It is a rare thing to have a photo of myself when I am the one usually taking all of the photos. I have to ask to have my picture taken. Many of you know Allen from following our blog. With Arron taking the photo this time. Mary is able to be a part of this blog in a new form. I insisted on my picture being taken because we are on scaffolding. I am not usually one that likes heights. Especially when walking on a narrow 2 x 10 board.
We are focusing on the kitchen walls now that the exterior glass bottles are roughed in. The mixture is an earthen cement. It is the same mixture that we use for the glass bottle bricks. A combination of cement, sand, clay, and water.
We lay out roughly a 3 inch layer of mud and then Allen putts in the bottles. Putting in the bottles is not as easy as it looks. I have tried it and it takes me forever to do it.
Once the bottle is put in the mud it has to be leveled with it's self and to the bottle next to it. This is to prevent the bottle from slanting and in helping to keep your row level.
The bottles also need to be leveled up and down as well. Otherwise by the time you get to the top you could have a slanted wall. Building with bottle bricks has been a really different experience. Allen learned a lot from when he put in the bottles for the bond beam. He took what he learned there and has been applying through trial and error on our kitchen walls. As long as you keep an eye on how the wall is progressing you can catch minor errors and adjust the next row of bottles to help fix that error.
I have to give Allen a lot of credit here. He has done a marvelous job on these kitchen bottle walls. He has built a straight wall. Has remembered when to put in all the electric lines, pipes and steel bars for hanging the cabinets with. And Allen has gotten really fast in leveling the bottles. By the time I get a mixture of mud made he has the previous bottles all laid out. Leveling bottles may seem easy. It doesn't look all that complicated in the photos. IT ISTN'T. You are working with a round 2 1/2 pound plastic bottle and each one can be a different shape. You have to level each end of the bottle because most of the plastic bottles have a curved shaped in the middle. By the time you get one end leveled to the other bottle it can throw off the leveling of the whole bottle and the other end. Each bottle needs to be leveled 4 times. Patience is a must when learning this.
One may ask, Well, How did you learn this? Good question. There are no books on doing this. We learned from looking at photos of the buildings built in the 3rd world countries. And from just doing it. We took this idea of building with compacted water bottles and used this idea in our project. Sometimes it just takes the guts of doing it to make it work.
The advantage of building with compacted bottle bricks is a really strong wall that will add thermal mass to your building. This means better regulated temperatures in your home. Our earthship is all about thermal mass.
I took this photo to show that Allen is now up in the rafters in putting this bottle wall up. He has to duck in-between the rafters now. The lights that you see are LED lights that Allen made himself. They are temporarily placed there so we could see when we have rainy weather outside. They will eventually be placed recessed within the ceiling.
We have so far put up 27 rows of bottles. When we first estimated how many rows that were going to be needed we figured on 30 rows for the shortest part of the wall. The ceiling gets higher going from the back of the front of the Earthship. Allen figures that we have two more rows for the back part of the wall and then we will be at the ceiling.
