[TheForge] OT: My floor is poured: the saga

[Andrew Vida]

Concrete company plant manager came yesterday and the outcome was good.

They will foot the bill to have a 4-6" thick cap of a finishing mix 
poured atop the existing slab.  They will provide finishing, pumping, 
the whole works.  The one caveat is that I first get the walls up, which 
will serve as the form to which they will strike lines for the grade, 
and so forth.  I am thinking I will affix 1x4 below grade for a cast-in 
perimeter drain and box off the drain pipe to keep form a small well for 
water to gather and exit.

This bit could work out rather well.

The real trick now will be getting the walls up.  Plant manager said he 
will try to get some block masons in touch with me.

My idea is to lay 1/2 or 1/3 cap blocks in a doubled manner with 8" 
space between and fill with concrete or  grout.

At the bottom where pressures are high, ever other block would go 90* to 
the wall and act as a tie to prevent a blowout.  Rebar atop each 
course.  Should be plenty strong... 16" thick wall.  Cap them off and in 
the space between the top of the cap and the bottom of the existing 
footing, pack in hydraulic cement, which will expand and thereby take up 
the load.  Hydracide the outer surfaces, put in drains and backfill.

Anyone see any holes in that plan?
