Tree Roots Are Buckling My Concrete Driveway

Tree roots constantly seek a water source, in doing so, they can spread very deep or very shallow and in a very large radius from the trunk. When roots spread at shallow depths, they will find their way under asphalt, sidewalks, and yes, driveways.

As the roots naturally expand and thicken, they will displace everything around them creating tremendous potential energy. This energy is usually released upward (path of least resistance), resulting in the breaking, cracking, warping, or buckling of whatever structure is above.

Here, we will discuss measures you can take to repair damaged concrete, remove damaging roots, and how to avoid this issue in the future.

How Much of the Tree’s Roots Can Be Removed

The answer to this isn’t quite as simple as it may seem. Here are some factors to consider:

Tree Roots Three Inches or More in Diameter – When cutting roots this size, they typically will not grow back. However, a wound this large leaves the root susceptible to insect and disease. Often times, this allows rot to reach all the way back to the trunk, seriously compromising the health of the tree.

Tree Roots Less Than Two Inches in Diameter – Tree roots this size are typically able to regenerate. Removing them will only e a temporary fix.

Tree Roots Grow Far and Wide – Typically, you will find that one inch converts to about a foot and a half. That is, for every inch at DBH (Diameter at Breast Height – measured 4.5 feet above the ground), the roots will extend up to a foot and a half away from the tree trunk. A twelve inch trunk at DBH means roots are extending up to eighteen feet away from the trunk in every direction.

Tree Roots Are Sensitive to Disturbance – Tree roots seek out uncompacted soil rich in oxygen (like the soil under sidewalks and driveways). When the soil underneath a tree is compacted by heavy machinery or used as a storage area for a construction site, the roots beneath the surface are literally being choked to death. Eventually, this will result in the decline of the tree’s health, leading to its death.

Tree Roots Under the Driveway – Roots provide structural integrity to a tree. If they have grown under the driveway, the driveway is now a part of its structural integrity. Depending on the size and depth of the roots, removing them may lead to the falling of the tree in severe weather.

More often than not, by the time tree roots have buckled your driveway, you may be faced with the ultimate removal of the tree, if you are to break up and re-lay the affected portion of the driveway.

How to Repair Your Driveway and Save Tree Roots

If the tree is a keeper in your landscape and the roots in question are vital to its survival, there are construction options or methods which will allow the coexistence of the roots and your driveway. Here is one of the multiple options you may use:

Aggregate Surfacing – This technique requires the cutting and careful removal of the damaged concrete. Once the concrete has been removed, the surface below is covered with driveway fabric (aka: geotextile fabric), then four to five inches of dense grade aggregate (DGA) or road stone. The project is completed by using edging along the sides to prevent the aggregate from spreading laterally.

Tree Species, Watering, and Location Matter

Ultimately, it is the lack of planning or the proper information to form a plan that lead to situations such as these. Before planting a tree, you should be aware of its species, potential growth, root spread capacity, and if its roots are typically classified as invasive or not.

Location is a key factor in the survival of any tree or plant. Planting a tree too close to a structure is like inviting a bull into a china cabinet. As trees grow, they instinctively seek out water sources, expand their canopies, and potentially wreak havoc on the structure they were planted next to.

Once a tree is planted, frequent watering will help its root system to grow deeper. Shallow root systems often reflect insufficient watering or compacted soil further beneath the surface.

Professional Tree and Tree Root Removal

While the solution you choose may be an easy one, innocent mistakes may lead to a much more serious situation as your tree’s health declines and ultimately dies.

Before any steps are taken to remove a tree or a portion of its root system, it is highly recommended to seek the advice of a certified arborist. An arborist is a tree professional trained to spot trouble pertaining to tree issues and how to efficiently resolve them.

Signs of a Diseased Tree – Dieback, Tree Suckers & Water Sprouts

Spruce with dieback needs tree care to preserve healthy landscape.

Many diverse diseases affect your landscape, shrubs and trees. Identifying these diseases is critical because, not all tree diseases can be controlled. We love to watch things grow when we garden but we must note that not all growth is positive or advantageous to the trees. Some of these growths take energy away from the tree; common examples include water sprouts and suckers. At 72tree.com we often see the damaging effects of tree disease, and in this article, dieback, tree suckers and water sprouts are the disorders we’ll be discussing.

Dieback of a Tree or Its Limbs

In spring as the weather gets warmer, and buds start noticeably leafing out, you might notice that a section or even an entire limb is not leafing out consistent with the rest of the tree. Dieback is a condition in which the ends of the tree branches die. These sections are generally located at the limb tips, but can also be entire limbs or sections of the tree where there will be no leaves. Most times, this is a sign that all is not right with the tree.

Water Sprouts Due to Branch Removal

Water sprouts are dynamic shoots that develop from dormant buds either on large branches or trunks of a tree. They are usually upright and in many cases occur as a result of the removal or trimming of large branches. Heavy pruning may also lead to the production of more sprouts. Tree stress may also result in water sprout growth, but it’s not usually as vibrant as those that occur due to pruning.

Trees should be checked regularly. If you notice new shoots, eliminate them by rubbing them off as they emerge. Large water sprouts can be pruned off close to the trees trunk. Water sprouts can ruin a tree’s shape and they also divert the tree’s energy by blocking air circulation and light. Though not advised, some allow sprouts to grow in the place of missing branches, but it may lead to a reduction in quality of the tree’s ability to bear more fruits. Also, water sprouts are more inclined to promote tears, disease and breaks, as they are generally weaker than other branches.

Tree Suckers

Suckers are un-planned, vegetative growths that stem from a tree’s root system. Suckers grow from rootstock and divert nutrients away from the trees top growth. There isn’t any actual benefit from letting suckers grow because, rootstocks are usually different from the type of tree that you planted (example - a Gala apple tree will not have a Gala apple rootstock).

To find and cut from the base of a sucker, you may have to pull back any ground cover and dig up some soil to fully expose the sucker. Ensure that as much growth as possible is removed to reduce the potential of them popping up again. If they do re-emerge, this simple process will have to be repeated. Although suckers and water sprouts are similar, remember suckers originate from the root or base of the tree.

Tree Disease Prevention and Care

You might be able to deal with a disease that occurs on your trees and shrubs but you ought to consider consulting a local arborist or tree service professional if you are uncertain. The arborist will identify any disease and offer you the best treatment options and the ideal time to care for the tree.

Early spring (during most maintenance pruning) is the best time to remove both water sprouts and tree suckers. However, these unwanted growths sometimes sprout and occur during the growing season, they should be removed as soon as you notice their existence. Your trees will thank you and be fruitful!
