My Little Homestead has a new video series that documents each step of construction of Shea’s new earthbag bedroom. At the beginning of this particular episode they explain their favorite soil cement floor method.
They use this method as a subfloor or base for an earth floor (what they call cob). I think with practice and refinement it could create a passable finished floor with a bit of touchup later. Here’s the basic process: 1. Till the floor with a mini rototiller; 2. Moisten the soil with a garden hose and till the soil again; 3. Add 1/2” cement on the surface. They distribute the cement with coffee cans. 4. Moisten the floor and rototill. 5. Add more cement then repeat step 4 one more time. 5. Start at the center and gradually start tamping and leveling the floor. 6. Keep floor moist for several days so it dries and hardens slowly.
