I'm building a concrete shower curb and pan. I built the curb and when I removed the 2x8 forms I notice that I didn't pack the cement all the way to the bottom in some parts:
A bit crumbled and fell out when my wife touched it, but the rest seems very solid. (There is a lot of dust near the curb left over from the install.)
I'm a little north of 200 lbs and I stomped on it and there was no movement or anything.
- Is this a failure? Is failure of the curb imminent (within 5/10/20/etc. years)?
- If it will not fail then how should I fill the gaps? Fill it in?
