Bottom
The sheeting cases can be supplied with  fixed bottoms if required. The design of the bottom avoids deformation during the  grouting of the  concrete. As an alternative, a perforated bottom is available. This version avoids inclusion of air and the  formation of cavities below the  structure.

Fixing Claws
Fixing claws guarantee a perfect connectiona between the  sheeting case and the  concrete. Potential separation of the  sheeting case walls after the  removal of the  reinforcement is impossible. The  fixing claws will be mounted to the  sheeting case by the  manufacturer upon request.
