Even though concrete sidewalks last a long time, they can still wear down and require timely maintenance. In New York City, keeping the sidewalks outside a property, whether residential or commercial, is the property owner’s responsibility.
Neglecting them can lead to extensive damages that might require costly repair solutions. Timely inspection and identifying common concrete issues can allow you to take immediate action and avoid DOT violations.
Common Sidewalk Damages
Some common damages that you should look out for include:
Cracks and Fractures
Cracks and fractures are the most common damage to the sidewalk surfaces. The expansion and contraction of concrete in fluctuating weather can cause cracks. In warmer temperatures, the concrete expands and exerts pressure on the adjacent slab, leading to the crack appearance.
Another common reason for the appearance of cracks is the freeze-thaw cycle. Moisture seeps into the porous surface of concrete and expands after freezing in the cold weather. Pressures from beneath can push the concrete upward and lead to cracking and crumbling.
Solution
Concrete caulk filling is an easy fix for hairline cracks. However, for deep cracks that are covering a major area, you might need complete replacement services. Taking the help of professional contractors can allow you to make your sidewalks safe and accessible for everyone to use.
Spalling and Potholes
During the rainy season, water might accumulate on sidewalks due to poor drainage systems. If water remains on the surface for an extended period of time, it could seep into the concrete and weaken the sidewalk's foundation.
You might observe spalling and pothole formation on the surface due to water damage. These potholes not only compromise the integrity of the sidewalk but can also lead to trip and fall accidents.
Solution
Issues of spalling and potholes indicate water accumulation in the surface that can lead to a freeze-thaw cycle in the winters. To avoid extensive issues in the future, take proactive measures. If the surface has sustained severe damage, replacing the sidewalk entirely could be an effective solution.
Sunken of Slabs
Slabs may sink due to poor soil compaction, soil erosion, and soil movement. In some cases, rainwater might deep beneath the concrete surface through cracks and accumulate in the soil.
The presence of water can soften the soil and allow it to pump out. This might result in sinking due to the downward pressure of concrete. Sunken slabs not only look undesirable but are highly dangerous for pedestrian safety.
Solution
Slabjacking is a simple solution to fix sunken and uneven slavs. In this process, a mud mixture or foam is injected through the small holes to level the raised or sunken slabs. If the slabs are too damaged or misaligned, consider replacing them with new concrete slabs to make them even.
Tree Root Damages
Tree roots beneath the concrete sidewalk grow constantly. In certain instances, this growth can occur in an upward direction. Without the presence of a root barrier, they might push the concrete slabs upward and lead to crack formation.
Damages due to tree roots are not only hazardous but also a DOT violation that needs immediate repairs.
Solution
If the property qualifies for the Tree and Sidewalk Repair Program, the city primarily repairs tree root damages. They perform an inspection and determine the eligibility for free repairs caused by city-owned trees.
You can fix the tree-root invasion issue with the help of an arborist and a concrete contractor. The arborist will trim the extra root of the tree without damaging it. After that, the professional will install a new sidewalk that is safe and accessible.
Poor Drainage Issues
Improper drainage can cause water to pool around and beneath the sidewalk surface. It may weaken the foundation and cause soil erosion and a freeze-thaw cycle that leads to pothole cracks and uneven slabs. Standing water can accelerate degradation of the concrete and create slip hazards.
Solution
During sidewalk installation, add channels or grout to direct water away from the sidewalk. Adding slope to the sidewalk is also an efficient way to prevent water accumulation that might result in damage.
Conclusion
Although you cannot prevent sidewalk damage, early detection and appropriate repairs can help you save money over time. Whether it’s cracks, potholes, uneven slabs or poor drainage, these are some common reasons why your sidewalks might get damaged.
Regular maintenance and seeking professional help can preserve your sidewalks for years to come. Investing in your sidewalk maintenance is a small step towards improving your property’s value and ensuring pedestrian safety.
