Tree roots, a silent force of nature, often go unnoticed until they cause foundation problems. This issue plagues homeowners, so let’s explore how to tackle this threat before it undermines your entire house.
Understanding the Root of the Problem
Trees need water. Their roots constantly seek it out, often leading them toward the moisture surrounding your foundation.
The extent of tree root damage foundation boils down to a few crucial factors—the tree type, the soil type, and your home’s foundation.
Some tree species, like willow trees, silver maples, and American elms, have aggressive root systems that grow rapidly and spread wide, causing damage.
Soil Type Plays a Role
Clay soils tend to compact as roots grow, causing foundation settlement. In looser soils, roots can displace the earth, creating voids beneath your home.
This shifting soil leads to foundation cracks. It’s like pulling the rug out from under your house—much slower, but just as detrimental.
Compacted soil beneath a home can also contribute to foundation issues.
Recognizing the Signs of Tree Roots Foundation Damage
How can you tell if tree roots are damaging your foundation? Some signs aren’t immediately visible. Sticking doors and windows are one example.
Cracks in walls (especially horizontal or stair-step cracks in brick) are another red flag. Uneven or cracked floors are signs too.
Gaps between walls and ceilings or floors can indicate foundation damage. Your chimney or porch might begin separating from your house. Look for changes in vertical cracks, which can signal foundation plant damage.
Look for Changes Inside and Outside Your House
A thorough examination inside and out is important, especially near root systems. Check areas with roots growing near the foundation.
Roots damaging your foundation should be addressed as soon as possible to avoid higher repair costs. Consider soil beneath the foundation, a crucial aspect of preventing foundation cracks.
How to Protect your Home from Invasive Tree Roots
How can you stop tree root foundation damage? Implement a root barrier.
These plastic or metal sheets redirect roots downwards, away from your foundation.
Sometimes, improper planting trees is the problem. A root barrier installed around the stump pushes roots down, preventing them from damaging foundations.
| Method | Description | Pros | Cons |
|---|---|---|---|
| Root Barriers | Physical barriers installed in the ground to redirect root growth. | Effective at preventing root intrusion, relatively low cost. | May require professional installation, not effective against existing roots. |
| Chemical Treatment | Applying chemicals to kill roots near the foundation. | Can be effective at killing existing roots. | May harm the tree, can be hazardous to the environment. |
| Tree Removal | Removing the offending tree entirely. | Permanent solution to root intrusion. | Can be expensive, may be undesirable if you want to preserve trees. |
| Root Pruning | Cutting back roots that are close to the foundation. | Less invasive than tree removal. | May not be a permanent solution, requires careful execution to avoid harming the tree. |
Foundation Repair Solutions for Tree Root Damage
What to do once damage has occurred depends on the situation. Solutions might involve underpinning with piers or anchors, filling voids, or re-grading around the house. It’s best to consult with a foundation repair company.
Consider avoiding planting trees with invasive roots near your home, especially hybrid poplars and poplar trees. Roots can’t penetrate a solid barrier. Planting trees strategically is key to foundation maintenance.
Prevent problems by avoiding planting trees close to your foundation. Newer homes are especially vulnerable to foundation issues.
Conclusion
Tree root foundation damage can be addressed by homeowners willing to learn about their property, including the trees, soil, and existing damage signs.
While trees enhance your property, take preventative steps. Avoid planting trees with aggressive roots, like willow trees, near your home. This is much easier (and cheaper) than repairing costly tree root foundation damage later.
