Building with pallets and clay



The construction of a house with walls made of pallets and clay plaster aimed to build a shelter for batteries and control devices of the energy system, reusing as many materials as possible. We preferred local materials to make a construction with the least possible impact.
It also served as an essay to know the possibilities of construction offered by the local clay that we had obtained in a population about 6km from the farm.



Pallets used, euro-pallet type, were decided by local companies. All have the same dimensions and, once screwed together, constitute the ideal structure for the floor and walls of the house.
In the outer base was used a technique known as "elephant feet", which consists of placing stones around the base of the wall to protect it from water at ground level. A wall of clay always needs good boots and a good hat.


Plastering and finishing:

To perform a comparative study, the plaster of each wall was made with a different mixture: clay + lime + straw + cow excrement, clay + straw + cow excrement, clay + straw + ash and only clay + straw. Adding cow excrement or ash to the clay is known to produce a chemical reaction that increases the waterproofing capacity of the mixture. In total two layers of plaster were applied, the last one only composed of clay and straw. Then they were painted with two hands of muffled lime.



To cover the interior walls we use tetrapacks of soy milk. Being inside of aluminum, it has a good ability to reflect light making it increase the interior luminosity of the house.
