Concrete Repair
Austin, TX

Austin’s geology, climate, and age of housing stock create conditions that accelerate concrete deterioration faster than many other regions. Understanding the cause helps ensure the repair holds long-term.

Expansive Clay Soils

Much of Austin — particularly North Austin, Round Rock, Georgetown, and Cedar Park — sits on expansive black clay soil that swells significantly when wet and contracts when dry. This repeated movement is one of the leading causes of concrete cracking and slab heaving in the area. Controlling joint placement and using appropriate repair materials are essential for lasting results in these zones.

Extreme Heat and UV Exposure

Austin’s summers push surface temperatures well above air temperature on exposed concrete. UV radiation breaks down sealers and surface coatings, and the thermal expansion and contraction that comes with 100°F+ days accelerates surface spalling. Pool decks and driveways in full sun are particularly vulnerable.

Freeze Events

Austin averages few freeze days per year, but hard freezes — including extended events like the 2021 winter storm — cause water trapped in concrete pores to expand, breaking the surface from the inside. This typically shows up as widespread surface scaling or spalling in the weeks after a freeze. If your concrete was damaged in a recent freeze event, surface restoration is generally more practical than full slab replacement.

Tree Root Intrusion

Austin’s mature tree canopy — live oaks, pecan, cedar elm — is one of the city’s defining features. It’s also a common source of concrete lifting and cracking in driveways, walkways, and patios. Root intrusion under a slab is a structural issue; the affected concrete section typically needs to be removed and reset once root management is addressed.

Age of Austin Slabs

A significant portion of Austin’s residential housing stock dates from the 1970s through 1990s. Concrete from that era — particularly slabs poured without sealer or with long-expired sealer — has had decades to accumulate weathering damage, staining, and surface degradation. Much of it is structurally sound and a strong candidate for repair and resurfacing rather than replacement.

We repair hairline cracks, settlement cracks, and control joint failure across all surface types.

Spalling — the flaking or pitting of the concrete surface — is one of the most common repair requests we receive. We address the surface damage and apply a protective coating or overlay that bonds to the existing slab and restores a clean, durable finish.

Pool deck concrete takes a beating from pool chemicals, UV exposure, and constant water contact. We repair surface damage and restore the deck with a pool deck resurfacing system appropriate for Texas conditions.

Cracked or damaged patios can often be repaired and resurfaced rather than replaced. We assess the structural condition of the slab and recommend the right approach — from spot repairs to a full patio resurfacing.

Settlement cracks, surface wear, and joint failure are the most common driveway repair needs in the Austin area. We handle repairs and can follow with a driveway resurfacing overlay if the surface needs a refresh after repairs.

Garage floors and interior concrete are susceptible to spalling from deicers, oil staining, and general surface wear. We repair and restore concrete floors to a clean, functional finish.

Damaged concrete in parking areas, walkways, building entries, and loading docks creates liability and safety concerns. Our team handles commercial concrete repair at scale across the Austin metro.

very project begins with a detailed evaluation. Our process typically includes:

1. Surface inspection and moisture testing
   
2. Crack and damage repair
   
3. Mechanical surface preparation
   
4. Blending textures and finishes
   
5. Protective sealing with SunClear
   

We follow manufacturer-trained methods to ensure proper bonding and long-term durability.

While minor repairs may seem DIY-friendly, professional repair ensures better long-term results.

At Sundek of Austin, we:

• Identify root causes of damage
• Match textures, colors, and finishes
• Prevent recurring issues
• Use professional-grade repair systems
• Deliver seamless results that don’t stand out

If cracking is extensive, we can incorporate decorative elements like custom scoreline effects for a clean finished look.

Many clients choose to combine repair with resurfacing for a full upgrade.

We offer:

• Decorative overlays
• Stamped finishes
• Textured coatings
• Staining and color enhancements

This approach allows us to repair damage while completely transforming the surface
