Concrete is one of the most durable building materials in the world, but even it isn’t immune to damage. One of the most common and unsightly issues homeowners and contractors face is concrete spalling—a problem where the surface of concrete flakes, chips, or crumbles. At No Chip Concrete, we know firsthand the importance of spalling prevention in extending the life and beauty of your concrete flatwork.
Whether you're pouring a new driveway in Rexburg or repairing a patio, understanding spalling and how to prevent it can save you money, time, and stress.
What is Concrete Spalling?
Spalling prevention Concrete refers to the breaking, flaking, or chipping away of a concrete surface. It often begins as small pits or cracks and can worsen over time, leading to deeper damage. This issue is not just aesthetic—it compromises the integrity of the structure and can pose tripping hazards.
Causes of Concrete Spalling
Before we dive into prevention, it’s important to understand what causes spalling in the first place:
1. Freeze-Thaw Cycles
In colder climates like Rexburg, moisture can seep into concrete. When the temperature drops, water inside the concrete expands as it freezes, causing the surface to break apart.
2. Improper Installation
Poor finishing techniques, incorrect water-cement ratios, or lack of curing can all result in a weak surface layer prone to spalling.
3. Corrosion of Reinforcement
If water and salt reach the steel rebar within concrete, it can rust. As steel corrodes, it expands, putting internal pressure on the concrete and causing it to spall.
4. Use of Deicing Salts
Salt accelerates the freeze-thaw effect and can be extremely harmful to concrete, especially if it's not sealed properly.
How to Prevent Concrete Spalling
At No Chip Concrete, we don’t just pour concrete—we protect it. Here are our top techniques for spalling prevention:
1. Use High-Quality Concrete Mix
We always recommend using a durable, air-entrained concrete mix with the correct water-to-cement ratio. Air entrainment allows tiny air bubbles to form, which relieve internal pressure during freeze-thaw cycles.
2. Proper Finishing
Overworking the surface or finishing too early can trap water and weaken the top layer. We ensure our team follows best practices for a smooth, strong finish.
3. Thorough Curing
Concrete must be kept moist during its curing process. Proper curing helps the concrete develop its full strength and minimizes surface defects.
4. Apply a Quality Sealer
A high-performance concrete sealer helps repel water, deicing salts, and chemicals. For areas prone to spalling, we suggest sealing once the concrete is fully cured and reapplying every 2–3 years.
5. Avoid Deicing Chemicals
During the first winter after installation, we advise avoiding salt or chemical deicers. Instead, use sand or non-corrosive alternatives.
6. Regular Maintenance
Cleaning the surface and inspecting it periodically for cracks or early signs of wear can prevent minor issues from escalating into spalling.
