Circular coir log with invisible planting holes
An excellent natural tool for shoreline toe protection!
BioD-SuperRoll™ circular coir logs are completely biodegradable and do not contain any synthetic materials to harm wildlife.
RoLanka’s BioD-SuperRoll™ 12 is a 12-in diameter circular shaped coir log with pre-formed invisible holes for planting and anchoring. RoLanka’s BioD-SuperLog™ coir super log is a hybrid of the coir log (BioD-Roll™) and coir block system (BioD-Block™) with pre-formed holes for planting. BioD-SuperRollTM 12 is made from cleaned mattress coir fiber uniformly packed into 12 in (30 cm) diameter net made of bristle coir twine. The outer netting in the coir log has eye size of 2 in x 2 in (5cm x 5cm). The outer net is knitted with 90 lbs. (400 N) strength machine spun bristle coir twine. There are two sets of invisible pre-formed planting holes (vertical and 45o angle) in each 10-ft. long roll. The invisible holes are covered with coir fiber plugs with 12 in. (30 cm) spacing. The places of invisible plugs are marked with visible markings and twine loop for easy removal of the coir plug. One end of the circular coir super roll comes with a pouch from the netting to facilitate sound connection between two rolls.
