Cracks in Garage Floor Near Door. Worry?
Hello. My garage is below grade and I had been getting lots of rain under my garage door the past few months. I replaced the weather seal at the bottom and (more effectively) rerouted my drainage spout. Today I found that the garage floor in the corner under the door has thin crack. My garage floor IS my foundation (my house is built on top). Can I clean and patch this crack or is it panic time? Thank you so much for any advice.
