The Adopress 5000 is a patented compressed earth block machine produced by EcoBlock International. The Adopress is designed to use local materials available in Mexican communities to manufacture the ‘Adoblocks’ and build stabilized adobe housing. The machines are provided to communities via programs from the social franchise programme – Echale a tu Casa – with a payment method aimed to help low income families pay for the product over time.

Block dimensions of 10 x 20 x 40 cm or 10 x 15 x 30 cm
Rate of production (units/hour)
1,500 – 2,200 units/hour
Curation duration (days)
Not suitable for cold climates unless necessary vapor barriers and insulation can be added. On their own ISSBs and CEBs do not hold up well to freeze/thaw cycles and have a low thermal insulation capacity.
The Adopress 5000 produces Adoblocks which are made with soil, cement, cal and/or sand. The blocks are comprised of more than 90% local soil and serve as a natural insulation source and reduces reliance on heating and cooling devices. The machine requires an electric, three phase motor or diesel 10 HP engine. Operation with 3 personnel can achieve daily production (i.e. 8 hour shift) of 1,500 (10 x 20 x 40 cm) or 2,200 (10 x 15 x 30 cm) Adoblocks. Additional dimensions and weight not specified.
Families are trained by EcoBlock International technicians about the operation of Adopress. Echale offers technical assistance from start to finish to self-organized communities in order to promote sustainability after Echale leaves the community.
Unknown. The bricks are made from locally available materials.
Vetted Performance Status
According to the manufacturer, Adoblocks are 30-40% more resistant than traditional fired bricks or concrete blocks. Adoblocks also act as an insulation material due to the acoustic properties of the main raw material used: earth.

Compliance with regulations
Echale requires a minimum of 30 families to express interest in order to take part in the project. Echale's approach involves setting up a local housing committee that holds regular meetings to develop a housing program, interact with other stake holders and replicate a social franchise. By creating this committee, Echale hopes to promote the sustainability of the product and community. Echale works with the National Housing Commission (CONAVI), the Federal Mortgage Trust (SHF), the Houseing Institue of Campeche (INVICAM), and a local NGO Impulsac, however no awards/certifications are listed from these entities. Highest score amongst B Corp honorees for Best for the World 2013. Echale is a GIIRS pioneer, a B-Lab corporation, a Schwab Foundation, entrepreneur, and an Ashoka Fellow.
