Plastic barriers are often installed around trees to prevent invasive root growth and protect infrastructure, garden beds, and landscaping. These barriers are typically made of high-density polyethylene (HDPE) plastic, which is durable, flexible, and resistant to environmental conditions and chemicals. Root barriers are designed to redirect tree roots, preventing them from invading landscapes and causing structural damage. They also help manage excessive moisture, protecting trees from invasive roots. The installation process involves unrolling the HDPE plastic vertically with the smooth side facing the tree and securing it to the ground with staples or anchors. The thickness of the barrier is crucial for its effectiveness, with recommended thicknesses ranging from 40 to 80 mils.

Plastic tree root barriers prevent structural damage
Plastic tree root barriers are an effective way to prevent structural damage caused by intrusive tree roots. Tree roots can cause a lot of problems for homeowners and gardeners. These aggressive roots can get into foundations, garden beds, sidewalks, and sewer lines, leading to costly repairs.
Roots of trees and shrubs can cause significant damage to gardens, public spaces, and roads. They can also cause invisible damage, such as plumbing problems, by blocking and breaking sewer lines and water pipes. Therefore, it is essential to control and manage their growth.
Tree root barriers are perfect for protecting your landscaping from invasive roots. These barriers are made of heavy-duty plastic sheeting that will stop roots from growing through the foundation. They are easy to install and can be placed up to 48 inches below grade. The simplest type of barrier is a pre-manufactured one, typically made of high-density polyethylene (HDPE) or polypropylene, ranging from 40 to 80 mils thick. This thickness provides a sturdy and impenetrable barrier that also helps prevent excessive moisture from reaching the tree's roots.
HDPE plastic barriers are durable and can control invasive tree roots for an extended period. They are chemically resistant and will not degrade when exposed to fertilizers or soil. The flexibility of HDPE allows it to fit around structures and be customized for installation without disturbing the current landscape. Additionally, it is environmentally safe, as it is a non-toxic material that will not leak harmful chemicals into the soil.

They redirect roots and protect buildings and foundations
Tree root barriers are designed to protect buildings and their foundations from damage caused by invasive tree roots. Roots can break through concrete, damage plumbing, and cause structural damage to buildings. Root barriers redirect roots, guiding them to grow in the direction they are meant to, and preventing them from reaching and damaging nearby structures.
Roots are naturally driven towards sources of moisture and nutrients, which can lead them towards foundations, plumbing, and landscaping. Tree roots can cause plumbing problems as they seek out water, blocking and eventually breaking sewer lines and water pipes. They can also break through sidewalks, foundations, and driveways, causing expensive damage and requiring costly repairs.
Root barriers are made of heavy-duty plastic sheeting that prevents roots from growing through it. They are impenetrable to roots but allow water to pass through. The thickness of the barrier is important for its effectiveness, with thicker barriers providing better protection. The material is also flexible, allowing it to be installed in a number of vertical or horizontal applications and customized to fit around structures and landscaping features.
High-density polyethylene (HDPE) plastic is commonly used for root barriers. It is durable, flexible, and resistant to environmental conditions and chemicals found in fertilizers and soil. It is also environmentally safe, as it is non-toxic and will not leak harmful chemicals into the soil. Root barriers made from HDPE plastic can be an effective and long-lasting solution to protect buildings and foundations from invasive tree roots.

Root barriers are made from heavy-duty plastic sheeting
Root barriers are an effective way to manage the growth of tree roots and prevent damage to infrastructure, plumbing, and landscaping. They are especially useful when installed with new tree plantings, as they guide the roots to grow in the intended direction.
These barriers are made of heavy-duty plastic sheeting, typically High-Density Polyethylene (HDPE), a durable and flexible material. The thickness of HDPE barriers ranges from 40 to 100 mils, with some barriers thicker than two stacked credit cards. This thickness provides a sturdy and dependable barrier that can deflect most tree and bamboo roots.
The flexibility of HDPE plastic allows for easy installation in vertical or horizontal applications. It can be customized to fit around structures and landscaping features, effectively blocking root growth. The plastic is also resistant to chemicals, including those found in fertilizers and soil, ensuring that the barriers do not degrade over time.
To install a root barrier, a trench is dug around the tree, and the HDPE plastic is unrolled and positioned vertically, with the smooth side facing the tree. The plastic is secured to the ground using heavy-duty staples or anchors, ensuring no gaps are present. The trench is then backfilled with gravel or soil to provide stability.
Root barriers made from heavy-duty plastic sheeting offer a long-lasting and environmentally safe solution to manage invasive tree roots and protect infrastructure, plumbing, and landscaping from damage.

They can be installed up to 48 inches below grade
Tree root barriers are used to prevent damage to infrastructure, plumbing, and landscaping. They are made of heavy-duty plastic sheeting that stops roots from growing through foundations, sidewalks, driveways, sewer lines, and garden beds. These barriers are especially useful when installed at the time of planting a new tree, as they guide the roots to grow in the desired direction.
The plastic barriers are made of High-Density Polyethylene (HDPE) and are available in varying thicknesses, from 40 to 100 mils. The thicker the barrier, the more resistant it is to root penetration. The height of the barrier also matters, as it should be tall enough to block most root growth. While the average height ranges from 12 to 48 inches, certain trees with deeper root systems may require taller barriers.
HDPE barriers are flexible and can be installed up to 48 inches below grade, making them suitable for a variety of vertical or horizontal applications. They are also durable, chemical-resistant, and environmentally safe. The seamless installation of HDPE barriers ensures that there are no weak points for roots to penetrate, making them an effective solution for root management.
In addition to plastic barriers, fabric barriers with embedded chemicals are also available. These fabrics release chemicals into the surrounding soil, preventing root growth for about 15 years. An example of this is the BIOBARRIER Root Control Fabric, which was installed in a facility in Quebec, effectively eliminating vegetation and reducing maintenance costs.
