Compressed Earth Block (Adobe)

The Compressed Earth Block (Adobe) Project was started to produce a quality, traditional building material for use by colonia residents and the general public.  Adobe has been used as a building material in the southwest for centuries, and can be used effectively today to increase the energy efficiency of a structure.  Adobe structures are very attractive and durable.  The Colonias Development Council is producing a type of adobe that is partially stabilized with approximately 3% Portland Cement and is compressed using a hydraulic press rather than sun-dried.  This production method results in strong, water resistant blocks that can be laid immediately.  The soils we are using are from southern New Mexico and are a combination of sand, clay and silt. Semi-stabilized compressed earth block does not necessarily require stucco or other finishes- the blocks are resistant to weathering and water. We can also make a stabilized block with adequate advance notice.  Adobe blocks can be used for homes, fences, landscaping and other purposes. 

Adobe Block Specifications

1. Blocks measure 10” x 14” X 4” thick.  We can also do a special order of 3 ½” thick blocks with adequate advance notice. 

2. Blocks have been tested to meet New Mexico earth building codes.  Blocks exceed the minimum compressive strength of 300 pounds per square inch (psi) and the minimum modulous of rupture of 50 pounds per square inch (psi).

3. Blocks are uniform in size, making them easier to lay.  This will result in savings of time during construction.   

4. Blocks come stacked on shrink-wrapped pallets, which are convenient for delivery.  Each pallet holds 48 blocks and weighs approximately 1 ton.  The pallets can easily be moved with a forklift and the shrink-wrapping provides protection for the blocks. 

5. Each block weighs approximately  40 pounds. 

Production Process

1. Soils are run through a sieve to remove clumps, rocks, and vegetation.

2. The soils are mixed with a small amount of Portland Cement and water in a large mixer.

3. Soil from the mixer drops onto a conveyor belt and is carried up to the hopper on the block compressor.

4. The soil is compressed to produce the final block.

5. Blocks are stacked on pallets, wrapped, and are ready for transport.                         

Purchasing Information

Blocks are priced at $1.10 each- this may seem more expensive than some other blocks on the market, but these blocks are somewhat large than other available blocks.  You should take this into account when comparing block prices. 

Blocks can be picked up at our site or we can arrange delivery.  Shipping charges are in addition to the price per block, and depend on distance, number of blocks, and other factors.  Please call for information. 

We can negotiate a lower price per block on orders of over 5,000 blocks.
