Do not set a large exterior louver bank directly on raw concrete and rely only on perimeter caulk.
Check
Look under the louver frame for a continuous sill pan/flashing.
Check for turned-up end dams and front drip path.
Verify the pan ties into the wall waterproofing.
Make sure the pan drains to the exterior, not into the wall.
Do not final-anchor the bank until base flashing is resolved.

Say this to your foreman
The louver bank at [location] is sitting on raw concrete with no visible sill pan. I checked the base and drainage path. Do you want a sill pan/end-dam flashing detail installed before final anchoring?
