Hello, This is my utility room. I'm wondering how I can fix this? After removing the water heater the HVAC contractor discovered there were holes in the plastic pan, and the cement floor had all but disintegrated. You can barely notice the plywood below? It's ready to give way. One suggestion was to refill with cement and put a new piece of plywood, then put the new water heater on top. The only catch is, that this utility room sits over top another utility room My neighbors. I don't know if any of you live in a condo, but this is something I have to consider before trying anything. I'm trying to get the condo association to cover this since there was no leak in the water heater. If I end up having to fix this, I want to do it right. Can anyone help? Thanks kindly.
