Root Barrier For Bamboo- How to Stop Bamboo From Sperading

Posted by Team SolaWrap and the Green Thumbs. on Fri, Apr 21, 2023 @ 10:24

Bamboo Root Barrier- It Works!

High-Density Polyethylene (HDPE) is a highly durable and impermeable synthetic material that can be used as a root barrier to prevent bamboo roots from spreading uncontrollably. When installed correctly, an HDPE liner can create an impenetrable barrier that prevents bamboo roots from growing beyond a designated area.

How Does HDPE Work as a Root Barrier?

  1. HDPE liners are usually placed at a depth of at least 24 inches (60 cm) below the soil surface. This depth is sufficient to prevent most bamboo species from penetrating the barrier.

  2. The HDPE liner is made up of large, solid sheets or panels that are carefully laid out and joined together to create a continuous barrier. This barrier prevents the bamboo roots from spreading beyond the designated area.

  3. Because HDPE is impermeable, it also prevents water and nutrients from passing through the barrier. This can be an advantage in preventing the bamboo from spreading, but it may require supplemental watering and fertilization within the designated area.

  4. The edges of the HDPE liner are usually turned up at the edges to prevent roots from growing under the barrier. Additionally, it is important to ensure that the liner is properly secured at the edges and that there are no gaps in the barrier that the roots could exploit.

  5. In order for the HDPE liner to be effective, it must be properly installed by professionals who have experience with root barriers. Proper installation will ensure that the barrier is continuous and secure, preventing the bamboo roots from penetrating or circumventing the barrier.

Overall, an HDPE liner can be an effective root barrier for controlling bamboo growth. However, it is important to note that no root barrier is foolproof, and regular monitoring and maintenance will be required to ensure that the barrier remains intact and effective over time.

Plastic Sheeting 101

Plastic & Plastic Sheeting 101 

Plastic is the common name for a wide range of synthetic materials made from petrochemicals.  Plastic has had a big role in building materials due to some of its properties. Here are a fraction of the advantages:
  • Parts made from plastic are strong yet lightweight. They are easy to maneuver and put to use.
  • Hard plastic has excellent weather ability. It is durable, knock-and-scratch resistant.  Flexible plastic sheeting on the other hand does not weather well at all unless it has a U.V. additive added to the formulation to allow it to withstand the U.V. from the sun and atmosphere.
  • Hard plastic such as HDPE does not rot or corrode.
  • Plastic is remarkable in the fact that it has limitless possibilities in design achived by extrusion, bending and molding.  When plastic is made into its flexible form, plastic sheeting has countless applications it assists.
  • Plastic both hard and in the flexible form can be sewn and nailed.
  • Plastic can be recycled.
  • It is a poor conductor of electricity.

Products Made Of Plastic in the Construction Industry:

  • Insulation materials: PVC sheets, insulating membranes.
  • Pipes  : Electrical Conduits, Rain Water & Sewage pipes, Plumbing, Gas Distributions.
  • Cables : PVC Insulation on cables, Insulation Tapes .
  • Flooring : Flooring tiles & Rolls .
  • Domes / sky lights : Opaque as well as transparent.
  • Roofing  : colored or Double skinned for insulation.
  • Windows & doors : Extruded sections for Door and windows and panels.
In its simplest terms, the main difference between the different types of plastic is the way their cellular structure, or mol ecules bond with each other, and how tightly they are formed.

1) Low Density Polyethylene (LDPE), most common type of plastic sheeting, very flexible, most often from 0.5 mil thick to about 40 mil in flexible sheeting forms. Good conformability to surfaces. Because the cell structure is not as strong or dense as some other types of plastic sheeting, it is not typically as strong or puncture resistant as other forms or blends, but has thousands of common uses. Widely used for everything from construction and agricultural sheeting (often called Visqueen), Engineered Plastic Sheeting of countless types for such things as Vapor Retarders (also called Vapor Barriers by many), Surface Protection films, Pond and Canal Liners, Covers, Tarps, Abatement Plastic, Containment, packaging, and the list goes on.

2) Linear Low Density Polyethylene (LLDPE), blended form of LDPE where the film has much more flexibility, tensile strength, and more conformability. LLDPE is "softer" and more pliable, so is an excellent choice for such things as pond liners, or blended into other films to give them extra strength and flexibility. This is perfect for an application like a self-adhesive carpet protection film, where the film needs to have an amazing amount of strength in a very thin film to absorb impacts, but not tear or puncture. In this form of poly, the molecules all line up and strongly hold together as the film is stretched to give the structure much more strength and elongation than LDPE. Most common in thicknesses ranging from 0.5 mil to 40 mil in flexible plastic sheeting.

3) Medium Density Polyethylene (MDPE), the least commonly used form of polyethylene for flexible plastic sheeting. Has more strength than LDPE, a little more chemical resistance, tighter cell structure, more puncture and tear resistance. Often blended with LDPE and or LLDPE to give the attributes one is looking for in a particular type of film. For instance, many pond liners have MDPE to add some strength and toughness, without adding too much stiffness.

4) High Density Polyethylene (HDPE, aka HD), widely used for many applications. HDPE is the strongest, toughest, most chemical resistant, and least flexible of these four types of polyethylene. It also has the most UV resistance of the bunch without additive packages to increase this attribute. HDPE has a very tight cell structure, making it very difficult for other molecules to pass through its structure on a microscopic level. HDPE is the most easily field seamed of these products, and is generally used on an industrial level in thicknesses from about 12 mil to 100 mil thick. Most golf course ponds are lined with HDPE, most industrial ponds and canal liners, secondary containment liners, root barriers, many applications where chemical resistance is needed. This is also used in thousands or maybe millions of applications in thinner forms, especially in blends with the other types of polyethylene, because the HDPE adds much strength and toughness with its very tight bonds with other molecules.

The density of polyethylene is measured in a column of water, and they are all classified depending on ranges of density. LDPE (and LLDPE) are generally within the range of 0.919-0.924 g/cm³. MDPE are generally within the range of 0.926-0.940 g/cm³. HDPE are generally within the range of 0.941-0.965 g/cm³. These numbers can vary slightly depending on your source, and are not set in stone, just general guidelines.
