What is spalling concrete?

Spalling concrete refers to the flaking, chipping, or breaking away of concrete surfaces. This can be caused by a variety of factors, including:

1. Freeze-thaw cycles: Water can seep into the pores of concrete and freeze, causing the water to expand and create pressure that can lead to spalling.

2. Corrosion of embedded metal: If the steel reinforcement within the concrete begins to rust, it can expand and cause the concrete to crack and spall.

3. Improper installation: If the concrete mix is not properly proportioned or the concrete is not properly cured, it can lead to weakened surfaces that are more prone to spalling.

4. Chemical exposure: Some chemicals, such as de-icing salts or harsh cleaning agents, can react with concrete and weaken its structure, leading to spalling.

Spalling concrete not only affects the appearance of a surface but also compromises its structural integrity. It is important to address spalling concrete promptly to prevent further damage and ensure the longevity of the concrete structure. Repair options may include patching with a suitable material, resurfacing the concrete, or replacing the affected areas entirely. Regular maintenance and proper sealing of concrete surfaces can help prevent spalling in the future.
