75% of Rwandans and 70% of Ugandans live on dirt floors, which cause poor cognitive development, infectious disease, and malnutrition in kids. A clean floor has been shown to reduce diarrhea by 49%, parasitic infections by 78% and improve cognitive development by 36%. However, concrete is prohibitive at 300+ USD for a 20 square meter home. 1.4 billion people still live on dirt, and have no option for clean, durable, and affordable floors. | |||

Earth Enable is a Research & Development partnership and addresses this problem by installing sustainable and affordable earthen floors that have 90% fewer carbon emissions than concrete, and are also a third of the price of concrete. | Earth Enable is a Research & Development partnership and addresses this problem by installing sustainable and affordable earthen floors that have 90% fewer carbon emissions than concrete, and are also a third of the price of concrete. Earthen floors are waterproof, easy to clean, abrasion resistant, and beautiful. They are made with a mixture of compressed earthen materials – rocks, sand, clay – and are then sealed with our proprietary plant-based drying oil. Our floors are not only a third of the price of concrete; they also use 90% less embedded energy. These floors are made of compacted earthen material (a fine sand and clay layer is troweled onto a compacted rocky soil that also has lots of clay content), and sealed with a proprietary linseed-oil based varnish that turns into a resin when dry (see process below). Earth Enable provides an affordable alternative to dirt floors: locally sourced, earthen floors that are 75% cheaper than concrete. While our product has found a huge market of families who are eager to upgrade their homes, we have significant challenges that we are eager to partner with teams of students to address! | ||

There are four subjects students can contribute to in the minor:
- Resin Hardness
- Resin Curing Time
- Floor Color
- Stabilization of the floor
