Building with superadobe is a unique process that combines traditional earth construction with modern engineering. At the heart of this building method is the process of filling and stacking the bags which will form the structure of your building.
The Right Mixture
Before you begin filling, it’s essential to have the correct earth mixture. A good mix typically includes a balanced combination of sand, clay, and a small amount of moisture. This creates a sturdy yet malleable material that can easily be packed into bags.
Filling the Bags
Filling the bags is a straightforward but critical step. Using a shovel, fill the bags evenly, ensuring they are neither too full nor too empty. A properly filled bag should be firm to the touch and hold its shape, but still be malleable enough to form into the walls. The tubular bags from the Earthbag Store are ideal as they are designed to withstand the weight of the earth and provide a uniform shape for stacking.
Laying the Foundation
Once your bags are filled, begin laying them out on your previously prepared foundation. Each bag should be placed tightly against the previous one to eliminate voids. The foundation layer is the most critical as it sets the alignment for the entire structure. It’s worth taking extra time to ensure this first layer is as precise as possible.
Stacking the Bags
After the foundation bags are laid, you’ll stack additional layers on top. Each layer should be staggered over the joins of the one below, similar to bricklaying. This overlapping pattern contributes to the overall stability and strength of the structure. As you stack, tamp each bag down firmly to ensure a tight fit and to eliminate any air pockets. Securing the Layers To add additional strength, use strands of barbed wire between each layer. This acts as a mortar, of sorts, providing friction and preventing the bags from shifting. The barbed wire is a crucial component, as it helps to bind the bags together, creating a monolithic structure that is highly resistant to external forces. Stacking the bags is a rhythmic process that gradually brings the shape of your building to life. It requires attention to detail, a steady hand, and a bit of patience. But with each layer, you’ll see your vision rise from the ground up.
Consistency is Key
As you continue stacking, it’s vital to maintain consistency in how the bags are filled and laid. Uneven bags can lead to structural weaknesses and aesthetic irregularities. Periodic checks for level and alignment are recommended as you build upwards. It’s much easier to correct a small error than to adjust several layers of earthbags.
Finishing Touches
Once you reach the desired height with your bags, you can finish the structure with a variety of plasters or renders. These not only protect the bags from the elements but also provide an opportunity to add aesthetic flair to your building. The filling and stacking process in superadobe construction is methodical and rewarding. Each filled meter brings you a step closer to completing a sustainable, durable, and environmentally friendly structure.
And while the Earthbag Store provides quality materials for your project, remember that the true strength of your building lies in the careful, hands-on effort you put into each step of this process.
