Foundation Contractor — Tallahassee, FL

Moisture and the Soil Under Your House

The dirt around Tallahassee doesn't deal with much freeze-thaw stress since our freeze risk is low. Instead, the biggest enemy of your foundation is usually water. When the soil gets saturated, it loses its ability to hold up the weight of your home. We see this constantly. Improper grading that slopes toward the house and bad gutters that dump roof runoff right next to the slab cause excessive moisture buildup near the foundation. That water has to go somewhere, and it usually ends up turning the load-bearing soil into mud.

Sometimes the water comes from inside. Leaky plumbing is a major contributor to moisture buildup that can worsen foundation problems over time. A slow drain line leak under a slab can wash out the soil for years before you notice a crack in the drywall. Before we install any steel, we look for these water issues. If you don't fix the gutters or the plumbing, the ground will just keep softening.

Diagnosing the Structural Damage

You can't fix a foundation by just looking at the drywall cracks. We need to know exactly how much the house has moved and whether the footings are still structurally sound. That means getting a professional assessment of the load-bearing elements before we ever put a shovel in the ground. A structural engineer foundation inspection typically runs between $400 and $1500. It is the only way to know for sure what the house needs, and it gives us the exact blueprint for the repair.

The engineer gives us a roadmap. They tell us where the soil has failed and how much weight each section of the perimeter is carrying. We use that data to plan the repair. We don't guess how many anchors you need or where they should go. We follow the math. This protects your home and ensures the repair actually holds the weight it's supposed to. If someone tries to sell you a major structural repair without an engineer's sign-off, they are guessing with your house. We prefer to measure, verify, and do the job once.

Anchoring the House to Solid Ground

Once we have the plan, our crew starts digging to expose the bottom of your foundation footing. For lighter structural loads, we drive a round-shaft helical anchor deep into the earth. These look like giant steel screws. We spin them down past the saturated, weak surface dirt until they bite into dense, load-bearing soil. We monitor the torque the whole time so we know exactly when the anchor can support the house.

Then comes the actual lift. We attach heavy steel brackets to your footing and connect them to the anchors. We use a hydraulic ram lift to slowly raise the sunken section of the house. We don't just crank it up. The lift is recorded in 0.1-inch increments. We watch the brickwork, we watch the interior walls, and we measure the elevation constantly. Moving a house is slow, deliberate work. We bring it up a fraction of an inch at a time until the structure is fully supported and as close to its original level as possible.

Fixing the Concrete and Sealing the Cracks

Lifting the house closes up a lot of the cracks in your walls, but the concrete itself still needs attention. A cracked foundation wall is a weak point and a path for water. We handle this with low-pressure epoxy injection through staged surface ports. We glue small plastic ports along the crack, seal the surface, and slowly pump structural epoxy into the wall. The low pressure ensures the epoxy penetrates all the way through the concrete, welding the wall back together stronger than it was before.

If you have sunken slabs around the property, like a garage floor or a patio that dropped when the soil washed out, we bring in our high-density polyurethane foam injection rig. We drill small holes and pump the foam under the slab to fill the voids and lift the concrete back to grade. It's a fast, clean way to bring uneven concrete back into place without tearing it out and repouring.
