Why is my concrete foundation flaking?
Sometimes the masonry and concrete around your home deteriorates, also known as spalling. This occurs because of freezing and thawing of water around your foundation or by frequent high pressure washing, or sandblasting. Water plays the largest and most dangerous role in this crumbling and chipping.
What does spalling concrete look like?

Does salt deteriorate concrete?
The answer is yes, salt does indirectly damage your concrete driveways, patios and sidewalks. Bumps and potholes don’t just appear due to regular wear and tear – salt damages concrete over time by causing corrosion to occur under the surface, leading to discolored, cracked and crumbling concrete.
