<p>The system has two shaped stones (1b), where an upper side of the shaped stones includes a downpipe. The downpipe conducts the liquid flowing into the gutter in the gutter direction to right or left side surfaces (4b, 5b) of one shaped stone in the downpipe direction. The right and left side surfaces (4b, 5b) of one shaped stone are designed as curved surfaces. A kerbstone (19) runs along the left or right side surfaces (4b, 5b) of the shaped stones.</p> |
