The topic of today’s podcast: Will putting in a Radon system put cracks in my foundation?

Narrator: Well alright Crackman, I understand that a person in Fitchburg, MA has some questions about a Radon system that was installed. What happened there?

Rich: We had a call from somebody who was going to put in a Radon system. He called to ask me if it was going to cause cracks in the foundation floor. Because with the Radon system, what they do is they break a hole in the floor and they put some PVC pipe in like a T, and then they bring it up out of the basement and above the roof with a fan on it to draw that Radon out. He was concerned that it was going to cause cracking in the floor.

Well he called me up because we have done work for him in the past, in fact I looked it up and we have done some floor crack repair for him. His question was, is it going to cause more cracking? My answer to him, especially since he has already had cracks and we had filled it in with a high-grade epoxy material that has some elasticity, that the chances of getting additional cracks were very small. So, he did have it done and he called me back to say that I was right, that it didn’t cause any more cracking.

Now we can take this one step forward and say, would it crack the foundation floor if no work had been done to it? Well the chances are less if there is an expansion joint in the foundation floor which is all lines and a cut because the concrete has a chance to mold. If there is not an expansion joint, no work has done to it, the chances are still very small that something like that could cause a crack, an additional cracking in the floor. It’s mostly the pressure from the water against the bottom of the cement floor that causes cracking or shrinkage of the concrete as it does have water in it that cause crack. Well even if you do it’s not the end of the world if you get a crack in your foundation floor. There’s these three things you’re sure of in life: first, cracks, if anything’s of concrete it is going to crack, and if it does we can repair cracks in concrete floors. If it’s in Fitchburg, or in New Hampshire, Rhode Island or all over Mass., we can take care of it.
