The clamping surface has to be:

» free of shrink holes, cracks and loose parts
If necessary please take care of the following preparations:
» eliminate protruding fundamental concrete areas, remove flush with the adjacent areas (cut if possible)
» refill uneven concrete surfaces with waterproof resin-based mortar
» to seal permeable concrete, e.g. to get it water impermeable, you might carry out concrete injections
Your working place has to be clean, dry and free of reinforcements!
