Root pruning in Little Rock for roots lifting walks and slabs
A root lifting a sidewalk slab is usually one or two big laterals, not the whole root system. Cut in the right place and the tree stays healthy and the concrete can be relaid. Cut in the wrong place and the tree can die or fall.

Short answer
Root pruning in Little Rock means exposing the roots lifting a sidewalk, driveway or slab and cutting them cleanly, far enough from the trunk to keep the tree stable. As a working rule, roots are not cut closer to the trunk than about three times its diameter. Trees in the public right-of-way belong to the city and need its approval before work.

Cutting roots without losing the tree
Roots near the trunk hold the tree up. Cutting a big one close to the trunk can leave a tree unstable, and cutting too many at once starves it of water.
We dig along the edge of the hardscape, find the offending roots, and cut them with a saw rather than tearing them with a machine. A root barrier set in the trench steers new growth down and away.

What moves the price
What decides the price of root pruning
Length of trench
How far along the slab or wall we dig.
Root size
Thick laterals take longer to cut and remove.
Hand digging
Near lines and foundations, digging is by hand.
Root barrier
Panels and extra trench depth add cost.
Concrete work
Lifting slabs is for the concrete contractor.
Access
Tight spots between houses slow the dig.
Roots lifting a sidewalk or driveway
The usual culprit is a surface root thickening right under the edge of the slab. We trench along the concrete, cut the root cleanly at the trench, and remove the section under the slab so it can be relaid flat. If the root is large and close to the trunk, we will tell you the honest choice: relay the walk around the root, or accept some risk to the tree. A walk can often be ramped or curved around a big root for a fraction of the cost of losing the tree that shades it.
Roots against a foundation
Tree roots rarely break a sound foundation, but they can push on walls, grow into existing cracks and follow leaking pipes. We cut roots along the foundation line, check how close the tree is to the house, and give you a straight view on whether pruning is enough or the tree is simply planted too close. Foundation repair itself is for a foundation contractor. If roots are chasing a leaking sewer line, fixing the leak matters as much as cutting the roots, or they will be back in the same spot within a few seasons.
Root barrier installation
A barrier is a rigid panel set vertically in the trench after pruning. It deflects roots downward so they do not return to the slab or wall within a few years. We install it along the length that needs protecting and backfill the trench. It works best alongside pruning, not instead of it, and it does not stop roots that are already under the concrete. Barriers are most useful when a new walk or patio is going in next to an established tree, so the concrete gets a clean start.
How this job runs around Little Rock
Many Little Rock sidewalk roots come from street trees in the strip between the walk and the curb, and that strip is often public right-of-way. Under the city's Chapter 15, trees in the right-of-way or on city property need a permit before removal, so work on a right-of-way tree starts with the city rather than a saw. Roots crossing from a tree on your own lot are yours to deal with, and those are the ones we prune.

Straight answers
Questions we get about this
Not if cuts stay well away from the trunk and only a few large roots are removed.
As a working rule, not closer than about three times the trunk diameter.
Yes, for new growth. They do not remove roots already under the slab.
That strip is often city right-of-way. Contact the city first.
They rarely break sound foundations but can exploit cracks and leaks.
No. We cut the roots so your concrete contractor can relay it flat.
Late winter to early spring, before the tree's heavy growth season.
