You might be able to get away with filling in the cracks with a repair product from the DIY store. Please note that minor cracks do not necessarily guarantee you are looking at a repair involving sidewalk raising. Simply put, cracks in the concrete may indicate you have a problem. And because concrete is so brittle, it easily cracks as one area sinks lower than the rest. Cracks in the Concrete – A sinking sidewalk is not a level sidewalk.That one spot that seems to constantly collect dirt could be sinking. Collecting Dirt – Believe it or not, dirt and debris can collect on a sinking sidewalk similar to how water puddles.If you notice puddling whenever it rains, there is a good possibility that your sidewalk is sinking in that location. Water Puddling – Sidewalks should be installed in such a way as to promote water runoff.Note that there are some subtle signs you can look for, signs that will tip you off to a sinking sidewalk before the damage is visibly noticeable: Likewise, entire sections of sidewalk buckling due to tree roots or sinking is a hazard for anyone who walks on it. Even a minor crack can be dangerous to someone who is not steady on his or her feet. When to Repair Your SidewalkĪ sidewalk should be repaired the minute it starts showing signs of deterioration. So it’s not unusual for clay to sink quite a bit as a result of water-related expansion and contraction. An equal amount of contraction occurs as clay dries out. It also expands considerably as it does so.

Unlike other types of soil, clay tends to soak up water like a sponge. Repeated freeze-thaw cycles create extra problems where soil is primarily made up of clay. The end result is often sinking concrete.

Thus, a full winter of freezing and thawing creates repeated cycles of expansion and contraction. During the winter months, this can cause significant problems. Poor drainage and grading can lead to water collection in the soil. You are seeing the sidewalk sink because there isn’t enough soil remaining to support its weight. Every time it rains, more soil is washed away. If your property suffers from poor drainage or poor grading, water might be eroding the soil underneath your sidewalk. Such a scenario would require a complete replacement of that section.Īs for soil erosion, it can cause entire sections of the concrete sidewalk to sink and crack. Concrete is a porous material, so tree roots can sometimes grow right through the center of a block. Tree roots cause damage because they put upward pressure on sidewalk blocks. It doesn’t do much for damage caused by tree roots. A sidewalk raising procedure is ideal for the latter type of repair. The first type is the result of interference from tree roots while the other is the result of soil erosion. There are two types of deterioration we normally see with concrete sidewalks.
