Staining and discoloration are also common concerns with concrete flooring. These issues can be prevented by immediately cleaning up spills and stains and protecting the surface with a sealant.

Spalling in Commercial Concrete Flooring

Spalling is a problem where the surface concrete falls off, exposing the steel bars underneath. It is a common issue with commercial concrete flooring and can occur for various reasons, such as using subpar-quality concrete, poor finishing techniques, or improper curing. Immediate attention is required as it can ruin the appearance of the floor and indicate a more serious problem with the building.

The severity of the issue will determine the necessary repair solutions for spalling. Resurfacing with thin cement overlay or hiring a contractor may be needed. Adequate resurfacing may help in leveling the surface, preventing future spalling.

Proper installation, sealing, and maintenance of concrete floors are essential to prevent spalling. Hiring skilled contractors who follow proper mixing procedures can ensure lasting concrete floors. Applying a sealant on the surface can help protect the concrete from external factors like moisture or chemical damage. Consistent maintenance, such as cleaning and applying sealants, can prevent the concrete from deteriorating and experiencing spalling.

In addition to spalling, other common problems in commercial concrete flooring include moisture accumulation, cracking, settling or warping, and stains/discoloration. Epoxy repair mortar can be used to fix cracks, and techniques like moist curing or windbreakers and fogging can help prevent or cure crazing in concrete flooring.
