Pitting Pitting is the formation of numerous small holes or shallow depressions across a concrete surface. It develops gradually through localized surface deterioration.
Pitting may result from weather exposure, abrasion, poor finishing, or repeated freeze-thaw cycles. As the surface becomes rougher, it may retain water and experience accelerated wear. Repairs depend on the depth, extent, and underlying cause of the deterioration.
Frequently Asked Questions About Pitting
What is pitting on a concrete surface?
Numerous small holes or shallow depressions that develop across the surface through localized deterioration.
What causes pitting?
Weather exposure, abrasion, de-icing chemicals, poor finishing and repeated freeze-thaw cycles.
Why does pitting accelerate over time?
The rougher surface holds water in the pits, so each freeze cycle and each salt application does more damage.
How is it addressed?
Treatment depends on depth and extent, ranging from surface treatment on minor cases to replacement where the deterioration is widespread.
