I have a dip in my garage floor. During winter months when the snow melts off of the car, it creates a puddle (right behind car) where I have to sweep it out with a squiggee onto driveway. Depending on the frequency of snow, this might happen several times a week.
Thinking about drilling a (say) 4" diameter hole into the low spot of the dip of my floor. Then as the snow melts, it will slowly seep down the hole and scatter underneath my garage floor.
