Binding of a slit wall in a cliff or stony ground, which is overlaid with softer soil and where a slit is excavated in this softer soil and support fluid is introduced to fill the slit up to its top edge. Pipes are arranged vertically in the finished slit and holes are bored into the cliff through these pipes. Reinforcements or support elements are inserted into the holes and reach up to the top edge of the slit well. Concrete is then filled into the holes and trench so that concrete, trench and pile-shaped concrete block are connected with each other.
