How long do compressed earth blocks last?

Buildings built with earth blocks can last for centuries.

What sizes are earth blocks available in?

Earth blocks can be made in a variety of sizes, between 4” x 12” x 2”, all the way up to 10” x 14” x 4.5”

How do you make compress earth blocks?

Compressed earth block machines, like AECTs, produce between 240 and 480 blocks per hour. The fabrication process uses minimal electricity or diesel fuel.

What soil composition is best for compressed earth blocks?

Most soil types will work for earth block construction. Some clay should be included in the mix - between 10 and 30%, depending on whether the blocks will be stabilized or not. Organic material will not compress and should be avoided - simply taking soil from at least a foot underground will help you avoid this.

Learn about Compressed Earth Blocks

Compressed earth blocks are a manufactured construction material that is natural, innovative, and sustainable. Earth blocks are usually made with soil from the building site, mixed with clays and aggregate for stability.

Mixed materials are placed in a mechanical press and can be made in just a few days. They need to dry for between one and four weeks before they can be used. Once dry, they are water-resistant and act like cinder blocks or brick.

Customers need to choose between “stabilized” or “unstabilized” compressed earth blocks for their projects. “Stabilized” means that 8% of the mixture will be composed of cement, lime, or fly ash. Stabilizing improves water resistance and hurricane protection.

By using all natural materials, compressed earth blocks are low to zero carbon emissions and low embodied energy.

Concrete and rebar columns can be combined with earth blocks for extra protection and seismic resistance in earthquake-prone regions.
