One of the benefits of using concrete is that it tends to be more resilient, cost-effective, and lasts longer than other materials. Still, like any building material, it will eventually deteriorate over time and need to be replaced. As a general rule, concrete should last about 30 years, but that can vary based on how well the concrete is maintained as well as the conditions the concrete is exposed to.
For example, if the concrete is an exposed surface like a driveway or patio, it will tend to degrade much more quickly as it has to contend with the elements. Another factor that affects how long concrete will last is the climate. Areas with harsher weather and wider temperature variations can cause the concrete to erode more quickly than in areas with more temperate climates.
Repairs can extend concrete lifespan even further, but there will eventually come a point where making repairs just isn’t as viable as simply replacing it. Surface level damage like small chips, cracks, flakes, and discoloration are easily repaired with resurfacing, but deeper cracks or chunks missing mean it’s time to replace the concrete as soon as possible. Deep cracks can let in water that will then expand and contract accelerating the deterioration of the concrete and worsening the damage.
A good rule of thumb for when the concrete is past repair is if more than two inches of material need to be replaced, or if the damage is deep enough that the aggregate is exposed. At that point, the concrete is so degraded that it may no longer maintain its structural integrity.
