TerraFirma
Concrete Repair in Eugene, OR
Helping Eugene homeowners repair sinking concrete and uneven walkways since 2005.
what are the most common Concrete problems IN OREGON & WASHINGTON?
Eugene’s wet winters, clay-heavy soils, and seasonal moisture changes can cause concrete sidewalks, driveways, patios, and walkways to sink or become uneven over time. As the soil beneath concrete slabs shifts and settles, homeowners throughout Eugene often experience trip hazards, cracked driveways, pooling water, and uneven outdoor surfaces.
TerraFirma provides concrete lifting and leveling solutions designed specifically for Pacific Northwest soil and moisture conditions.

WHY EUGENE HOMES DEVELOP CONCRETE PROBLEMS
Concrete settlement is extremely common throughout Eugene due to the region’s saturated soils, seasonal rainfall patterns, and expanding clay conditions. During the rainy season, moisture can weaken or wash out the soil beneath sidewalks, driveways, patios, and slabs.
As the soil expands, contracts, and settles over time, concrete surfaces begin to crack, sink, and shift unevenly. These conditions create both safety hazards and long-term property damage for homeowners across Lane County.
Shifting Soil Beneath Concrete Slabs
Many areas throughout Eugene contain clay-heavy soils that expand when saturated and shrink as they dry. This constant soil movement can create voids beneath concrete slabs, causing sidewalks, patios, and driveways to settle unevenly over time.
Heavy Rainfall and Poor Drainage
Eugene’s prolonged rainy season often leads to excess groundwater and drainage issues around homes and outdoor surfaces. Water intrusion beneath concrete slabs can erode supporting soil and accelerate settlement, cracking, and slab movement.
Uneven Concrete Creates Safety Risks
Sinking sidewalks, cracked walkways, and uneven driveways can quickly become dangerous trip hazards for homeowners and visitors. Addressing concrete settlement early helps improve both safety and curb appeal while preventing further slab deterioration.
WHY DO ConcretE SLABS crack, Sink, & Settle UNDER HOMES, Sidewalks, and PATIOS?
Concrete is strong and versatile. It can be poured, shaped, and made into just about anything–but it’s not indestructible. When you see cracked concrete, broken slabs, or a sunken driveway on your property – there could be several factors at play.
TerraFirma can diagnose and fix your concrete concerns.

Poorly compacted soil – When your home was built, the movement of soil around the building site results in poor compaction. Even when the replaced soil is compacted well, it’s never as stable as the original soil. Over time, this can cause voids to form and slabs to settle.

Dry soil – During dry conditions or even just during periods of warm weather and low precipitation, the soil under your concrete will dry out and shrink, creating voids. The concrete above eventually cracks and sinks into these empty spaces.

Flooding – Wet, soft soil caused by flooding is just too weak to support the concrete above it. In the worst case, the soil erodes and washes away completely, leaving behind large voids that cannot support the weight of the concrete above.

Rainwater or gutter runoff – Runoff from gutters or downspouts can cause soil erosion around the perimeter of your home. As soil erodes, it can create voids beneath concrete surfaces such as driveways, walkways, or patios, causing them to sink or become uneven.

Rotting tree roots – Decaying tree roots can create voids or channels in the soil. This can exacerbate existing foundation issues and contribute to soil erosion around concrete surfaces, leading to further settlement or instability.

Clogged gutters – Prolonged exposure to water from overflowing or clogged gutters can saturate the soil around your home’s foundation, causing it to expand and exert pressure against the concrete.
Common Signs of Concrete Settlement in Eugene Homes
Concrete problems in Eugene often begin with small cracks, uneven slabs, or minor surface movement that gradually worsens over time. The region’s clay-heavy soils, prolonged rainy season, and seasonal moisture changes can weaken the soil beneath sidewalks, driveways, patios, and walkways, causing concrete surfaces to sink and shift unevenly.
Homeowners throughout Eugene commonly notice issues like cracked driveways, uneven sidewalks, trip hazards, pooling water, or sinking patios long before major concrete damage becomes visible. Identifying these warning signs early can help prevent more extensive slab settlement, improve property safety, and reduce the need for costly concrete replacement projects later on.

HAVE TO SAY ABOUT US!
At TerraFirma we take pride in our work! We are trusted and referred by homeowners since 2005, to provide solutions for home foundations, basement and crawl space moisture, concrete leveling, and earthquake retrofitting.
POLYLEVEL
PolyLevel uses a high-density polyurethane foam to fill voids and stabilize sinking concrete slabs. The expanding properties of the two-part urethane formula allows for the lifting of the slab resulting in a permanent waterproof repair.
Using our high-density polyurethane formula, PolyLevel®, we instantly lift and stabilize concrete driveways, walkways, garage slabs, basement slabs, and more.

WHY IS POLYLEVEL
THE BEST Concrete Lifting SOLUTION?
With PolyLevel®, we can quickly restore the appearance and safety of your concrete without the mess or cost of replacement or traditional mud jacking. Other benefits of PolyLevel® include:

Non-invasive installation – PolyLevel® injection equipment isn’t bulky, enabling applicators to access confined areas. When properly injected, PolyLevel® is not as messy or disruptive as other slab lifting techniques.

Quick installation and cure time – Downtime is minimized with our concrete leveling solutions. Full loading of the area, roadway, or other structural element can usually happen about 15 minutes after the material is injected.

Adjustable – Lifting force can be adjusted by fine-tuning the chemical reaction that causes the foam to expand. An experienced applicator can factor not only the weight of the structural element but also soil characteristics and temperature and weather conditions.

Strong and light: PolyLevel® weighs only about 4 lbs. per cubic ft (120 lbs. per cubic ft. for standard fill material). Our concrete leveling solution’s light weight makes it ideal on weak soils and can support substantial loads typically providing greater lifting power than mud jacking.

EUGENE Homeowners Frequently Asked Questions
Why Is My Sidewalk Sinking?
Sinking sidewalks are commonly caused by soil settlement, erosion, and moisture-related ground movement beneath the slab. Eugene’s wet climate and clay-heavy soils can accelerate these conditions over time.
Is Concrete Lifting Better Than Replacement?
In many cases, yes. Concrete lifting with PolyLevel® is typically faster, less invasive, and more affordable than removing and replacing entire concrete slabs.
Does Rain Cause Concrete Settlement?
Yes. Excess rainfall and poor drainage can wash out or weaken the soil beneath concrete surfaces, causing slabs to crack, sink, or shift unevenly.
