This week's story is all about...

This week we poured the slab for the 1st floor (that's the one that goes directly on the ground) in the north house, and we did a few other things.

Water level

Sorry if I'm asleep here but could you describe that principle. I imagine a mark on the tubing the water will reach .... and it's rotated from a central point to various points on the walls.But why halfway up the wall if for slab eveling ... and is the cement poured so dry it won't self level.Thanks

I imagine a mark on the tubing the water will reach .... and it's rotated from a central point to various points on the walls.: But why halfway up the wall if for slab leveling ... and is the cement poured so dry it won't self level.: ThanksThe process starts with a mark on the wall that becomes the base point. The water level is used to transfer that mark to many other points in every room. Then these points are used to set the spikes.The marks are placed at a comfortable height for the guys. Down low on the wall requires too much stooping and it is hard to sight accurately. Concrete does not self-level very well. If the final floor covering were to be carpet, it might not matter much. But a tile floor wants to be level or else the unevenness will be very apparent. I had that problem with a project I did at my house in LA, and I was not pleased.
