Tree Roots and Concrete: When the Yard Pushes Back.

Roots grow toward the moisture and cooler soil trapped under a slab. A root that starts thin slips under the concrete easily, but it adds diameter every year. Over time it becomes a wedge that pushes the slab up from below. When that upward pressure passes what the concrete can handle, the slab cracks or one section heaves above the next. The lifting is gradual, which is why people often notice it only once a section is clearly out of line.

Sometimes, but root removal is a job for an arborist or landscaper, not a foundation contractor, and cutting a major root can hurt the tree or even make it unstable. Epp Foundation Repair does not remove tree roots or do yard work. What we do is level and stabilize the concrete the roots have damaged. We will tell you honestly when a root needs an arborist's attention before the concrete work makes sense, so the repair is not undone by the same root next season.

After a free inspection, Epp levels slabs that have been lifted or that have settled into voids left by decaying roots. We use polyurethane foam injected into the mid-soil layer beneath the slab to fill voids and bring sections back toward level. Our goal is stable, even concrete. Where a slab is too broken to save, replacement of that section is the better option, and we will say so. We do not resurface or apply decorative overlays. The work is leveling and stabilizing, paired with addressing the void or movement underneath.

It depends on how many slab sections are affected and whether they can be leveled or need replacement. Leveling a single lifted section with foam injection is far less than tearing out and replacing several panels. There is no fair flat number without seeing the slab and the root situation. A Customized Repair Estimate after an on-site inspection reflects your scope. Addressing one lifted panel early is much cheaper than waiting until a whole run of concrete is involved.

The root keeps growing, so the lifting and cracking keep getting worse. Open cracks collect water that freezes and widens them through the winter, and a raised section becomes a trip hazard you are liable for. What starts as one panel can spread to several, turning a small leveling job into a larger replacement. Leaving it alone does not stop the root. It just lets the damage and the eventual cost grow.
