Les joints CORTARTEC MASTERSTOP (swelling), des joints d’\u00e9tanch\u00e9it\u00e9 hydro-expansifs \u00e0 base de bentonite, pr\u00e9sentent un comportement hydrophile. Ils sont compos\u00e9s de fibres expansibles qui peuvent grossir jusqu’\u00e0 16 fois leur taille au contact de l’eau ou de l’humidit\u00e9, ce qui permet d’assurer l’\u00e9tanch\u00e9it\u00e9 des joints dans le b\u00e9ton et de combler les vides, les fissures et les irr\u00e9gularit\u00e9s. Comme ces joints sont hydro-expansifs, il est essentiel de les maintenir au sec au moment du b\u00e9tonnage ; leur application doit donc avoir lieu le plus pr\u00e8s possible de ce moment. Les joints waterstop en bentonite hydro-expansifs s’appliquent facilement par collage \u00e0 la surface du b\u00e9ton \u00e0 l’aide d’un mastic COR POWER pr\u00e9vu \u00e0 cet effet ou, \u00e0 d\u00e9faut, \u00e0 l’aide d’un profil\u00e9 en treillis m\u00e9tallique COR SWELLING clou\u00e9 au b\u00e9ton, \u00e0 l’aide de clous \u00e0 enfoncer manuellement ou d’un pistolet \u00e0 clous. Le positionnement doit se faire au centre de l’armature de renfort du b\u00e9ton.<\/p>\n\t\t<\/div>\r\n\t\t[\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
