Concrete is supposed to last for 30 to 50 years. However, there are instances when you’ll notice early wear and tear. Just a few years in, and you’ll notice cracks and weathering. In worse cases, you’ll see spalling and uneven flooring. If it’s a retaining wall, it may already be leaning. Don’t disregard these problems. It may be small now, but eventually, it will become a safety hazard. Not only that, these problems may cause the value of your property to plummet.
