Greblock is a gremial of industrial block producers in Guatemala. They offer two types of blocks: Normado Block and Artesanal Block. The Normado Block is a prefabricated piece used for construction, with features such as low moisture absorption, thermal and acoustic insulation, and high seismic resistance. It is made with specific materials and precise machinery to ensure its quality. On the other hand, the Artesanal Block is handmade without quality standards, resulting in high moisture absorption, low resistance, and easy breakage.

Choosing the right block is crucial, and Greblock provides information and statistics to help customers make an informed decision. They emphasize the advantages of using Normado Block, including thermal insulation, acoustic insulation, and moisture resistance. It is the only block that guarantees seismic resistance. They also explain why customers should avoid buying Artesanal Block due to its lack of quality regulations.

Greblock offers different types of Normado Block, each suitable for different construction purposes. Customers can contact them through phone or email for further inquiries.
