Pvc pipe penetration through wood
I have a radon pvc pipe that is being penetrated through the perimeter joist up the attic, and it doesn't seem that it has too much free space around it. Should I worry about the wood joist contracting or expanding and crack the pvc pipe? I started wondering after I saw how much my hardwood floors were gapping over the winter due to shrinkage. And around the pvc pipe, there's some pink hard substance that looks like cement, probably for insulation purpose.
