Thanks for all of your inputs...
Here's another pic/.
Yes the problem is from roof run off mainly and also it is uphill on the left side of building 2.
I am planning on putting a 6 inch french drain on the left side(/ see blue line). It is gonna flow the way the arrows show ; and go into an open concrete ditch.This should catch most of the water.The red line is gonna be under the /building.Where the water rises over slab. Another french drain. Its going to continue on out from under building to the right.;;downhill .Then to bed and a /c/leanout.

I am trying to eliminate seepage rain water from rising over slab on building 1. We have a sump that does fine as long as there is power.I need to fix for no power. I am planning on digging a trench ;( red line) well below slab grade and try to make the water drain out from under building 2. And continue out to a cleanout and fill bed.Any ideas would be great! Thanks
