Why Is My Concrete Flaking or Spalling?
If you’ve noticed your concrete surface starting to chip, flake, or deteriorate, you may be dealing with spalling—a common issue in Colorado’s harsh climate. Spalling concrete isn’t just an eyesore; it can lead to more severe damage if left untreated. Let’s explore why it happens and what you can do to fix it.
What Causes Concrete Flaking or Spalling?
Several factors contribute to concrete deterioration, but here are the most common reasons:
1. Freeze-Thaw Cycles
Colorado’s extreme temperature swings cause water to seep into concrete, freeze, expand, and break apart the surface over time. This cycle repeats throughout winter, leading to gradual flaking and chipping.
2. Deicing Chemicals & Salts
While deicers help keep sidewalks and driveways safe in the winter, they can be extremely harsh on concrete. Many chemical deicers accelerate moisture absorption, weakening the surface and causing it to deteriorate faster.
3. Poor Installation or Curing
If concrete is not properly mixed, poured, or cured, it can develop surface weaknesses. Common mistakes include:
Adding too much water to the mix, which weakens the final product
Improper curing, causing the surface to dry too quickly and crack
Low-quality concrete that lacks durability for Colorado’s conditions
4. Heavy Traffic & Wear
Driveways, patios, and sidewalks take a beating from foot and vehicle traffic. Over time, stress from heavy loads and constant use can cause the surface to break down.
5. Aging Concrete
Even well-installed concrete has a lifespan. As it ages, natural wear and exposure to the elements can cause surface deterioration. If your concrete is over 15-20 years old, spalling may be a sign that it’s reaching the end of its lifespan.
How to Prevent & Repair Spalling Concrete
✅ Seal Your Concrete Regularly
A high-quality sealer creates a protective barrier against moisture, chemicals, and wear. In Colorado, resealing every 2-3 years can help prevent spalling.
✅ Use the Right Deicers
Avoid rock salt and calcium chloride-based deicers, which accelerate concrete damage. Instead, opt for magnesium chloride or sand for traction without the harm.
✅ Repair Damage Early
If you notice small flakes or cracks, act fast! Patching the area with a concrete resurfacer can prevent further deterioration.
✅ Ensure Proper Drainage
Standing water accelerates concrete breakdown. Make sure your drainage system directs water away from your driveway, patio, or sidewalk.
✅ Invest in Professional Installation
If your concrete was improperly mixed or cured, spalling may become a recurring issue. If you need new concrete, hiring experienced professionals ensures a longer-lasting result.
