I need to clear out a crawl space and cement the floor. I can dig it out but it's alot of dirt. If i rented a vacuum excavator could I get the dirt removed in one day?
If you have to ask, you DO NOT have a team qualified to operate the machine. I GUARANTEE, hiring a contractor NOW, will cost less than having them fix the damage when they building collapses after you compromise the foundation. OK, I watched the video. You don't have a CLUE what the term crawl space means. If you remove the dirt, the foundation WILL collapse. Whoever told you the foundation extends 6 feet below the floor CAN'T know that, because they did not EXCAVATE to the bottom of the foundation.
I'n not sure the dirt doesn't have to be there. They backfilled it to support the walls. I'n not sure the block wall can hold the dirt back without the fill in the middle. You need an engineer to tell you that removing that dirt won't make the house fall down. really. Block walls have almost no strength.
