Homeowners may appreciate trees for their aesthetic value, cooling shade, and ecological benefits, but they may be unaware of the danger they bring to their property when they grow too close to the house. In this manual, we’ll look at the ways in which trees can compromise your house’s stability, including those that you might not have even considered. To help you keep your home safe without sacrificing the aesthetic value of your yard, we’ll go over everything from the complicated root systems below ground to the subtle symptoms of foundation problems. The first step towards a secure and amicable relationship between your house and the trees around it is to have an appreciation for the ways in which trees can pose a threat to its foundation.
Can Tree Roots Really Ruin Your Home’s Foundation?
Growing tree roots can undermine a building’s foundation by either physically impacting the structure or altering the soil conditions nearby and beneath it. Roots spread out in a horizontal pattern just below the surface of the soil. Roots begin to grow downward when they come into contact with impermeable materials, including pipelines, sidewalks, kerbs, and foundations.
But if there’s a hole nearby (like from a burst pipe), the tree’s roots will squeeze through it to get to the water and nutrients they need. They can also displace the earth around them, which can lead to foundation movement and severe stress.
How Do Tree Roots Cause Damage To Buildings?
Trees’ thirst can erode the support of buildings. Roots of any size can develop aggressive tendencies if they are constantly battling for scarce resources like water and food. Check out some real-world examples of the harm that tree roots can cause to a house’s base.
Soil Shifting
The foundation begins to settle because its stability is dependent on the surrounding soil; as the roots expand and the soil dries up, the foundation becomes unsupported.
Weather Changes
Damage to a building’s foundation can also be caused by bad weather. Roots can contract when the clay soil dries out in dry spells and grow when the earth is saturated with water after a downpour. These shifts can weaken the ground by causing fissures beneath the surface.
Concrete Buckling
Changes in the ground can cause cracks in walls and ceilings and even cause beams to move. Settling concrete is not necessarily dangerous, but it might weaken the foundation of an older house.
Plumbing Damage
If your home’s sewer system has any leakage, the roots may try to find water elsewhere, which could cause expensive damage. Roots can invade your plumbing system through the tiniest of openings, seeking to gain access to the water and nutrients that pass through it.
Warnings That Tree Roots Are Weakening Your House’s Structure
There are certain warning indicators that tree roots may be a problem near your home’s structure. Some warning signs are listed below.
Cracks In The Walls Around A Tree
You’ll see fissures in your foundation’s walls and floor, especially on the sunniest side. The roots of the wrong tree can wreak havoc on your home’s foundation, patio, and even asphalt. Find out how the trees and bushes on your property affect the landscape and the buildings on it by identifying them all.
Houses can lean towards trees because their roots pull water from the ground, which then causes the foundation to move or even collapse.
Cracks Appearing in the Concrete
Roots can find their way through cracks in concrete or pavers, causing uneven surfaces that can be hazardous for walking.
Plumbing Issues
Signs of a broken plumbing system include low water pressure or clogged drains that won’t clear with a plunger or other similar tools.
Can Tree Removal Harm a House’s Foundation?
When tree roots threaten to undermine your home’s structure, removal of the offending tree is generally the only option. However, you may be concerned that cutting down the tree could present its own set of issues. Even if cutting down the tree is usually the best option, there are always some complications that could arise.
Risk Of Soil Erosion
When dwellings are constructed on or near sloped ground, cutting down a tree can hasten soil erosion. In the absence of a tree’s roots, the soil on a slope is more likely to erode.
Potential for Water Damage and Foundation Cracks
When a tree is cut down, the earth is able to keep the water that was being sent to the roots. This is desirable because it allows soil to regain some of its lost height. However, this can also lead to more pooling water, which can seep into your home through the fractures in the foundation that the trees’ roots have already created.
How To Protect A Foundation From Tree Roots?
Install Root Barriers
Putting in a root barrier can help stop any more destruction. This is essential prior to any tree planting. To prevent tree roots from damaging your home’s foundation, gas lines, or water pipes, install a root barrier.
Root barriers can be either chemical or mechanical. By suffocating the roots, chemical root barriers prevent them from penetrating the treatment zone. Roots can be diverted away from your home’s foundation and plumbing by installing a mechanical barrier made of concrete, metal, or plastic.
It is recommended to hire a specialist to install a root barrier. They know where the gas and water lines are, and they know how to properly place the barrier. A root barrier won’t do its job if it’s installed incorrectly.
Maintain Home’s Foundation
If the roots of your trees can’t find any openings in the foundation to expand into, they won’t be able to do any damage. The best way to keep your house safe is to take precautions. The roots of a tree can exacerbate existing cracks in the pavement, making the situation worse. Small fractures in the foundation should be fixed before they spread and cause serious structural problems. Preventing root damage to your home’s foundation is as simple as keeping it well-maintained.
Plan Location Based On The Root System
The growth pattern of a root system is species-specific. Consider the tree’s root system and whether or not it will grow in the area you have in mind before making a final decision. Some tree species have downward-growing roots, whereas others have laterally-growing ones.
You should put some thought into which tree you plant and where it will go. Trees with deep, downward-growing root systems are less likely to threaten neighbouring buildings and infrastructure. Sidewalks, driveways, gas lines, and sewers can all be damaged by a tree’s roots, especially if the roots are shallow and spread out laterally.
Select Trees With Less Aggressive Roots
The root systems of some tree species are notorious for their aggressiveness. These invasive roots typically have a large, rapidly expanding root system. They also have long, straight roots that grow close to the ground’s surface. The roots of some plants can reach a width of 40 metres or more. Avoid planting trees near your home or business if you’re worried about their invasive root systems.
Choose trees with shallower, less disruptive roots. Smaller, more controllable root systems make these trees a good option for tighter spaces or those located close to utilities and foundations. Plants used for landscaping provide shade, and some types of fruit trees have shallower roots than others.
Control Water Sources
In search of moisture and food, roots spread outward. The root system will expand towards any leaks in pipes if the water source is not managed properly. For water and sewage lines, this is a major issue. Roots will seek out water pipelines to potentially damage them if the source is not addressed.
If the issue persists, you may need to take more drastic measures, such as using a chemical root barrier or cutting off the section of the root that is obstructing the pipes. If you want the root removed without destroying the tree, hire a professional arborist. The pipe should then be fixed to stop the leak.
Remove Dangerous Trees
If a tree’s roots are wreaking havoc on your foundation, it may be in your best interest to have the tree removed. This will stop any additional erosion and give you the opportunity to resurface and level the base. A qualified arborist should be hired if tree removal is necessary. Tree cutting is a risky business that calls for specialised gear. If you don’t take precautions, you could endanger yourself, your family, and your home.
Trees That Shouldn’t Be Planted Near Your Foundation
A house should never be built near certain trees. They may eventually become too tall, and their branches may encroach on your land. They also have aggressive root systems that can damage your house’s foundation. Listed below are species of trees best left out of your yard:
- Oak trees
- Silver maple
- Norway maple
- White ash
- Aspen
- American elm
- Cottonwood
- Weeping willow
- Poplar
If any of these trees are in close proximity to your home, you should hire a tree service to cut them down and haul them away.
Tree Removal Is The Last Resort
Don’t go chopping down your big old trees just because you’ve gotten this far into the article. Cutting down trees isn’t the answer to everything. If you properly maintain your trees, you can have lovely trees in your garden without worrying about soil sinking and foundation damage.
- Oaks and sugar maples are examples of slow-growing species with less invasive root systems that are good options when planting new trees in a yard. Keep your distance from trees like willows, silver maples, and elms because their roots can be sneaky. Before planting a tree, it’s a good idea to get professional guidance from an arborist like Martin’s Tree Services if you have any questions regarding the expected size of the tree or its root system.
- Watering trees close to your house prevents the roots from drying out or swelling unnaturally.
- A root barrier can be constructed between your property and any nearby huge trees. Cutting back the roots that are getting too close to your house’s structure can keep you from having to have the tree uprooted entirely. This is not a quick remedy, but the investment in your property’s safety could be well worth it in the end.
- If you’re planning on expanding your current home or building a new one and don’t want to cut down any of the large, mature trees on your land, you’ll need to dig deep enough for your foundations. When roots shift the soil around a building, it can cause serious problems for a structure with a shallow foundation.
Conclusion
Trees, while providing aesthetic and ecological benefits, can also pose a threat to a house’s foundation. Growing tree roots can physically impact the structure or alter soil conditions near and beneath it. Roots spread horizontally just below the surface of the soil and begin to grow downward when they come into contact with impermeable materials, such as pipelines, sidewalks, kerbs, and foundations. If there is a hole nearby, the tree’s roots squeeze through it to get water and nutrients, and displace the earth around them, leading to foundation movement and severe stress.
Tree roots can cause damage to buildings by causing soil shifting, weather changes, concrete buckling, and plumbing damage. Warning signs include cracks in the walls around a tree, uneven surfaces in concrete or pavers, and broken plumbing issues.
Removing a tree can be the only option when tree roots threaten to undermine a house’s structure. However, cutting down a tree can also present complications, such as soil erosion and potential water damage and foundation cracks. To protect a foundation from tree roots, installing root barriers is essential before tree planting. These barriers can be either chemical or mechanical, and it is recommended to hire a specialist to install them correctly. By understanding the dangers of trees and their potential impact on a home’s stability, homeowners can maintain a secure and amicable relationship with their surrounding trees.
To prevent tree damage to your home’s foundation, take precautions and consider the root system of the tree. Trees with deep, downward-growing roots are less likely to threaten neighboring buildings and infrastructure, while trees with shallower, less disruptive roots are suitable for tighter spaces or those close to utilities and foundations.
Control water sources by using a chemical root barrier or cutting off the root section that is obstructing the pipes. If the root is causing erosion, hire a professional arborist to remove it without destroying the tree. If the tree’s roots are wreaking havoc on your foundation, have it removed to stop erosion and level the base. Trees that should not be planted near your foundation include oak trees, silver maple, Norway maple, white ash, Aspen, American elm, cottonwood, weeping willow, and poplar. Hire a tree service to cut them down and haul them away if they are in close proximity to your home.
Tree removal is not the answer to everything; proper maintenance can prevent soil sinking and foundation damage. Water trees close to your house to prevent roots from drying out or swelling unnaturally. A root barrier can be constructed between your property and nearby large trees to prevent tree uprooting. If you plan to expand your current home or build a new one without cutting down large mature trees, dig deep enough for your foundations to prevent root damage.
