Our root barrier for mature trees is able to withstand even the most demanding root intrusion issues. Constructed of HDPE the material provides a minimum thickness of 80 mil. Additionally the material is available in roll widths ranging from 18” to 48”. The material is placed vertically in the ground with one inch visible above the surface. The reason for this is so that surface roots can be quickly identified and clipped back.

The root barrier is shipped in long rolls which allows for a continuous barrier with minimal joints which, especially when dealing with mature trees is ideal as the joints are always the weakest point of any root barrier.

The root barrier is manufactured in the USA from recycled materials.

 

Note: Our HDPE plastic is only available in roll widths up to 96 inches (8 feet).

Please note that we are unable to provide custom roll lengths.

Connecting HDPE Pieces

There are two ways to connect multiple pieces of HDPE together. One method is to overlap the HDPE and use our double sided seam tape to connect the two pieces. The other method is to butt the ends together and use our 17 mil single sided seam tape to create a solid connection.

Overlap Method
(for underground installations)

The overlap method is best used when connecting two pieces of HDPE in a buried application. Due to the overlap, a ridge is exposed which is not ideal when installed in exposed vertical or flat installations in high traffic areas as there is a possibility of an object catching on the ridge and pulling the two pieces apart.

In a below ground installation, the large overlap area provides a more water resistant connection as well as enhanced protection against tree and plant root intrusion.

End to End Method (for exposed installations)

When installing HDPE on a wall, floor or anywhere that is exposed, the end to end method provides a secure connection and does not leave any ridges exposed to potential catching by a person or object.

    Protecting Your Garden From Tree Roots

    If you believe your garden is being invaded by tree roots, you have to find the source in order to address the problem. You will have to dig into the bed that is close to the nearest tree. Pull up on the root to see it and what direction it's coming from. If the root is thin, breaks easily, and looks like a vine, chances are it's coming from weeds, not trees. If the root is thick and woody then it's coming from a tree. You need to dig it up for a better look. The size of the tree will give you a good idea about the problem. Also, if the tree is large, you will have to deal with more than one root to solve the problem. In many cases, you can almost visualize the direction of the roots as they travel outwards from the tree.

    Dig An Appropriate Trench

    After realizing the extent of the roots, you can get a good idea of how long the trench will have to be. The trench should be around 18 inches wide for you to stand in while digging deeper into the soil. The depth of the trench should be deeper than the roots can travel. Make sure to have a step at one end of the trench so you can get in and out of it.

    As you run into rocks, place them on the surface above ground next to the trench. When you are ready to backfill you have to throw the rocks back in the trench. Lay down a tarp, or other cloth, on the ground going in the direction you are digging in. While digging, place the soil on the tarp it'll be easier to put the soil back when you fill the trench back in.

    Apply a Pruning Saw For Cutting The Roots

    At some point, you will come in contact with the invasive root. Using a small hand pruning saw, cut it from both sides of the trench This will clear the trench of roots. Set the roots in a pile near one side of the trench. You can look at them later to see the progress you've made.

    Install and HDPE Root Barrier

    It is important to install a root barrier with does not decompose and provides enough puncture resistance to repel the tree roots. HDPE provides an approximate 100 year lifespan when installed underground and is available in a variety of different thicknesses. 80 mil or greater is recommended for protection against tree roots. Install the HDPE in your trench with approximately 2” extending out of the ground. This will provide you with a line of sight to catch any surface roots that attempt to “jump” the barrier.

    Discard The Rocks Into The Bottom Of The Trench And Fill It

    Throw any collected rocks back in and then fill them in with dirt. You can overfill the trench as dirt compresses a few inches when it's walked on.

    Some severed roots will still be left behind in the beds but you do not have to dig them up and remove them. Over time, they will rot away and become nutrients for your landscape.

    Erecting a barrier might seem like a lot of work but once you get started, it will go fast. It's a great feeling knowing you have protected your garden beds from invasive roots. All the improvements, fertilizers, and water you have given your garden will go to the health and well-being of your plants which is ideal.
