Irving Foundation Repair Pros connects homeowners who need root barrier installation in Irving, TX with an independent local foundation company that can keep tree roots from drying out the soil under the house.
A big shade tree is a gift in a North Texas summer, but it also drinks a lot of water. When roots reach under a slab and pull moisture from clay soil, that part of the soil shrinks and the foundation above it can drop. A root barrier is a way to keep the tree and protect the house.
How Trees Affect Foundations on Clay
The clay under much of Irving shrinks as it dries. A large tree near the house pulls water from the soil around it, and in a long dry summer that pull is strongest exactly when the soil is already short on moisture. The corner of the house nearest the tree often settles first, which shows up as cracks and sticking doors on that side.
What a Root Barrier Is
A root barrier is a vertical sheet, usually heavy plastic, set in a narrow trench between the tree and the foundation. It directs roots downward and away from the soil under the slab. It does not kill the tree or cut off every root, and it is usually paired with good drainage.
How Installation Works
- The crew marks utility lines and checks where the roots run.
- A narrow trench is dug between the tree and the house, often several feet deep.
- Roots crossing the trench line are cut cleanly.
- The barrier sheet is set in the trench and the soil is backfilled and compacted.
When It Makes Sense
- A large tree within reach of the foundation, with movement on that side of the house
- A foundation repair plan where the cause of movement includes tree roots
- New landscaping planned close to the house
Protecting the Tree
Cutting roots stresses a tree. If the tree is valuable to you, ask the contractor how close to the trunk they plan to dig, and consider having an arborist look at it. In some cases moving the trench farther out, or removing a tree that is too close, is the better choice.
What to Ask
- How deep and how long will the barrier be?
- Will you call 811 and locate utilities before digging?
- How will you protect sprinkler lines and landscaping?
- Is the barrier part of a larger repair plan, or a standalone job?
Common questions
Will a root barrier kill my tree?
It should not if it is placed sensibly, but cutting large roots does stress a tree. Ask how far from the trunk the trench will be, and talk to an arborist if the tree matters to you.
Do I need a root barrier if my foundation is already repaired?
If a tree near the house contributed to the movement, a barrier can help keep a repaired foundation from moving again. Ask the contractor what caused the original problem.
Can I just water near the tree instead?
Keeping soil moisture steady helps, but it does not stop roots from reaching under the slab. Some homeowners use both.
How far from the house should a root barrier go?
It is usually placed between the tree and the foundation, close enough to protect the slab but far enough from the trunk to limit root damage. The right spot depends on the tree and the lot; ask the contractor to explain their placement.
Do root barriers need maintenance?
A barrier itself needs little maintenance, but keep an eye on roots growing over the top edge near the surface and keep soil moisture steady during droughts.
