Open cracks on the driveway, concrete, or near the house can be annoying. It can be a tripping hazard and should be filled. But how do you do it? What should you use do to seal these cracks? That’s what I will cover in this article.

What causes Cracks?

It is quite normal to see cracks in sidewalks, roads, or any hard surface covering the ground. This is because throughout the years, water is accumulated under the road, and this water causes the land to expand very subtly from freezing. Since the road is in one piece, it can cause the road to develop cracks. This is what happens everywhere you go as long as throughout the year as long as the temperatures reach below 0 sometimes.

How to Fix the Crack:

Often, cracks are filled and sealed. It is normal for the driveway cracks to worsen, widen and deepen. It is one of the laws of thermodynamics. If the crack is very small or minor, it can be filled. If they are below 3/4 of an inch, it is small enough to be cleaned and filled. This should be used with a filler that can be purchased at a store like Home Depot. If It is bigger than 3/4, it is recommended to use an asphalt emulsion slurry seal. If the crack is more than 2 inches deep, use a backer rod. These are black foam ropes used to fill larger cracks that take most of the space rather than a filler. It is great because it is squeezable which is easy for movement (during next winter).
