A market for cheap and sustainably produced building materials exists in Bangladesh and helps to solve issues around housing, employment and the environment in that country.


Demonstrate that Compressed Stabilized Earth Blocks (CSEB) can be produced profitably, and bring actors from different sectors together to spread CSEB in Bangladesh.


Building Pioneers produces Compressed Stabilized Earth Blocks (CSEB), an affordable and high-quality building material.


Worldwide, one billion people live in inadequate shelters that offer weak protection against fire, floods, cyclones, heat, cold, insects and moulds. CSEB achieve up to 25% cost savings compared to conventional brick walls. At this lower price, more people could afford adequate shelter — millions in Bangladesh alone.


Unskilled people in rural areas have little chances to escape poverty. Building Pioneers empowers unskilled labourers to produce CSEB as micro-entrepreneurs. Building Pioneers thereby strengthens one of the most vulnerable groups in society and reduces rural migration.


CSEB reduce CO2-emissions by 75-90% compared to fired clay bricks and prevent deforestation for firewood. This is because CSEB do not need to be cured in kilns.


Compressed Stabilized Earth Blocks are well known as a low-cost and green alternative to conventional fired bricks. They are strong enough to easily support one and two story buildings, are much cheaper than fired bricks, and do not need to be cured in kilns, which makes them eco-friendly. CSEB is a proven technology that has been utilized for decades in more than 30 countries, including USA, South Africa and many developing countries.

High quality

CSEB withstand fire, floods, cyclones, heat, cold, insects and moulds and outperform other building materials such as bamboo, corrugated iron sheet and adobe in terms of strength and durability.


Compared to fired clay bricks, CSEB provide similar customer value but are up to 25% cheaper per area of wall constructed.


CSEB reduce CO2 emissions by 75-90% compared to fired clay bricks and prevent deforestation for firewood.

A proven technology.
