  1. D\u00e9capage m\u00e9canique, sablage, hydrod\u00e9capage ou autre traitement de la surface ad\u00e9quat pour \u00e9liminer toutes les parties d\u00e9grad\u00e9es du b\u00e9ton existant et obtenir un bon degr\u00e9 de rugosit\u00e9 superficielle n\u00e9cessaire pour assurer une adh\u00e9rence correcte de la chape coop\u00e9rante au support.<\/li>\n
  2. Apr\u00e8s saturation du support avec de l’eau, mise en place de coffrages parfaitement \u00e9tanches. Il est recommand\u00e9 de renforcer les coffrages en augmentant les entretoises en acier. Adopter des \u00e9tapes de coulage ne d\u00e9passant pas 3 m\u00e8tres de hauteur.<\/li>\n
  3. M\u00e9langer avec un malaxeur \u00e0 axe vertical, \u00e0 grand nombre de tours, \u00e9quip\u00e9 de pales \u00e0 mouvement plan\u00e9taire et de racloir (type IMER MIX 360 ou similaire) selon la proc\u00e9dure de m\u00e9lange indiqu\u00e9e dans la fiche technique du microb\u00e9ton.<\/li>\n
  4. Coulage par simple versement du haut de microb\u00e9ton RINFOR GROUT COL, qui combine la rh\u00e9ologie auto-nivelante \u00e0 des valeurs physico-m\u00e9caniques exceptionnelles et qui permettent un renforcement structurel et une augmentation de la ductilit\u00e9 de la structure. Le microb\u00e9ton doit contenir un tr\u00e8s haut contenu de microfibres m\u00e9talliques (> 130.000 fibres READYMESH MR-200 pour chaque sac de 25 kg de pr\u00e9mix), des fibres synth\u00e9tiques en polyol\u00e9fines READYMESH PM-060 et des additifs cristallisants sp\u00e9ciaux capables de r\u00e9duire le retrait libre et d’augmenter, par un processus d’auto-cicatrisation, la durabilit\u00e9 du chemisage de renforcement. \u00c9paisseur du chemisage de 30 mm \u00e0 60 mm selon les plans structurels. La consommation de produit est d’environ 22,5 kg\/m\u00b2 par cm d’\u00e9paisseur appliqu\u00e9.<\/li>\n
  5. Prendre soin du durcissement du coulage selon les prescriptions d\u00e9crites dans les \u201cLignes Directrices pour la mise en \u0153uvre du b\u00e9ton structurel\u201d du Conseil Sup\u00e9rieur des Travaux Publics.<\/li>\n
  6. Apr\u00e8s un durcissement ad\u00e9quat du chemisage de renforcement, lisser les surfaces avec un enduit \u00e0 haute adh\u00e9sivit\u00e9 RASOCOAT, appliqu\u00e9 en deux couches avec une \u00e9paisseur totale d’environ 2 mm.<\/li>\n<\/ol>\n
