basic information

【Features】 ■ The product is self-supporting, which improves work efficiency and allows for a reduction in construction time. ■ Its box-shaped structure eliminates the need for buttresses and back forms, enhancing workability. Additionally, it is suitable for fabric stacking, requiring no skilled labor. ■ The immediate demolding method enables mass production, making it possible to respond even in urgent situations. ■ It has excellent permeability and water retention, promoting the growth of diatoms, which are the starting point of the food chain. ■ The design strength standard is 18N/mm², equivalent to that of masonry blocks. *For more details, please refer to the PDF materials or feel free to contact us.
