This is a cover block that enhances the strength of the main block body with a ribbed protrusion structure.
"Fessel G II" creates a stable vegetative cover foundation by preventing the sliding and flow of covered soil through its vertical and horizontal protrusion structures on the block surface. The rib-like protrusion structure enhances the strength of the block itself. The blocks are enlarged to 0.8 pieces/m², which reduces construction labor and costs through decreased work rates and labor-saving measures, and allows for high-quality revetment design and planning through the verification of mechanical stability.
