BioD-Block™ is a coir fiber block system consisting of a densely packed elongated mattress coir fiber block attached to a bristle coir woven fabric. Coir fabric is tightly wrapped around two block sizes; 12-in tall, 5-in thick block and 16-in tall, 9-in thick. Both block sizes come in 10-ft long coir blocks. The fabric is connected to the coir block on three sides leaving the other side open to fill with dirt. Each coir block has a female and a male end. These male and female ends in BioD-Block™ create a strong and easy-to-handle connection, providing an excellent face to the soil layers
