In keeping with the recycling theme of the shipping container home, we are starting to build a retaining wall out of used tires. It will take about 3,000 tires to build the 30 ft high retaining wall behind our house.
In an effort to eliminate even more waste, we are using cement bags left over from the first level construction (and hundreds that we collected from trash sites all over the area) underneath each tire to hold the dirt.
Here are some photos of the start of the project, and we will post more as the project progresses.
Our first load of about 200 tires from an auto shop in Rivas
The lower levels of the wall are three tires deep, tapering off to one tire deep at the top
Each row has about 50 tires
Each tire is packed with dirt and weighs about 300 pounds when filled
