🌳 Installing Root Barriers to Protect Trees and Structures 🌳

Introduction:

Trees are a valuable asset in any landscape, providing shade, beauty, and environmental benefits. However, sometimes the roots of trees can cause problems by lifting pavements, damaging foundations, or infiltrating underground structures. In such cases, the installation of root barriers becomes necessary to mitigate these issues and ensure the health of both the tree and the surrounding structures. In this article, we will explore the process of installing root barriers, how they work, and their importance in preventing root-related damage.

Background of the Tree:

The tree in question is a western red cedar that has been growing for approximately 30 years. Despite being cut down to a stump at one point, it managed to regenerate and now displays an unusual growth pattern. It is shorter and wider than typical for its species. Unfortunately, this growth has led to the roots infiltrating the customer's patio, causing concerns about potential damage to the foundation over time.

The Problem with the Roots:

The presence of the tree's roots beneath the paver patio has resulted in lifting and damage. The customer is worried about the roots reaching the foundation and causing long-term structural issues. To address this problem, the installation of a root barrier is necessary to redirect the growth of future roots away from the foundations of the house.

The Solution: Root Barrier Installation:

A root barrier is a physical barrier made of interlocking plastic pieces designed to prevent roots from growing in a specific direction. By installing a root barrier, the tree's roots will be redirected outward when they come into contact with the plastic barrier, ensuring they do not continue growing towards the house's foundation or other structures.

How Root Barriers Work:

When roots encounter the plastic barrier, they naturally follow the path of least resistance and redirect their growth away from the barrier. The barrier essentially serves as a guide for the roots, preventing them from infiltrating the surrounding area. This way, the foundation, patio, or pavement remains protected from root-related damage.

Overcoming Obstacles during Installation:

During the installation of root barriers, it is common to encounter obstacles that cannot be moved, such as water lines or drain pipes. In such cases, the barriers may need to be notched to accommodate these immovable obstacles. This ensures a continuous barrier without compromising its effectiveness.

Assessing and Pruning the Roots:

Before installing the root barrier, it is essential to assess the roots' condition and determine if pruning is required. Pruning involves removing any roots that may pose a risk to the tree's stability and health. The goal is to strike a balance between maintaining the tree's well-being and preventing further damage to the structures.

Installing the Barrier:

The root barrier consists of two-foot-long interlocking pieces that are inserted into a prepared trench. Once the barrier is in place, the trench is filled back with soil, ensuring the roots are adequately watered and compacted, providing a stable foundation for the patio or pavement above. Additionally, a layer of sand is added to create a base for the pavers.

Finishing the Project:

Once the installation is complete, the pavers are carefully placed and aligned, giving the patio or pavement a clean and polished look. The newly installed root barrier ensures that future root growth will be directed away from the protected area, minimizing the risk of damage to the surrounding structures.

The Best Material for Root Barriers:

Deep Root, a company based in San Francisco, manufactures a high-quality root barrier material that is widely regarded as one of the best options available. Their product is made of durable and interlocking plastic pieces that effectively redirect the growth of tree roots. Deep Root also offers other innovative products, such as Silva Cells, which provide structural support for pavements while allowing soil space for the healthy growth of tree roots.

The Risk and Mitigation of Root Pruning:

Root pruning carries the risk of removing too many or essential root systems, which can detrimentally impact the tree's stability. However, in the case of this particular tree with prior over pruning, the risk is somewhat mitigated. The shortened lever arm created by the previous pruning reduces movement in the root system, subsequently reducing the risk of damage caused by root movement during strong winds.

The Importance of Root Barriers for New Pavements:

If you are planning to install new pavements in an area with existing trees, it is essential to consider the installation of root barriers. This proactive approach not only protects the integrity of the pavements but also ensures the longevity and well-being of the surrounding trees. Consulting with experts, such as Root Cause, can provide valuable insights and guidance during the installation process.

Conclusion:

Root barriers offer an effective way to prevent root-related damage to structures while simultaneously protecting the health of trees. By redirecting root growth away from foundations, patios, and pavements, these barriers provide a practical and long-lasting solution. With proper installation and pruning techniques, property owners can enjoy the benefits of beautiful trees without compromising the integrity of surrounding structures.

FAQ:

Q: Can I install a root barrier myself? A: While it is possible for some individuals to install a root barrier themselves, it is recommended to consult with professionals who have experience in root barrier installation. They can ensure proper assessment, pruning, and installation techniques.

Q: How long does a root barrier last? A: When installed correctly, root barriers can last for many years. Their durability depends on various factors, such as the quality of the materials used and the surrounding soil conditions.

Q: Will a root barrier harm the tree? A: No, a properly installed root barrier will not harm the tree. In fact, it protects both the tree and the surrounding structures by redirecting root growth away from foundations and pavements.

Q: Can I install a root barrier after my pavement is already damaged? A: While it is possible to install a root barrier after pavement damage has occurred, it is more effective and cost-efficient to install it preventively during the initial pavement installation or renovation.
