Compressed Earth Block Sealant and Stabilizer

Block-Seal™ compressed earth block sealant CEB Sealant :

Blocks that are produced by most compressed earth block machines are significantly more dense and stronger than those produced by simply using water during the compression process of making compressed earth blocks.

Now, compressed earth blocks can be made even stronger and more weather-resistant by simply adding Block-Seal™ to the soil while making the blocks. Shown in this photo, the block on the left was treated with Block-Seal, and on the right, only water was used in the production of the block.

The compressed earth blocks CEB were then left in the open air and, after a single rainstorm, the untreated block had been severely damaged. Block-Seal™ compressed earth block sealant is an excellent additive for all types of soil used in the manufacturing of blocks using compressed earth block making machines. Block-Seal™ compressed earth block sealant CEB Sealant, not only helps with the soil matrix but also decreases the materials permeability. Once the blocks are finished they may be left natural or painted. Block-Seal™ is treated with UV inhibitors to help reduce natural degradation of the compressed earth blocks.

Another advantage to using the Block-Seal™ compressed earth block sealant CEB Sealant, for your compressed earth blocks is that the same material used to make the blocks can also be used as a bonding agent between your blocks. This simplifies the operation for you will only need, Block-Seal™ compressed earth block sealant, water and the method by which to produce your blocks.
