Before being embedded in concrete, displacement pipes must be secured against lifting in the  unhardened concrete. This can be achieved by the  temporary application of load which, however, will cause additional stress to the  sheathing and the  supporting structure and will hinder the  concrete work. The  better solution therefore is the  anchoring of pipes below the  sheathing. The  strength of the  lifting forces is quite often underrated in practice, especially with  pipes of greater diameters. it  is therefore recommendable to use statically tested anchoring systems. Hydra tie rods are  statically tested and have proven their economical application in practice.
