I have a concrete-pebble driveway that has been repaired. The area
that was cut with a diamond saw needs a bit of help. A few of the
pebbles have popped out along the cut surface and I want to fill those
holes with a cement-like mixture. My problem has been that all the
materials I have tried lack strength and adhesion. Please see attached
photos. Any suggestion as to how I can mix up some "cement" to repair
the voids.
