We installed waterproofing on the outside of the foam insulation panels at the locations that will be backfilled. The green “Mel-Rol” is waterproofing.
Next, Austin started on building the stem walls. After these walls are poured, this area is backfilled with gravel and then the slab-on-grade is poured.
Every 16″ on center is a rebar that has been drilled and epoxied into the concrete footings.
Our first concrete pour of 2015 – the first floor slab and patios! Here is a photo pre-pour, illustrating the rebar as well as the amount of forming required to create the back patios.
The back patio (on the furthest side from this photo) is approximately 12′ off of the ground level. The bags were filled with gravel and then plywood was constructed as the exterior form for the concrete walls and slab. Here is the patio after the concrete has been finished.
Here is an aerial photo of our property after the concrete pour, taken on January 19th. We are now using the first floor as a staging-area for the materials we have to build the 1st and 2nd floor walls.
As you can see in the photo, we have already started setting the corners in place.
We completed the concrete pour for the basement walls and the 1st floor deck.
The pour had been scheduled for Thursday September 18th, but we had to call it off because on Tuesday night at 3am, my water broke. Our son was born on the 17th – and my amazing husband still pulled off the pour on the following Monday!
Here I am with our one week old baby, standing in front of the freshly poured basement!
Instead of using a select fill material that would need to be compacted, we used gravel, which we then just needed a bobcat to place. We trucked in 7 loads of gravel for backfilling the basement.
This weekend, we had special visitors, my Grandpa, aunt & cousin from Florida. Grandpa was very intrigued and enjoyed talking to Austin about the house.
After completing the backfill, Austin began with laying out the basement walls. He drilled & epoxied rebar dowels, laid the track, and erected the first corner! He has also pre-assembled all the corners and a bunch of the wall pieces so that he can get more efficient production.
The basement is really starting to take form now. All the materials in the center will eventually form the walls! We have received quite a bit of interest from the neighborhood, wondering what the heck we’re building with this Styrofoam 🙂
It took 3 weekends and several weeknights to perform the layout, forming, fastfoot installation, and rebar placement. I am so proud of my husband for doing it all himself.
The footings for the basement are a level 5″ below the finished floor elevation. The footings for the 1st level are purposely not level, instead they are simply 16″-24″ tall. Stem walls will be installed next to bring the foundation to a level finished floor elevation, then the non-structural slab can be poured.
