#014 episode of Concrete Injection Made Easy podcast.

And since it’s a concrete injection podcast, I have a question: what do we use most often on our job sites to inject into the cracks?
Today's episode is my solo show explaining how to choose the right resin to inject the crack.
We’ll look at the main similarities and key differences and which are used when. I’ll give you an insider’s take on my experience using both.

Make sure you stay till the end (this episode is shorter than usual so it's easier :) ) so you get the details. 
I also mention the best injection pump nad packer type to use both solutions.

If you ever wanted to take full advantage of using epoxy resin, this episode is just for you.
