1cia, nespr\u00e1vne zvarenie. Ch\u00fdb m\u00f4\u017ee by\u0165 ve\u013ea.<\/p>\n

Ukladanie bet\u00f3novej zmesi: \u010fal\u0161\u00ed krok, kde sa m\u00f4\u017ee v\u0161etko pokazi\u0165. M\u00f4\u017eeme zhadzova\u0165 bet\u00f3nov\u00fa zmes z pr\u00edli\u0161 ve\u013ekej v\u00fd\u0161ky, \u010do sp\u00f4sob\u00ed jeho rozdelenie, cez pr\u00edli\u0161 dlh\u00e9 alebo pr\u00edli\u0161 kr\u00e1tke vibrovanie, alebo m\u00e1me pr\u00edli\u0161 kr\u00e1tky vibr\u00e1tor a nie sme schopn\u00ed vibrova\u0165 cel\u00fa v\u00fd\u0161ku steny.<\/p>\n

Starostlivos\u0165 o bet\u00f3n: to, \u017ee sme polo\u017eili bet\u00f3n, je len polovica \u00faspechu, mal by by\u0165 udr\u017eiavan\u00fd v spr\u00e1vnej vlhkosti a teplote. Ak je pr\u00edli\u0161 such\u00fd, mal by by\u0165 polievan\u00fd vodou, ak je pr\u00edli\u0161 mokr\u00fd, mal by by\u0165 chr\u00e1nen\u00fd pred zr\u00e1\u017ekami, a ak je pr\u00edli\u0161 studen\u00fd, mal by by\u0165 ohrievan\u00fd, aby nezamrzol, ale vytvrdol. Za v\u0161etko je zodpovedn\u00fd \u010dlovek a ka\u017ed\u00fd z t\u00fdchto ch\u00fdb sp\u00f4sob\u00ed, \u017ee bet\u00f3n nebude vodotesn\u00fd.<\/p>\n

\u010co robi\u0165?<\/p>\n

Predpoklada\u0165, \u017ee bet\u00f3n nie je vodotesn\u00fd s\u00e1m o sebe, a pou\u017ei\u0165 miner\u00e1lne materi\u00e1ly, ktor\u00e9 uzavr\u00fa tieto trhliny. Teda vraciame sa k Hydrostopu a k ilustr\u00e1cii, kde je vidie\u0165, ako s\u00fa tieto trhliny tesnen\u00e9. Treba predpoklada\u0165, \u017ee chyba m\u00f4\u017ee nasta\u0165 v etape realiz\u00e1cie a pripravi\u0165 sa na to, ako t\u00fato chybu eliminova\u0165.<\/p>\n
