Stuff is pretty cool.
Mix it and it sets up in a few minutes.
You can mix it thin to let it run into the crack and it sets rock hard.
Get at Home Depot or Lowes in small container.

I think this is prolly the stuff I have. Contains silica and, basically, lime-cement. Says it fixes leaks. I was just skeptical. I'll try it. It says to wet the area, mix and apply.
