During production of cast in situ concrete diaphragm walls, the most important factor, especially to achieve a watertight joint, will be the use of the right stop end elements.

The stop end elements contain the concrete on the lateral side meanwhile they create a particular casting profile that offers a high seal against water infiltration. Stop End Elements are coupled together through special steel shafts even better special O-ring ensure a perfect seal between the areas of the diaphragm.

Stop End Element is made of sheet metal welded and its special profile is achieved by a process of press bending and finally an internal reinforcing structure increases its strength and avoids the risk of deformation.
