San Antonio's compressed earth block machine manufacturer AECT

Advanced Earthen Construction Technology (AECT) has been making their compressed earth block machines in southeast San Antonio for over a decade.

The large capacity AECT 5000 is self-contained. It can be and has been used all over the world, at times far from any other source of power. Over the years it has been purchased and used by large institutional builders such as American Indian tribes and governments in the republics of the former Soviet Union. John W. Wright's patent 4640671 and patent 4557681 which Mr Wright shared with Jack L. Elkins are used in its design. Its hopper is typically filled by a full size front end loader.

The AECT 3000 is designed for the medium size contractor. It is a different design from the AECT 5000, though it produces the same size blocks. It is manufactured under the patent of David Lienau 5629033 . It weighs just under 5000 pounds as compared to 9800 pounds for its big brother. It can be loaded by a bobcat or tractor.

The AECT Impact 2001 is the machine for the small contractor or home owner. It is loaded by shovel or bucket. Usually it is set to produce 5 1/2 x 12 x 4.5 inch blocks as opposed to the 10 x 14 x 3.5 inch blocks produced by the larger machines. It is small enough to be hauled by a compact car.

The company also now manufactures a soil mixing machine to ease the process of preparing soil for the block presses.
