Interior Slab Crack Repair Houston TX
Not all slab cracks are equal — our experts identify whether your crack is cosmetic or structural and provide the right repair to protect your home.
Cracks in a concrete slab foundation are one of the most common concerns for Houston homeowners — and one of the most misunderstood. Some cracks are purely cosmetic, the result of normal concrete curing and minor thermal movement. Others are structural, indicating active foundation settlement or soil pressure that requires immediate attention. The key is knowing the difference, and that requires a professional evaluation. Amer Foundation Repair provides honest, expert crack assessment and repair for Houston homeowners.
TYPES OF SLAB CRACKS AND WHAT THEY MEAN
Hairline cracks less than 1/16 inch wide are typically cosmetic and result from normal concrete shrinkage during curing. They rarely require structural repair, though they can be sealed to prevent moisture intrusion. Wider cracks, cracks with vertical displacement (one side higher than the other), or cracks that are actively growing are signs of structural movement and require foundation repair — not just crack filling. Diagonal cracks, particularly those that radiate from corners of door and window openings, are a classic sign of differential foundation settlement. Our inspectors evaluate every crack in context: its width, orientation, displacement, location, and whether it correlates with other signs of foundation movement in the home.
WHEN TO BE CONCERNED ABOUT SLAB CRACKS
- Cracks wider than 1/4 inch anywhere in the slab
- Cracks with vertical displacement — one side is higher than the other
- Cracks that have grown noticeably over weeks or months
- Multiple cracks appearing in the same area or pattern
- Cracks accompanied by sticking doors, sloping floors, or drywall cracks
- Cracks near plumbing penetrations through the slab
- Cracks that allow water intrusion into the home
- Any crack you're unsure about — when in doubt, get it inspected
OUR CRACK REPAIR PROCESS
Crack Assessment
We measure, photograph, and evaluate every crack — determining whether it is cosmetic or structural and identifying the underlying cause.
Foundation Evaluation
If structural movement is detected, we conduct a full foundation elevation survey to determine whether piling repair is needed before crack sealing.
Structural Repair First
If the crack is caused by active settlement, we address the foundation movement first. Sealing a crack without fixing the underlying cause is a temporary fix at best.
Epoxy Injection or Routing & Sealing
For structural cracks, we use high-strength epoxy injection to restore tensile strength across the crack. For cosmetic cracks, we route and seal with flexible polyurethane.
Final Inspection
We document the completed repair and provide guidance on monitoring the crack for any future movement.
HOUSTON SLAB CRACK REPAIR EXPERTS
Houston's clay soils and humid subtropical climate create conditions that accelerate slab cracking. Seasonal moisture swings cause the soil beneath your slab to expand and contract, placing cyclical stress on the concrete. Amer Foundation Repair has diagnosed and repaired slab cracks across Greater Houston for over 10 years. We serve Houston, Sugar Land, Katy, Pearland, Pasadena, Missouri City, Bellaire, The Woodlands, Spring, Humble, Baytown, League City, Stafford, Rosenberg, Richmond, Cypress, Conroe, and Friendswood.
