Foundation Crack Repair in Arlington, TX

Foundation crack repair in Arlington, TX requires understanding what type of crack you're looking at, what caused it, and whether it's actively moving or dormant. Arlington TX Foundation Pros uses polyurethane foam injection for active cracks (those still moving or admitting water) and structural epoxy injection for dormant cracks requiring bonding strength. Both methods are completed without excavation in most cases — one-day jobs that seal the crack from the inside and restore structural integrity.

Foundation Crack Repair in North Texas Clay Soil

The Blackland Prairie clay that underlies most of Arlington and Tarrant County expands when wet and contracts when dry — sometimes by several inches at the surface layer. This constant soil movement produces the foundation cracks North Texas homeowners see most often: diagonal cracks radiating from window and door corners, vertical cracks in poured concrete foundation walls, stair-step cracks in brick veneer, and horizontal cracks in basement or crawlspace walls. Each crack type tells a different story about the underlying cause, and the repair method must match the diagnosis — not just the visible symptom.

Hairline cracks (under 1/8 inch) in new construction are often cosmetic — concrete shrinks slightly as it cures, and small cracks are normal in the first two to five years. Cracks wider than 1/4 inch, cracks that are diagonal and propagating, horizontal cracks in walls with any lateral displacement, or any crack that is actively growing between inspections are structural concerns that warrant immediate evaluation. In Arlington's climate, cracks that open and close seasonally — wider in summer drought, narrower after winter rains — indicate ongoing soil movement that crack repair alone will not resolve unless the drainage driving the movement is also addressed.

Project Details

Our Foundation Crack Repair Process

1. 1Free on-site inspection. We examine the crack type, width, orientation, and any signs of active movement. We check door and window operation, floor levelness, and exterior conditions that may be driving the cracking.
2. 2Written diagnosis and quote. We identify whether the crack is cosmetic, structural, or actively moving and recommend the appropriate repair method. The written quote is itemized — you see the labor, materials, and warranty terms before anything starts.
3. 3Crack preparation. We clean and prepare the crack surface, install injection ports at regular intervals along the crack length, and seal the face with surface paste to direct the injected material into the crack.
4. 4Material injection. For active or water-admitting cracks, we inject expanding polyurethane foam that fills the crack from port to port and bonds to the concrete. For dormant structural cracks, we inject two-part structural epoxy that cures to greater compressive strength than the surrounding concrete.
5. 5Cure and inspection. We allow appropriate cure time, remove injection ports, grind the surface flush, and inspect the full repair before leaving.
6. 6Drainage recommendations. If the crack was driven by moisture cycling or soil movement, we provide written drainage correction recommendations. Crack repair without addressing the moisture source is a temporary fix in North Texas clay soil.

Common Crack Scenarios in Arlington, TX Homes

Why Arlington, TX Homes Have More Foundation Cracks Than Most

The Blackland Prairie formation that runs through Tarrant County, Collin County, and much of the Dallas-Fort Worth metroplex is composed of expansive black clay (locally called "black gumbo") with a shrink-swell coefficient among the highest in North America. The USDA NRCS soil surveys for Tarrant County show large portions of the county in the Houston-Burleson-Heiden soil series — all high-plasticity clays that exhibit significant volume change with moisture variation. Arlington's hot, dry summers — with weeks of 100°F heat and low humidity — drive significant soil drying and contraction. The winter rain pattern then rewets the soil, causing re-expansion. Homes built in the 1960s and 1970s, which make up a substantial portion of Arlington's stock between zip codes 76010 and 76015, were typically placed on shallow concrete slabs with minimal post-tension reinforcement. They were not engineered for fifty years of this soil cycle, and the cracks that result are predictable, common, and fixable.

Warranty in Detail

Our 25-year workmanship warranty on crack injection covers the repair itself — we guarantee the injected material will not separate from the crack walls or allow water infiltration through the repaired area during the warranty period. What the warranty does not cover: new cracks that form in different locations due to continued soil movement, cracks that reopen because the underlying drainage or foundation stability issue was not addressed, or damage caused by events outside our scope (plumbing leaks, flooding, structural alterations). The warranty is fully transferable to subsequent owners — we provide written documentation for real estate closings. When you sell your Arlington home, the warranty transfers with a phone call to our office.

After the Crack Repair

Polyurethane foam cures within hours. Structural epoxy requires 24 hours before the area can bear load. We provide written care instructions: avoid saturating the repaired area during the cure period, monitor the crack location at 30 days and 6 months, and contact us immediately if any movement is visible. If the crack is part of a larger drainage or settlement issue, we schedule a 12-month follow-up inspection as part of the warranty service. Our goal is a crack that stays sealed for the warranty period — we're not done with the job until the follow-up confirms it.

How We Quote Without Quoting on the Phone

We cannot give you an accurate crack repair quote without seeing the crack. The variables — crack width, length, whether it's active or dormant, whether water is entering, whether structural reinforcement is needed alongside injection — are impossible to assess from a description. Any company that gives you a firm price over the phone is either building in a large buffer or planning to revise the number on-site. We do a free in-person inspection, diagnose the crack type and cause, and provide a written itemized quote. You decide whether to proceed. No pressure, no deposit required to get the quote.
