Concrete sidewalk issues are not unheard of. Concrete repair contractors share that unlike popular belief that goes around the concrete work, it is a tough task to accomplish and the fact that even the best of the concrete contractors might have to rework on the concrete ones laid by them. There are a number of reasons why something as sturdy as a concrete sidewalk might need repair work.
- It could happen because of uneven distribution of melted concrete over a given surface.
- Moving unusually heavy objects and vehicles from the sidewalk area can cause it to crack and crumble.
- It can also happen if the mix made from water and concrete is not done in the right proportion.
- Unusual contraction and expansion of surface because of change in weather can also cause the concrete to crumble over a period of time.
No matter what the reason for the crumbling concrete is there are ways and means of getting the concrete sidewalk repaired with help of concrete contractors. Hereby listed are a few ways of repairing a spalling sidewalk:
- As per the sidewalk repair contractors spalling concrete slabs can easily be taken care of with a little bit of effort and it can be as good as new for a long span of time. One of the methods of doing so is to apply cement stucco over the cracks of the sidewalk. It is a mix of Portland cement and medium sand that can get into the cracks of the slab and hold it together. The stucco layer should be as thin as quarter inch if the good status of the sidewalk needs to be maintained.
- The sand used in the making of stucco is available in 3 varieties: fine, medium and coarse. The reason for using medium sand is to give an even look to the sidewalk once the work is done and the stucco dries out. Fine sand will not hold the place together for long and coarse sand give a rough repair outcome. However, there are times when the other varieties are also brought to use.
- A successful repair happens only when the deformed layer of a concrete slab is removed permanently before the stucco mix is poured onto the sidewalk. A powerful pressure washer held close to the concrete surface and at a very low angle does a great job of lifting up these weak areas of concrete.
