Hello,
For those curious on how to reinforce your sub floor when the contractor cancels two days before your move, ahhh well remeber those days in physics and math when we all said when will I ever use this nonsense well today is the day lol.
I will post pics promise and some supplies lol
1.) 4 cement brick slabs (which weigh as much as I do.
2.) 4 large cement bearing brackets that mount to said block.
3.) I used 4x4 treated and rose wood for strength and errrr and was able to get Home Depot to cut them for me. They didn’t give me a very nice look since they had to use a hand saw.
4.) screws and this electric screw drill gun to save you time. Tools to move the adjustments (borrowed brothers tools).
5.) 60 bright green glow sticks and nice flash light and bubble level thingy.
Oh and most important tool and device you need for this ...::::.:....:::::::: One huge Tonka Dump Truck (the metal version lol).
Oh and lots of therapy since crawl spaces are kinda creepy and use clothes you plan on throwing away.

.
Oh in case your wondering why I had so many glow sticks well lol under my house is a maze literally.
I was afraid i couldn’t find my way out and was gonna be stuck down there forever. So I dropped a glow stick about every 12 inches lol. Yes that’s my weakness.
