The Hydraform block manufacturing process requires no block baking and is cold-processed. Blocks can be made on site, reducing transportation costs and energy. The raw materials used are locally available near the site, for example excavated soil, fly ash (raw coal waste), quarry dust or other possible options. An appropriate mixture is created using a minimum of cement. Blocks have low intrinsic energy and are thermally efficient, resulting in energy and cost savings Hydraform interlocking masonry is largely dry stacked and uses a minimum of cement and sand in the mortar. The blocks have beveled edges and an apparent brick finish thus avoiding the use of plaster or a minimum of plaster, if necessary. Thus, Hydraform manufactures nested blocks and the resulting masonry makes it a Green Building Facilitator. Hydraform technology achieves appropriate ranking points. If you are thinking about an environmentally friendly building, need building materials, or create a company eligible for carbon credits under the CDM, these blocks are eco-correct!
