To make a landscape, various kinds of materials are used because it has many small components like borders, edges, etc. that separate different regions in the landscape. One type of edging or curb is to pour concrete that offers neat and smooth along with durability. To create an attractive and long-lasting curb, make sure to prepare the base and then pour in the concrete.
Small cracks can be easily filled up using concrete and they do not require any digging or replacing a piece of the slab. These cracks can be filled with a sealant so that water does not penetrate and the repair can stay in place for a long time. When the sealant dries up, it has texture and color similar to natural concrete.
Two common types of damage that require repair work are crumbling edges and spalling, peeling off of the concrete surface. Repairing on time is always helpful and saves you from much bigger damage along with saving you money. Half-inch or more of a crumbling along the sides or joints of the sidewalk indicates weak concrete. In this case, it is better to replace rather than repair. Damage caused by a passing heavy vehicle may also be an indication of repair work or replacement.
1. A Greater Extent of Damage
Sidewalk repair contractors in the Bronx do it yourself guides explains that wherever holes or cracks are appearing, pour the concrete on it and stop it right there. This can also be used as a preventive measure on the joints from where the cracking and crumbling begins. The Center of the slab is less likely to crack up as compared to the edges and joints. Control joints mostly work as they are planned and mostly the cracking along the seam goes unnoticed.
Small cracks here and there do not cause much trouble. It is much easy to address these small openings and these little imperfections can be fixed with a quick repair which is better than pulling out the entire slab.
The cracks that appear like a web and run throughout the entire slab may be of concern and would require the replacement of the slab. Keep a check on the cracks and take steps to replace the walkway at the right time so that it does not lead to greater damage.
2. Extremely Old Sidewalk
Concrete is a hard material and can resist damage and weather however with age it may be more exposed to the damage because they have been there for a longer period of time. The older the sidewalk, the more likely it is that individual sections will have moved from their original places due to pressure and other factors.
In the old neighborhood and old residential historic districts, uneven concrete slabs can cause tripping and injuries. You should change the sidewalk if there is a change in the surface height between the two slabs placed side by side.
In few communities, you may get a slab jacking contractor that can level the section. If the sidewalk is older than 50 years, it is preferred to replace it rather than repairing it because repairing continuously will make it weak, and also repair work would be needed time and again.
