<p>A tongue and groove connection between at least two plates 1, 2, which together form a foundation plate intended to be fitted between an earth course 4 and a concrete course 5, is provided with members for breaking the capillary effect in the joint and preventing water transport through the foundation plate. To this end, the tongue 9 is of such a height and the groove 8 is of such a depth that between the top surface 15 of the tongue and the bottom 12 of the groove a gap 16 is formed which eliminates capillary forces. <IMAGE></p> |
