CA 2549166

Novel, one-part polymer grout compositions are provided comprising a silanated polymer. The inventive grout compositions can thus be water and/or stain resistant to a greater degree than conventional one-part polymer grouts. In some embodiments, the grout compositions may also have enhanced shrinkage and/or crack resistance, as may be provided at least in part by the inclusion of an amount of one or more fiber fillers. As a result of these advantageous properties, the one-part polymer grout compositions provided herein may find applicability in environments previously contraindicated for conventional one- part polymer grout compositions, e.g., in horizontal and/or damp, or even wet, environments, or in combination with certain tile materials, e.g. water absorbing tile materials.

L'invention concerne de nouvelles compositions de coulis au ciment polymère simple, comprenant un polymère silané. Lesdites compositions de coulis au ciment peuvent ainsi être résistantes à l'eau et/ou aux taches, jusqu'à un niveau supérieur à celui de coulis au ciment polymère simple classiques. Dans certains modes de réalisation, les compositions de coulis au ciment peuvent également avoir un retrait et/ou une résistance aux fissures, comme le permet au moins en partie l'inclusion d'une quantité d'une ou de plusieurs charges. En raison de ces propriétés avantageuses, les compositions de coulis au ciment polymère simple peuvent s'utiliser dans des environnements antérieurement contre-indiqués pour des compositions de coulis au ciment polymère simple classiques, par ex. dans des environnements horizontaux et/ou humides, voire mouillés, ou en combinaison avec certains matériaux pour tuiles, par ex. des matériaux pour tuiles absorbant l'eau.
