Epoxy vs. Polyurethane Crack Injection - how to choose?

This is #014 episode of the 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 between PU and EP resin to inject the crack. Some key indicators will help you to understand the real necessity, this only one step far away from the right resin to take. 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. Have you heard of elastomers and duromers? Do you know what is the main factor playing its role in changing the viscosity on the job site? Can you compare the viscosity and be sure to take the best one (the resin) in a given situation? Do you know how you can easily and really fast remove the covering epoxy paste after the injection is completed? Make sure you stay till the end (this episode is shorter than usual so it's easier to do that :) ) so you get the details. If you ever wanted to take full advantage of using epoxy resin, this episode is just for you. I also mention the injection pump nad packer type so that you can run your injection game in line with the best industry practices. The best is, most of this information I have collected for you directly from a few Technical Data Sheets of PU and EP groutings. Of course, I do reveal some tips taken from my injection applicator company like what is the point in using a nail when attaching the surface packer? If you are like most people, you may have a little problem with straight answering the question of why we drill holes when preparing for polyurethane injection whereas it seems to be recommended to use surface packer (hint - no drilling) when using epoxy resin? I hope you will like the idea o a short technical episode like this. If so, I'm waiting for your questions about the next ones that are needed.
