We have just bought a house and with the first rain found that there is a slight slope from the garage doors inward. I bought a couple of bags of asphalt from the local do it yourself store and build a small dam across the lenght of the overhead door with the top of the dam inside of the door. There is still a slow seepage of water thru the asphalt.
Thinking of adding some more asphalt so that there is more oa an slop out towards the curb. Also fell that I need to add some type of liquid sealer to flow down in to the cracks and crevices of the dam and seal it better to the old floor.
Need your surgestions on what type of sealer to use and wher I might purchace it. I will be doing 2 doors.
