A flashing and drainage system for use in cavity wall construction, including a flashing member is sized and shaped to be received within a cavity of the wall and over a base member. The flashing member includes a lower flashing portion and an upper flashing portion. The system includes a water permeable body disposed on the flashing member including a plurality of weep tabs extending on the lower flashing portion and spaced apart to correspond to weep holes formed through the wall and a plurality of porous bodies positioned on the upper flashing portion. The water permeable body has a porosity sufficient to permit water to pass therethrough but substantially insufficient to permit mortar and debris to pass therethrough.

L'invention a pour objet un système de solin et de drainage pour la construction de murs creux comprenant un solin dimensionné et configuré pour être logé dans une cavité du mur et sur un élément de soubassement. Le solin se compose d'une partie de solin inférieur et d'une partie de solin supérieur. Le système comprend un corps perméable à l'eau posé sur le solin et comportant une pluralité de jupes s'étendant sur le solin inférieur, écartées les unes des autres pour correspondre à des barbacanes pratiquées dans le mur, et une pluralité de corps poreux posés sur le solin supérieur. Le corps perméable à l'eau présente une porosité suffisante pour permettre à l'eau de le traverser mais sensiblement insuffisante pour permettre au mortier et aux débris de passer à travers.
