Concrete Repair in Austin, TX: When to Patch vs. Replace

Why Austin concrete cracks (it's the soil, not the contractor)

Travis, Williamson, and Hays counties sit on expansive Houston Black clay that swells when wet and contracts in drought — moving concrete slabs every single year. Add Austin's 105°F summers and occasional freeze events, and small concrete cracks are inevitable. The question for Austin, TX homeowners is which cracks matter.

Types of concrete cracks & what to do

• Hairline cracks (<1/8") — cosmetic. Clean and seal.
• Shrinkage cracks — normal at control joints. Caulk with self-leveling sealant.
• Settlement cracks (>1/4", offset) — call a pro. Likely needs mudjacking or polyjacking.
• Heaving slabs — tree roots or hydraulic clay. Cut and replace section.
• Spalling surfaces — sealer failure + freeze. Grind, resurface, reseal.

Concrete repair methods we use

For concrete repair in Austin, Texan Strong Builds uses five proven methods:

1. Polyurethane crack injection — for active foundation cracks 2. Polyjacking (foam lift) — sunken driveway slabs, $7 – $15/sq ft 3. Mudjacking — older, cheaper alternative 4. Saw-cut & pour replacement — for severe heaving / failure 5. Resurfacing overlay — cosmetic restoration of large patios

When to replace instead of repair

Replace a concrete slab in Austin if you see: multiple offset cracks, exposed rebar, slabs tilting more than 1 inch, or surface delamination across more than 30% of the area. The replacement-vs-repair break-even for Austin concrete is usually around 50% damaged area.
