gap between concrete driveway and stairs
We've got a chunk missing at the bottom of our stairs going up to the main level of our townhouse. There is a gap between the base of the stairs and the driveway. What can I use to fill the gap? The missing chunk is about 2" wide. The gap is about 3/4" at one end and 1" at the other. It seems soil has washed out beneath the base of the stairs, but so far they haven't sunk.
Should I call a mudjacker or just try stuffing it with some roofing tar paper rolled up? At our previous home I've tried the tarry, asphalt roll, about 3" wide and 1/2" thick, but I think it wouldn't be the right thickness and it wouldn't uniformly fill the gap.
Thank you for your opinion.
