How long does a concrete walkway last?

You can expect a concrete walkway to last 25 to 50 years, with an average of 35 years, except that the freeze/thaw cycles and salt de-icers in colder climates are not kind to concrete and will shorten the life expectancy below that range. The large range is due to the many factors that can reduce lifespan, such as:

•• Inadequate prep of ground below slab, such as adding a layer of base fill, if necessary, and compaction. 

•• Adding too much water to mix, which weakens the concrete and promotes shrinkage cracks. See our blog post What is concrete shrinkage?

•• Lack of, or inadequate, steel mesh and/or fiber reinforcing.

•• Not adequately scoring the concrete, to contain any minor cracks within the score cuts. 

•• Tree roots growing under slab, soil movement under slab. 

    Eventually, all concrete walkways crack and become unsightly. Then the lifted edges of the cracks become a trip hazard. Minor cracks can be filled and raised edges ground down, but each homeowner has a different point at which they decide it’s time for replacement. For the ADA definition of a trip hazard, go to What floor level change is a trip hazard?
