Raw materials used

Earth, Sand, Cement

Recommended water content (ratio)

6 – 10

Induced pressure (Mpa)


Power source

Gasoline fueled engine with manual controls.

And Gas fueled engine for the automatic control.

Finished unit dimensions

10 x 20 (adjustable) x 30 cm

Rate of production (units/hour)


Curation duration (days)


Suitable climate

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.

Design Specifications

Design specifications::

  • Production Rate: up to 2 blocks per minute.
  • Block Size: 10x20x30 cm (width adjustable to 5cm)
  • Engine: 6 HP gasoline-fueled engine
  • Controls: Manual
  • Hydraulic Components: Prince, Barnes; available worldwide
  • Hydraulic Oil Filtration: 10 microns
  • Pressure to Block: up to 10 MPa
  • Single axle for highway transportation
  • 6-10% water content

  • Training not required but suggested by the manufacturer

Product Schematics

Technical Support

The manufacturer offers consultation, training, and project management by contract and will train a customer to use the machine if they come to their facility in New Mexico, USA. A trained general technician can most likely repair the product.

Replacement Components

Spare tires, wheels, and axles are available with purchase.


The life span of the machine is directly proportionate to the abrasiveness of the dirt used for compression. EarthTek estimates 50,000 - 500,000 blocks/life. All machines have a 1-year warranty.

Manufacturer Specified Performance Parameters

Performance expectations: Reliable, inexpensive engines, simple hydraulic and control systems, able to use a wide variety of soils to build homes, barns, storage sheds, fences, retaining walls, and more.

Vetted Performance Status

The only vetting performed is through customer experience and feedback.Interview with manufacturer


Blocks require specific material amounts and ratios to ensure proper strength and durability values. Water content, clay content, and sand content are important values that need to be evaluated during construction to avoid accidental failure of the structure.

Complementary Technical Systems

A 1.5 or 3-meter gravity conveyor belt can be purchased with the machine.
