Trees are beautiful and functional, offering shade, privacy, and natural beauty to your Michigan yard. However, while you may love the look of mature trees around your home, their roots can sometimes cause problems for nearby concrete surfaces.
If you’ve been noticing cracks, raised sections, or uneven areas on your concrete driveway or patio, tree roots could be to blame. That’s why it’s important to understand the connection between tree roots and concrete so you can figure out what’s causing the damage and how to fix it.
How Can Tree Roots Affect Concrete?
Because tree roots are constantly growing and seeking water, nutrients, and space, they can push against it or cause the soil underneath to shift over time.
However, roots don’t typically break through concrete simply because they’re strong enough to do so. Rather, they exploit existing weaknesses, cracks, joints, or gaps beneath the slab, gradually lifting or shifting portions of the concrete.
This can result in:
- Cracks across the surface
- Raised sections
- Uneven slabs
- Trip hazards
- Gaps between concrete sections
- Water drainage problems
The size and location of the tree will play a role. For example, large, mature trees with extensive root systems are more likely to affect nearby concrete than smaller trees planted farther away.
Why Does Concrete Crack Near Trees?
Concrete can crack for many reasons, so remember that tree roots aren’t always the culprit.
Michigan’s changing weather conditions can contribute to concrete movement through repeated freezing and thawing. Poor drainage, inadequate site preparation, soil movement, age, and heavy loads can also cause cracks.
Tree roots may be one contributing factor, particularly when cracks or raised areas appear close to a mature tree. A professional concrete contractor in Michigan can evaluate the surrounding area to help determine what’s actually causing the problem.
Can You Prevent Tree Roots From Damaging Concrete?
By planning ahead, you can do your part to reduce the risk of root-related concrete damage.
If you’re thinking of installing a new driveway, patio, walkway, or other concrete surface on your property, take into consideration the location of existing trees and their mature root systems. However, just looking at the size of the trees isn’t enough, as roots can extend well beyond the trunk and continue to spread as the tree grows.
Your concrete contractor can recommend adjustments to the layout or placement of the concrete to provide more space around established trees. Also, proper preparation of the ground beneath the concrete is essential, as this stable base can reduce movement caused by soil conditions.
What If the Concrete Is Already Damaged?
If tree roots have already contributed to cracked or uneven concrete, the best solution will depend on how bad the damage is.
Minor cracks can sometimes be repaired, but for more significant lifting or shifting, sections of concrete may have to be removed and replaced.
Simply filling a crack won’t necessarily solve the problem if the underlying cause remains. If an expanding root system continues to affect the slab, a more comprehensive solution may be necessary.
Removing or cutting major roots isn’t a viable option, either, as this can harm or destabilize a tree. If you’re unsure, consult a tree-care professional.
Protect Your Concrete and Your Trees
Trees and concrete can coexist successfully, but careful planning is important. If you’re installing a new concrete surface, consider existing trees and future growth during the design process. If you already have cracked or uneven concrete near a tree, a professional evaluation by a Michigan concrete contractor can help determine the cause and the best course of action.
