Alternative Construction - Earth Bag Kitchen
Brand new polyethelene bags (grain sacks) and tubes are filled with adobe dirt
and pounded into rock hard "adobe bricks" to make structural walls for
buildings and fences. Our first building experience with this style of
construction was accomplished by building a kitchen to compliment the tire
house and to learn first hand these building techniques before building
classrooms at the Technico Maya school project. First, a foundation of gravel
filled tires was laid in a trench. Heat stressed bamboo stakes were then added
to tie the foundation into the ground as well as lock the first course of
grain sacks to the tire foundation. Barbed wire is laid in two strands between
courses to keep the grain sacks from slipping on each other and to add tensile
strength to the structure. Arch supported doors and windows are blocked out
using wooden forms. A concrete bond beam was poured on top of the walls to
lock the top. Door and window forms were then pulled, dirt bottle columns were
built for extra security, and a flat concrete roof was poured on top. To date,
our next step is to pull the roof forms. Once the forms are pulled, we will apply
interior and exterior finishes, counters, and a wood stove. A cool-storage pantry
for fruits and vegetables will go in the back corner of the kitchen where it meets
the tire house. We will add a rain harvesting system to the out door patio and
solar heated shower. The wood stove will heat a water cistern on the roof, also
connected to the shower.
Earthbag construction was inspired by the work of Nader Khalili.
