My driveway is pulling away from the garage foundation. What should I
fill this with to keep the moisture (especially during the winter)
from seeping into the large crack. It is about an inch wide this year.
The driveway is only about 10 years old.
Get the concrete super clean
Install the appropriate size backer rod.
Use self leveling polyurethane pavement sealer.
Probably not Home Depot stuff. YMMV.
