This is in oklahoma.
Already talked to the inspector, and he said they allow tunneling.
Not in a crawlspace, talking about tunneling under a slab to replace 10 feet of 3 inch cast iron. The homeowner does not want to penetrate the slab and have to pay me for the repair, then have to get tile work done, so this is the other option. Tunnel under the slab from outside.
Is there any codes anywhere as to what has to go back in? We are going to use what we call flowable fill. Kinda a real soupy concrete mix from what I understand.
But even the inspector was not sure as to any real codes, as to what has to go in as backfill.
Obviously, it has to support the foundation. Anyone familiar with this technique? They use it in texas ALOT. But here, it's not only expensive, but kinda unheard of.
