Concrete and ICF Walls

Pouring Concrete:

Once the drainage was in place, we were ready to start pouring concrete (as little as possible!), to create the root cellar, and support the bale walls to come.

Here are a few more photos of the process.  First the footers below the ICF walls of the root cellar/basement.  Here's Jean-Paul Downs filling the forms.

Here's the ICF (Insulated Concrete Form) blocks, assembled, and ready to pour.  There are PVC pipes running through the walls for plumbing and electrical service. those to the left are for the solar heating system (much more later), while those to the right are for electrical and phone lines from the existing house.  the plan is for a grid-tied solar electric system with a battery backup.

Jean-Paul and Sean pouring concrete into the ICF forms for the root cellar.

Here the root cellar is poured, the rubble-filled trench has been prepared for the 12" tall by 22" ICF forms to support the bale walls, stacked and ready in their bright blue wraps.

Ready to pour the concrete beam.

Here's what holds the walls up.  Black Locust  is used instead of pressure treated lumber.  12" Thick by 22" wide concrete beam with 2" foam insulation on inside and out.

Now we're ready for the timber frame!
