The transmission of vibrations emanated by rail vehicles is reduced by fixed tracks on floating bearings. The Egcodorn® DND shear force dowel is recommended for the coupling of the dynamically stressed joints.
Coated metal water stops have been established to be simple and secure solutions in sealing construction cold joints. However, in the event of unanticipated joint movement, late shrinkage or ground movement, the primary seal can become compromised and crack injection may be necessary to seal the joint.
Expansion joints in concrete structures are particularly complex and cumbersome, from the design and planning stage all way to execution in the field. Whenever the transmission of transverse/shear forces in combination with structural waterproofing is required, the task becomes even more daunting.
