Hilti Profis - Submerged Hole and Cracked Concrete
We are trying to assess HIT-RE 500 V4 + HAS-U 5.8 M16 anchor for a submerged application into a culvert base.
Profis seems not to allow us to assess using the 'Cracked Concrete' option - we can assess using dry concrete option.
Is there a way we can assess for cracked concrete?

No. PROFIS restricts the concrete condition to what the anchor’s approval covers. If the submerged (water-filled hole) installation condition only allows uncracked concrete, the ETA gives no cracked-concrete design values for that combination, and the software can’t create them.
Options to consider:
- Dewater the holes: If the holes can be drilled, cleaned and set with the water removed (water-saturated concrete rather than water-filled holes), select that condition. PROFIS should then allow cracked concrete.
- Show uncracked concrete: If the engineer can show the concrete at the anchor location stays uncracked under all load cases, the current assessment is valid.
- Check corrosion: For a permanently submerged culvert, HAS-U 5.8 carbon steel is not suitable for durability. Consider HAS-U A4 (stainless) or HAS-U HCR, depending on the water exposure.
If none of these work, contact MOZAECC.ZATeam@hilti.com to review the specific case.
