The barrier creates an underground enclosure leaving approximately 2” above ground to force rhizomes to try and jump the barrier. Barrier containment involves digging a 28” deep by 12” wide trench where a 30” tall 80 mm HDPE rhizome barrier is installed. The difference in cost in negligible, so we suggest going with the higher level 30” deep barrier. HDPE, as a root barrier, also comes in 24” or 30” depths. As we have seen the lower thicknesses fail in the past, we always suggest going with the 80 mm thickness. ![]() This comes in 40,60, and 80 millimeter thicknesses. The best option is High-Density Polyethylene Plastic, or HDPE. The concrete will crack, and the bamboo will find a way out. Many people make ill-advised attempts at using metal, wood, or concrete to slow down the underground roots all of these decompose over time. When you want to keep your bamboo without performing yearly root maintenance, installation of a rhizome root barrier is an excellent option.
