Question 14

It’s cold out and I need to pour concrete. I don’t want to move around too much so I’m just going to stand in one spot…

Answer 14

Don’t do that. You’d create a mountain of concrete in that area which would form very thin cracks in the walls where the layers meet

Answer 15

Those are anchors for the sill plates to attach to in order to install the floor system

Question 16

I got all the way to the top and my concrete form blew out at the bottom…

Needs to be coated with damp proofing product to prevent moisture intrusion

Weeping tile. A void to collect water that drains down the sides of foundation walls/soil

Question 21

After a couple years it LOOKS like my concrete walls are a foot higher than where we graded them…

Answer 21

The backfill settled heavily and might now be sloped toward the house

Question 22

There’s a fuckton of water in my basement window well…this sucks

Answer 22

Should’ve had the guys install proper drainage pipe down to the weeping. Tile at the footing

Question 28

3 lateral pressure causes during concrete placement

Answer 28

1) vibrating
2) cold weather; slower setting concrete
3) rate of pour

Question 29

Can I use large rocks in my backfill?

Answer 29

No. It could scrape the damp proofing, and will create voids when you try to tamp it down
