    La construction d’un parking enterr\u00e9 \u00e0 Choisy le Roi n\u00e9cessite de g\u00e9rer les eaux souterraines afin d’\u00e9viter la fissuration de la dalle b\u00e9ton. L’objectif est de limiter la pression hydrostatique sous le dallage en s’affranchissant de la r\u00e9alisation de tranch\u00e9es drainantes et de fosse de relevage. Il est donc pr\u00e9vu, en cas de remont\u00e9e de nappe, de capter et r\u00e9partir les eaux avec un g\u00e9ocomposite de drainage et de rendre le parking inondable via des \u00e9vents.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    Afin de r\u00e9partir les sous-pressions de mani\u00e8re homog\u00e8ne, et de diriger les eaux vers les \u00e9vents r\u00e9partis sur toute la surface du dallage, Maccaferri a propos\u00e9 un g\u00e9ocomposite de drainage de type TerraDrain M1101. Ce g\u00e9ocomposite isotrope est parfaitement adapt\u00e9 \u00e0 cette application car il peut drainer dans toutes les directions. Il est constitu\u00e9 d’une \u00e2me drainante en monofilaments extrud\u00e9s formant un g\u00e9omatelas, avec de part et d’autre un g\u00e9otextile de s\u00e9paration-filtration prot\u00e9geant l’\u00e2me drainante du colmatage par les fines. La mise en oeuvre d’un g\u00e9ofilm sur le g\u00e9ocomposite prot\u00e8ge ce dernier de la laitance du b\u00e9ton. La surface plane du g\u00e9ocomposite permet d’obtenir une \u00e9paisseur de b\u00e9ton constante lors du coulage de la dalle. <\/p>\n

    Les caract\u00e9ristiques techniques des produits de la gamme TerraDrain sont issues d’essais r\u00e9alis\u00e9s dans des laboratoires accr\u00e9dit\u00e9s, attestant de leur qualit\u00e9 et leur performance, et permettant de pr\u00e9dire leur comportement \u00e0 long terme. Maccaferri a dimensionn\u00e9 le TerraDrain M1101 selon les conditions sp\u00e9cifiques du projet et selon la NF G38-061, relative au dimensionnement des syst\u00e8mes de drainage. La capacit\u00e9 drainante \u00e0 long terme du TerraDrain M1101, sous le poids de la dalle de 13cm et de la circulation, lui permet de drainer efficacement les eaux vers les \u00e9vents tout en limitant la pression hydrostatique afin de pr\u00e9server la dalle, et ce pendant toute la dur\u00e9e de vie de l’ouvrage.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
