Dirt floors make children sick, and 1.4 billion people live and sleep on a dirt floor. These floors harbor parasites, bacteria, and pathogens that children across rural Africa are constantly exposed to inside their homes. Replacing a dirt floor with a concrete floor reduces diarrhea by 49% and parasitic infections by 78%, but concrete is both environmentally destructive and unaffordable to the world’s poor. | Dirt floors make children sick, and 1.4 billion people live and sleep on a dirt floor.

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. 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). 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! | 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.
