Le mortier de ciment standard est poreux et sensible \u00e0 la p\u00e9n\u00e9tration de l'eau. Bien qu'il offre une certaine r\u00e9sistance, il n'est pas intrins\u00e8quement imperm\u00e9able.

Pour les angles et les d\u00e9tails, utiliser un tissu d'armature noy\u00e9 dans le mortier. Appliquer la deuxi\u00e8me couche alors que la premi\u00e8re est encore collante afin d'assurer une liaison monolithique. \u00c9viter les joints froids.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Le mortier standard est-il imperm\u00e9able ?<\/h2>\n <\/div>\n

\n Le mortier d'imperm\u00e9abilisation \u00e0 prise rapide est un m\u00e9lange de ciment modifi\u00e9 par des polym\u00e8res qui durcit en 15 \u00e0 30 minutes. Con\u00e7u pour les r\u00e9parations d'urgence, il stoppe instantan\u00e9ment les fuites actives sous pression dans les piscines, les sous-sols, les canalisations et les r\u00e9servoirs d'eau. Ses propri\u00e9t\u00e9s de durcissement rapide minimisent les temps d'arr\u00eat tout en maintenant une int\u00e9grit\u00e9 d'\u00e9tanch\u00e9it\u00e9 \u00e9lev\u00e9e. <\/div>\n <\/div>\n

O\u00f9 le mortier imperm\u00e9able est-il le plus souvent appliqu\u00e9 ?<\/h2>\n <\/div>\n
\n Le mortier imperm\u00e9able est essentiel pour les zones soumises \u00e0 une pression ou \u00e0 une exposition constante \u00e0 l'eau. Les principales applications comprennent le mortier imperm\u00e9able pour les piscines et les r\u00e9servoirs d'eau, le mortier imperm\u00e9able pour les cabines de douche et les pi\u00e8ces humides, les fondations souterraines et les sous-sols, les ponts, les structures marines, les balcons, les terrasses et la r\u00e9paration des fuites dans le b\u00e9ton. <\/div>\n <\/div>\n
