How To Do a Concrete Monolithic Floor and Foundation

In this article: Fill Calculator and Concrete Calculator This article is an excerpt from the Multitorial: Straw Bale Energy Revealed by Rusty Cline Reinforced Concrete Foundation Design "Build your castle in the air . . . but put a good foundation under it first." RUSTY CLINE Monolithic Definition: "Having a massive uniform structure that does not permit individual variations", according to, Funk & Wagnall's Standard Dictionary. With proper reinforcement this is my foundation of choice for cost, speed and structure. It is also the easiest to convey. When the concrete is poured all together and backed up with enough steel so as not to separate, it is by far the best choice. There are no seams or cold joints unless there is joint reinforcement. There are no precast or per-poured footings. Monolithic: This is the type shown in the animations under weight bearing styles listed above. The steps are as follows:
  1. Forms are set and braced to an elevation established during layout (8" minimum above highest corner) and straight to the string lines on the batter boards plus the width of perimeter insulation. All set for footing foundations.
  2. Dirt or fill (highly compactable 'AB' is recommended for depths greater than 3") is brought in to be spread and compacted to 4 to 3 1/2" below the finished floor grade. (Get Groovy Concrete for better concrete details). Any sub-floor plumbing and electric is installed.
  3. Floor reinforcement or concrete mesh is set. Plus, slab on grade reinforcement must be installed. This should be structure reinforcement calculated for building reinforcement of the upper structure and any column reinforcement. Allow for any seismic reinforcement as necessary or per code for reinforcement walls.
  4. Rebar is set and braced into trenches and another is set 3" below floor line by top of slab (see Reinforcement).
  5. County or City Inspection is made.
  6. Bolt or embed marks are made on the forms.
  7. Insulation is placed along the inside perimeter of the forms.
  8. Termite treatment is done if required or desired.
  9. Slab and footing are poured from a concrete truck all together - no cold joints.
  10. Toe up is installed into the wet concrete - for adobe or straw bale constructed walls.
  11. Bolts and embeds are placed into the wet concrete.
In the Multitorial at this point you will find animations. Here is a sample Calculator as you would find in the Multitorial:
Length Feet Inches
Width Feet
Inches
Depth Inches
You need: Cubic Yards of fill - or: Tons of fill.

All techniques are as lined out above, but the steps change. This is easier if you have a little help.Get Groovy Concrete
