Water is backing up under the garage door slightly. The pitch is
essentially level outside the door (not pitching away). Water builds
up during rain and comes under.
Regrading/repaving the driveway is out.
I have thought of two solutions. Which one do you guys think is the
Install a saddle for the door to sit on. Cement it down with Liquid
Nails to provide a waterproof seal. This will not remove a small
(1/4") amount of water against garage trim during the rain, but might
keep the garage inside dry.
Cut the cement apron of garage threshold across the width of the door
and put in a metal drain. I have a sump pump right inside the door.
Could drop a pipe to it through the a slot in the slab (and recement
over pipe). This willl drain the water from the garage threshold area
to the sump.
