I have a seam between a blacktop driveway and a concrete wall where all of the caulking material is coming loose.
The concrete/asphalt gap is like 1/2" and the seam is 8 feet long. Behind the seam there is a fairly large space in the dirt, consider a cylinder 3/4" in diameter the length of the seam.
Any ideas what I should caulk or seal this gap with?
Thanks.
