My garage was built in 1942.
It never had a floor drain in it.

Is there a standard way to add a drain?

Cut the slab with a diamond saw, dig a trench, lay the PVC, backfill, repour the
concrete. Tis a lot of work, especially if the slab doesn't have the proper
slope to bring the water to the drain.

If that's the case, you break up the entire slab with a jackhammer and repour
after the drain is installed.

The other question is where the drain empties. You'll need to find a storm drain
or sanitary line...
