1. Method for the production of a water-stop strip (4 to 21) for building walls in structural and civil engineering, in which a water-stop strip (4 to 21) comprising a plastics profile (6, 8, 11, 12, 15, 16, 18, 19, 20, 21) is produced from extrusions, and is provided with reinforcement rods or strips (1 to 3; 4, 5) connected to the water-stop strip (4 to 21) which run solely at right angles to its length and at spaced intervals, characterised in that the flow from a fishtail die (27) is firstly symmetrically divided in thickness, thereafter the reinforcement rods or strips (1 to 3; 4, 5) are introduced between the layers singly, in periodic sequence with the speed of extrusion, and at right-angles to the length of the strip and to the direction of movement of the layers (30, 31), and then the layers (30, 31) are brought together behind each introduced reinforcement (1 to 3; 4, 5) with the help of a vacuum, and are merged into one body (42) in which the reinforcements (1 to 3; 4, 5) are embedded throughout their entire length by enclosing their ends (4, 5).
