Spacers
Hydra spacers come with fiber-reinforced concrete stones, in which the spacer has been installed by the constructor. In this version, the distance between the foot and the free concrete surface is 30 mm (DIN standard 1045). This will avoid corrosion stains at the bottom of the ceiling.
Removal of Traces in the Concrete The holes for the anchoring rods which remain in the concrete after the removal of the sheathing can be closed quickly and tightly with plastic plugs. This allows for optimum compliance with all demands on the visible surface of concrete structures.
