Upgrading the most widely used construction concrete blocks into a carbon sink, healthy, earthy solution.

For decades, buildings all around Indonesia have been raised using regular concrete blocks (batako). By developing and producing its earthy alternative, baTa(nah)ko, we aim to lower the environmental impact of construction industry.
Indeed, with a very low embodied energy, baTa(nah)ko will strongly lower your development footprint while highly enhancing the healing benefits of your home.

Limestone, clay and lime construction blocks, BaTa(nah)ko

Easy construction technique, strong and durable: Easy to handle, blocks with similar shape have been used for decades, making it an easy alternative for your construction team. With similar compressive strength to the conventional concrete blocks, they raise long-lasting structures.
Fire-Resistant: Naturally resists fire without toxic emissions, enhancing safety in construction.
Non-Toxic and Healthy: Free from harmful chemicals, promoting a safe living environment and wellness.
Acoustic Insulation: Provides excellent soundproofing, creating quieter spaces.
Great Thermal Mass: Retains night fresh-ness to cool your interior during the day. BaTa(nah)ko will help you keeping interiors comfortable while reducing heating and cooling needs.
Breathable and Moisture-Regulating: Allows vapor permeability to manage humidity, preventing mold and maintaining healthy indoor air quality.
Eco-Friendly and Sustainable: Made from highly available local resources, baTa(nah)ko is a low-impact material that’s 100% decomposable and supports carbon sequestration, making it carbon-negative over its lifecycle.
