Underground Root Control Barrier



The Underground Root Control Barrier is designed to contain the tree roots to a specific area of the landscape without harming the tree. Without a root barrier, tree roots often cause damage to driveways, walkways, hardscapes, home foundations and septic systems.

Trees send down their roots at varying depths which can vary depending on the species of tree, soil conditions and the climate in which the tree is planted.

 We offer two different styles of tree root barriers to meet your specific site requirements.

Panel Barrier - Our panel barrier is designed with integrated vertical guides. The guides help to direct tree roots downward and greatly reduce the chance of the tree experiencing stability issues due to constrained roots. As the name suggests, this type of barrier is a series of panels that are connected together with 4-way joint strips. These joint strips provide a secure connection and allow for 90 degree turns.

HDPE Sheet Barrier - This barrier style is composed of thick, 80 mil plastic with a smooth surface. This barrier is very effective at retaining tree roots of all types. The barrier is available in 80’ and 100’ rolls (depending on roll width). Because this barrier is composed of one continuous piece, installation time is reduced.

Which style should I choose to contain roots?

It really comes down to distance that you will be placing the barrier from the tree. If you are planting the barrier in a radius close to the circumference of the tree’s canopy, it’s a good idea to go with a panel style barrier for maximum tree stability. If you are installing the barrier further away in the landscape, a sheet barrier makes more sense as there are less joints and the material is more economically priced.

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.

Stop Tree Roots From Heading Toward Your Foundation Or Sewer Lines

Not only is your home an important investment, but you may have upgraded, added features, and spent time to increase its value. Your yard is speckled with gorgeous trees that are the envy of neighbors. Lately, you have become very concerned that tree roots might be growing closer and closer in the direction of your foundation or underground lines.

You've read articles and heard stories about people facing serious repair costs and destruction to their property caused by tree roots. So, what can you do to make sure you never go through an experience like this? In this article, we will go over some signs to watch out for that tree roots might be heading toward your foundation and how to deal with it as quickly as possible.

Roots Causing Damage

Your Foundation & Invading Tree Roots

If your foundation has been regularly maintained and checked for any cracks and then repaired, the chances of tree roots invading your foundation will be practically nil. Roots can find cracks in a foundation and get in by enlarging the cracks but in general, roots will rarely damage a foundation made of concrete. On the other hand, if your trees are extremely strong with large roots, it's possible the roots could leave serious damage by trying to get through the foundation.

Some signs that you have to deal with caused by roots:

• Cracks in the foundation's floor
• Vertical cracks in the foundation's walls
• Other damages or cracks in windows with no signs of other events taking place.
• The frames on the doors and windows are uneven.
• Buckling forming on the floor's surface

Keep in mind, roots rarely cause these damages but if you experience erosion or other occurrences that could disrupt the soil under your home, it's possible you could have the above signs.

You will have to research first by digging around the foundation closest to the trees to find out if the roots are extending toward the foundation and starting to grow downward. If that's the case, you may have serious foundation problems. Investigate the roots before taking other steps.

Tips To Prevent Further Issues

It's highly recommended you install a root barrier before planting trees. These barriers will deflect roots deeper into the ground and move them away from the foundation. You can cut back roots that are heading toward the foundation but show caution as there are trees that will die even if you only cut back a small number of roots. You should contact an arborist or tree service before carrying out other steps. When you install a root barrier, make sure to nourish the tree while waiting for the tree to recover. In some cases, trees grow too quickly for you to control their root growth. The tree might have to be taken down. If that's the only alternative, hire a tree removal service to come in and do it for you. Trees are large, amazing plants that add an incredible look to your home but you cannot allow them to destroy your home's foundation.

Tree Roots Can Get Under Sidewalks & Driveways

Property owners and homeowners have experienced tree roots getting under their sidewalks, driveways, patios, and other shallow concrete structures. In turn, these roots can cause some dangerous situations. Because concrete can crack and buckle, sections will stick up causing someone to trip and become injured. The last thing you need is someone bringing a lawsuit against you.

Signs To Look For Involving Sidewalks & Driveways:

• Cracks running across the sidewalk or driveway
• Signs of bumps from roots leading to cracks
• Buckling in the concrete so the slabs will not lie flush

To solve the problem, use the same steps as you did for the foundation. Install root barriers before the roots can reach the concrete. Cut the roots and stop them with a root barrier to stop further growth. Cut down the tree and remove the root system to bring back a smooth, flat surface. Get in touch with an arborist for advice. Should you cut just the roots or cut down the entire tree?

Your Plumbing Has Been Cracked By Tree Roots

When roots get into your plumbing system they are searching for water. They will leave behind hairline cracks or loosened joints as they extend their hair-like roots into the system heading to the flow of water and nutrients. You might not see any structural damage, but you will experience several issues:

Tree Roots Damaging Pavers

Sidewalk Damage from Tree Roots

Some signs include:

• Slow-flowing drains that are not remedied using flushing treatments.
• Clogged drains that are not corrected using a plunger or other treatments
• A change in water pressure

In most cases, you do not have to cut down the tree if it has grown into the system. Simply call a tree trimming service to remove the sections that have grown into the plumbing and then call a plumber to replace the pipe. With good sealing and repairs, your plumbing will not attract trees in the future.

Keep an eye out for signs and call a tree pruning expert and point out where the signs are located. You cannot resolve the problem without bringing in a professional to help, especially when there has been damage. Contact an arborist or tree trimming service to help out then call your plumbing service or a construction contractor to take care of the repairs.
