Using natural, locally sourced, raw materials to improve water resilience of earth buildings

Without stabilisation or water resilience measures, earthen architecture is at risk from monsoon rains, standing water, flash floods and humidity. However many low income households are unable to afford additives such as bitumen or cement. The in-field analysis identifies mulch from the Bijla tree as a low cost alternative to synthetic options in improving the quality and longevity of earthen construction across rural Bangladesh.
Earthen solutions can be sustainable, low cost and beautiful, however there is a high level of maintenance required and time invested.
