Controls growth of bamboo by limiting rhizome (root) expansion
100 mil is thethickest barrier availableon the market. This will defend against all bamboo in all climates.
Superior to metals because it will not rust and easier to install
Protective side is chrome rolled to provide a better rhizome deflection surface.
100 mil (1/10th inch or 2.5 mm) material thickness that provides 200 pound-force puncture resistance.
Bamboo Barrier is a diversion-type control method with a smooth surface on the side facing your bamboo planting. It is made from HDPE, high-density polyethylene. Superior to metals because it will not rust and is easier to install. Bamboo roots typically travel in the first 12 inches of topsoil. Barrier is sold in 24″, 30″, and 36″ depths to provide extra protection from stray growth.
The polyethylene barrier is made from post-industrial recycled regrind material when possible, in the USA. Bamboo Shield is impermeable to water as well which acts as a water barrier. Plastic thinner than 30 mil has been shown to crack when ground temperatures 24 inches deep get below -15 degrees F. This would be extremely cold and the thickness greater than 30 mil does great at handling very cold temperatures without damage. The plastic barrier has a better chance of not cracking when frozen like other materials. Even concrete will freeze and crack over the years. Driveways are poured 4 to 6 inches deep to allow heavy vehicles passage and parking. Seldom are driveways seen without cracks. Concrete was used many years ago ( Byron Agriculture Station in Byron, Georgia) as a below-ground barrier system and found to crack below the frost line allowing bamboo rhizomes to emerge through to the other side. One of the many myths of bamboo is its ability to crack solid concrete. While a clumping type bamboo may do this, given enough years, a running type bamboo just runs and does not usually apply the outward pressure of a clumping bamboo or hardwood tree.
Bamboo is not magical, but persistent and its root system will eventually find cracks in concrete and emerge through them. If the environment ( sunlight & soil ) is suitable once it emerges the bamboo will grow if not terminated. The rhizome ( root ) when growing is very soft and flexible and will always turn when it encounters something harder. Furthermore, the installation of a barrier will accelerate the growth of a bamboo screen. The growth will be denser because of the confinements and stimulate the screening effect. The Bamboo Barrier in the 60mil x 24″ width is our most popular size and we have been selling it for over 15 years without any reported problems.
