I did a little searching on the forums and found that putting PEX directly in the trench and then using spray foam is a fairly popular method.
I am getting ready to get started on a Pole barn and then trench to the house. I know, I know, I have had my boiler sitting in my basement for over a year (not hooked up...just sitting there) but time and money.......well y'all understand I am sure.
Anyway, I am thinking about using (4) 1 inch PEX lines running into the house and bringing in a contractor to spray the trench.
1) The boiler/storage will be approx. 6 1/2 to 7 feet higher than the current grade at the house. I would be interested in hearing feedback regarding this height differential. The point of entry to the house WILL be the lowest point of the entire trench run.
2) I am thinking about having 2 inches of foam surrounding PEX lines. The spray foam guy has a $600 minimum and my trench will be approx 75'. I believe that I can get him to do the run w/ 4 inches of foam and still be within the minimum. I am wondering if I need to or should lift the PEX off of the bottom of the trench prior to spraying. Any other thought suggestions?
I know that I have very expansive soil but I dont know if that really matters in relation to the project.
As usual....any input, thoughts, suggestions are appreciated
