Not sure where to put this, but since it deals with concrete and asphalt, this might be the best place.
My neighbor and I share a garage that straddles the property line. It's because her house was the original barn for my property, and it was turned sideways and converted into a two-flat when the owner decided he wanted to have some rental income. Then he built a garage between the two houses. He later decided to separate the two properties, and the property line was drawn between the two houses, through the middle of the garage. That was back a few decades.
Now there are two garage doors on each side, a common area, and each side has a separate driveway about 90' long that goes to the street. The driveway was put in about 7-8 years ago and now needs to be sealcoated.
But in addition to that, there is another issue that we have. The half of the driveway closest to the garage is inclined down a bit. With heavy rain, some water seeps into the garage, mostly on her side. There is some drainage, but it's not great. But in winter it gets worse. Ice and snow melt end up at the entrance to the garage, and seep in. Both our garage doors were frozen solid for a while last winter, and she had a good 6" of ice built up IN her side of the garage. I had about half an inch. Obviously, we're not parking our vehicles in the garage regularly.
We're trying to figure out how to deal with the water/ice build-up at the entrance of the garage. Cutting the asphalt and building a drainage trench is one idea that has some up. But I'm wondering if some of the more knowledgeable guys here have some better suggestions?
Picture shows the entrance of the garage that gets filled with ice and water, mostly during winter.
Of course, thanks to the usual suspects, Neal, Bridge, etc. for any comments of suggestions...
