Bathroom Addition - V2 | Page 6 | Construction and DIY projects | Forums

That's my plan. Or just put some quarter round or other trim at the base of the wall.

Ran into two issues last night as I started to excavate for the beams:

There's a concrete beam beneath the brick wall - Will likely have to cut this, or pour around it. Waiting to hear back from the civil engineer but I'm assuming that it would be best to remove it.

There's a gas line running plumb through the middle of where I need to run the slab - I'm having the plumber who will do the rough in plumbing come move the gas line so that it skirts the perimeter + 2'

I believe that I could do the rough plumbing myself but don't want to risk it with the concrete being permanent and all.

With the house being built in '55 and a lot of arguments against it I'd rather play it safe. As far as the plumbing goes: did you ever figure out why your drainage was slow? I've always thought that to be inadequate venting.

Yeah, I heard back from my plumber so I'll have him do the rough in. I'm torn on the slab: I'd love to do it myself ($$$) but my wife wants to have it hired out. Best price right now is $3750 but I know better than to take the best price. The next price is around $4500. Still seems absurdly high.

Still no luck with the concrete guys and of course, I'm inherently getting better quality by doing it myself. However, I may have made a mistake.

Because the slab is partially raised, I cut 8" of soil off of the top, dug the trenches, and then started to place the crushed rock and tamp it. Only problem? The sides of my internal rectangle are collapsing into the trenches.

How is this usually done? Cut off the top 8, place and tamp, then cut trenches? This is what I will do for the second section.

Now that I'm where I am, I don't know a good way to fix it. I know for taller monolithic slabs you can build up the interior with woven sand bags. With that said, can I get away with bags of concrete? The woven sand bags are on Amazon but then I would have to go through the labor of filling them so for $3 I can just get pre-filled bags of concrete.

All thoughts appreciated! Hoping that I didn't shoot myself in the foot.
