I have a sidewalk that runs at at 90 degree angle to my driveway.
There was a felt expansion piece where they meet, but it has
deteriorated. I dug out the rotted stuff.
The gap between the sidewalk and driveway is about 3/4" wide. Too
narrow to use two 1/2" expansion strips, but too wide for one 1/2"
strip to fill the gap. I've been unable to find 1/4" strips.
A friend suggested using one strip and filling the reamining gap with
sand. Will this work? If so, does it matter what type of sand I use:
playground, leveling, paver locking sand?
