Understanding Foundation Cracks in Shreveport Homes

Foundation cracks are one of the most misunderstood home repair issues in Shreveport. Homeowners often panic at the sight of any crack — or conversely, ignore cracks that are genuinely serious. The reality is that crack type, location, direction, and width all matter significantly when assessing what a crack means and what it requires.

In Shreveport specifically, nearly every home will develop some form of foundation cracking over its lifetime. The Kessler clay soil's constant expansion and contraction cycle makes some degree of movement inevitable. What separates routine maintenance from serious structural problems is understanding the difference.

Types of Foundation Cracks: What Each One Means

✓ Hairline Vertical Cracks — Usually Minor

Thin vertical cracks less than 1/8 inch wide are common in concrete foundations and often result from normal concrete curing shrinkage. Monitor them but they rarely require immediate structural repair.

⚠ Diagonal Cracks — Structural Warning

Diagonal cracks running at 45-degree angles from door or window corners are the most common sign of differential foundation settlement in Shreveport. These require professional evaluation and typically structural repair.

⚠ Horizontal Cracks — Serious

Horizontal cracks in foundation walls indicate lateral soil pressure — the soil is pushing inward against the foundation wall. These are among the most serious crack types and require immediate attention.

✓ Stair-Step Cracks in Brick — Monitor

Stair-step cracks following mortar joints in brick veneer indicate the structure beneath is moving. May be minor seasonal movement or may indicate significant settlement — width and progression determine severity.

⚠ Widening Cracks — Act Now

Any crack that is actively widening — you can tell by placing a pencil mark across the crack and checking back in 30 days — indicates ongoing foundation movement that requires professional intervention.

✓ Hairline Drywall Cracks — Usually Cosmetic

Thin cracks in drywall or plaster, especially around door frames, are extremely common in Shreveport due to humidity changes. Often cosmetic, but diagonal cracks from corners warrant a foundation check.

The 1/4 Inch Rule for Shreveport Homeowners

A general guideline: any foundation crack wider than 1/4 inch (about the thickness of a nickel) warrants a professional inspection. Cracks that are wider at one end than the other, or that have one side higher than the other (called displacement), are also serious regardless of width. When in doubt, call us — the inspection is free.

Our Foundation Crack Repair Methods

Epoxy Injection

For structural cracks in concrete foundations that are no longer actively moving, epoxy injection is the gold standard repair. We inject two-part epoxy under pressure into the crack, which bonds the concrete back together with a tensile strength that actually exceeds the original concrete. The result is a crack that is structurally sound and sealed against water intrusion.

Polyurethane Foam Injection

For cracks that are actively allowing water intrusion — particularly in basement walls or below-grade foundation walls — polyurethane foam injection creates a flexible, waterproof seal. Unlike epoxy, polyurethane foam remains somewhat flexible after curing, making it better suited to cracks in foundations that may continue to experience minor movement.

Carbon Fiber Straps

For horizontal cracks or bowing foundation walls where lateral soil pressure is the cause, carbon fiber straps are bonded to the interior wall surface to prevent further inward movement. Carbon fiber has an extraordinarily high tensile strength — stronger than steel at a fraction of the weight — and the straps are virtually invisible once installed. This is our preferred method for stabilizing bowing walls without excavation.

Wall Anchors

For more severely bowed or cracked foundation walls, steel wall anchors driven into stable soil outside the foundation and connected to a wall plate can both stabilize the wall and — over time with periodic tightening — actually straighten it back toward its original position.
