Switching from dirt to a concrete floor has a huge positive impact. More than 1.8 million people are killed by diarrhea each year, but a hard floor can reduce the risk of childhood diarrhea by 49% and parasitic infections by 78%. In addition to diarrhea, non-dirt floors improve malnutrition, asthma, and pneumonia incidences.

In 2022, Terra Firma began building floors in Guatemala and joined the initiative 100,000 Floors to Play On with Habitat Guatemala and Cemento Progresso.
