When concrete dries, it shrinks and then cracks. Without the lines, cracks would form randomly in the concrete causing it to break apart. By having the lines, the cracks follow the lines since that is where the slab is the thinnest.
AnswerBecause the sidewalk is made of millions of squares of cement put together and it would be too much work to fill all the lines.
Because the sidewalk is not a continuous pour. They can only pour a few sections at a time. The lines are where one pour ended and another started. Highways and driveways are poured the same way. WITH lines. These lines are also known as stress points, due to expansion and contraction, the weather and the seasons, this keeps the concrete from cracking in the solid portion of the poured form.

Yes. I guess it depends on which sidewalk you're talking about.
What fraction shows what part of the sidewalk is cracked P?
To determine the fraction that represents the part of the sidewalk that is cracked, you would need to know the total length of the sidewalk and the length of the cracked portion. The fraction can be expressed as the length of the cracked section divided by the total length of the sidewalk. For example, if the sidewalk is 100 meters long and 25 meters are cracked, the fraction would be 25/100, which simplifies to 1/4.
Why is important to place gaps at regular intervals in sidewalks?
To prevent sidewalks from cracking in random spots and breaking apart, builders make lines in sidewalks. The technical term for sidewalk lines is contraction joints. Contraction joints are placed in fresh concrete before the concrete dries and has a chance to create its own joints, which we call cracks.

How do you run electrical or drip line under an existing sidewalk?
To run electrical or drip line under an existing sidewalk, you can use a pipe or conduit that is large enough to accommodate the wires or tubing. First, dig a trench on both sides of the sidewalk, taking care to avoid damaging the sidewalk. Then, use a tool such as a tunneling kit or water jet to bore a hole or create a tunnel underneath the sidewalk to run the lines. Once the lines are in place, backfill the trenches and repair any damage to the sidewalk.

Have you noticed grooves across a sidewalk As concrete dried it shrinks and cracks The top dries faster than the rest of it To prevent cracks the sidewalk maker draws thin lines across the concre?
Yes, the grooves you see across a sidewalk are intentional features created to control cracking as the concrete dries. As concrete sets, the top layer dries faster than the layers beneath, which can lead to uneven shrinkage and cracking. By cutting thin lines, known as control joints, into the surface, sidewalk makers help direct the cracks to occur along these lines, minimizing visible damage and maintaining the sidewalk's structural integrity.
