FAQs About Concrete Spalling Repair
What is spalling concrete?
Spalling concrete refers to the deterioration or flaking of concrete surfaces, often caused by moisture infiltration, freeze-thaw cycles, or chemical reactions. The result is the chipping, cracking, and peeling of the concrete's surface, which can compromise its structural integrity.
What causes concrete to spall?
Common causes of concrete spalling include water exposure, especially when combined with freezing and thawing cycles, exposure to chemicals (like deicing salts), improper mixing during installation, and general wear and tear. Spalling can also occur when the concrete expands and contracts with temperature changes.
How is spalling concrete repaired?
Spalling concrete is typically repaired by cleaning the affected area, removing loose or damaged material, and then applying a concrete patch or resurfacing product. In severe cases, the damaged section may need to be removed and replaced. Professional repair ensures proper bonding and long-lasting results.
How long does spalling concrete repair take?
The time required for repair depends on the extent of the damage. Small or minor repairs can often be completed in a few hours, while larger or more severe cases may take a day or more to ensure thorough curing and proper treatment of the area.
Can spalling concrete be prevented?
Yes, spalling can be prevented by applying protective sealers to concrete surfaces to resist water infiltration, using proper installation techniques, and maintaining good drainage. Regular inspection and maintenance can also help identify issues early and prevent further damage.
