Noticed your concrete flaking or chipping away? This type of deterioration, called spalling, is a common problem that can weaken surfaces and lead to costly repairs. It often starts with small patches but can spread over time, affecting both appearance and structural integrity. Let’s go over the main causes of spalling concrete and the best ways to fix it.
Spalling Concrete: Causes and Repair Options
Spalling concrete occurs when the surface layer of concrete peels, breaks, or chips away. This not only affects the aesthetic appeal but can also lead to structural concerns if not addressed promptly. Several factors contribute to this phenomenon:
Common Causes
- Corrosion of Reinforcing Steel: When moisture infiltrates concrete and reaches the steel reinforcement bars (rebar), it can cause the steel to rust. Rust expands, exerting pressure on the surrounding concrete, leading to cracking and spalling.
- Freeze-Thaw Cycles: In colder climates, water that has seeped into the concrete can freeze and expand. This expansion creates internal pressures, causing the concrete to crack and spall over time.
- Poor Concrete Practices: Improper mixing, finishing, or curing of concrete can result in a weak surface layer susceptible to spalling. Factors such as inadequate curing time or finishing the concrete while bleed water is present can compromise the surface integrity.
- Exposure to Deicing Salts: The use of deicing salts can chemically interact with concrete, leading to surface scaling and spalling.
Repair Options
Addressing spalling concrete promptly can prevent further deterioration. Here are some common repair methods:
- Patching: For minor spalling, applying a patching compound to the affected areas can restore the surface. It’s essential to use a material compatible with the existing concrete to ensure a durable repair.
- Resurfacing: In cases where spalling is widespread, resurfacing the entire concrete area with an overlay can provide a uniform appearance and protect against future damage.
- Concrete Replacement: For severe spalling where the structural integrity is compromised, removing and replacing the affected concrete section may be necessary.
- Polyjacking: This innovative technique involves injecting a high-density polyurethane foam beneath the concrete slab. As the foam expands, it lifts and levels the slab, addressing underlying issues that may contribute to spalling.
