I've had similar problems when my worker didn't have the correct build ability for their race. (Human = Repair human, Orc = Repair orc, etc)

Make sure at the top of the unit page under Abilities the unit has the right Repair ability to build with.

One possible solution would be to trigger the mines. There is a unit enters X of unit event one can use. Will need a bit of JASS knowhow to be leak free.

You can also use RegisterUnitWithinRange 1.3d to trigger the mines. It's a pretty effective GUI system for this use case, if you're don't know much about JASS.
