It’s nice to see it been done right, you have been in this game a longer than me so will of seen a lot more then me, but the amount I’ve seen where they just get concreted in or even back filled with clay under a house floor is shocking, I did one a few weeks back in a little utility and they were complaining about the smell, when I ripped it out someone had used 4” perforated land drain and backfilled it with rubble, and these people get paid for that ?
