Filling in Large Holes before Epoxy

[jcgraybeal]

I have 2 slabs of concrete (joining buildings) that were separated with a 2x6 and some 6x6 posts. I have removed the 6x6 posts and the 2x6. I now have a 1.5 inch gap and some 5.5x5.5 inch holes to fill before epoxy.

What is the best way to fill the holes? I assume if I use a bag of concrete mix I will have to wait 30 days for it to cure before applying the epoxy?

I have checked around and can buy epoxy filler but will run about $150. And have to wait to get it shipped.

1. Do I have to wait for 30 days?
2. Hydraulic cement an option?

When you fill a small hole with fast dry concrete you can throw the 30 days out the window. The volume is very small plus the surrounding slab is going to help **** all the water out of it. Should be good to go in a day or two.

You can cap with some clear plastic to check it.

I talked to someone very recently about this on the phone.
