they r called contraction joints. then every few of those then expansion joint. concrete is going to crack, so make it crack so it can't be seen,under the man made ones. concrete tends to crack symmetrically. so if ur sidewalk is 3 feet wide the contraction joints will be every 3 feet. then expansion joint, 3/4 inch with expansive material, every 4th one.
What else can I help you with?
Why are sidewalks built with spaces in between?
Because if they built them in one big slab, the heat from the sun would cause expansion which would start cracks. This seam gives any cracking a place to be without bothering anything, and also means that any cracks that do start will be contained to one block.
Are cracks in a sidewalk next to a tree mechanical weathering or chemical weathering?
tree is grown by the person who is planting it therfore its made by human therefor its mechanical energy tree is grown by the person who is planting it therfore its made by human therefor its mechanical energy
When was The Light Is Seeping Through the Cracks created?
The Light Is Seeping Through the Cracks was created in 2005-09.
How is a wedge useful?
A wedge is useful because it has a small sharp point than can cut into something and then with force being aplied to the opposite end it will create push the larger area into the object being wedged and will create a larger cut area.
Cracks in the ground that allow steam and gas to escape?
These are typically called fumaroles, and can occur along cracks or fissures in the ground.
Why do ants gather on sidewalks?
Ants are drawn to sidewalks because they provide a flat and relatively safe surface for them to forage for food. Additionally, sidewalks can absorb and retain heat, which attracts ants looking for warmth. The cracks in sidewalks also offer protection and shelter for ant colonies.
Why do sidewalks have so many cracks or lines through them?
because when the earth settles they cement could crack and the sections help prevent cracking into other blocks
Can road salt create cracks on the sidewalks?
Yes, road salt can damage sidewalks by creating cracks due to its ability to absorb moisture and cause freeze-thaw cycles. The salt can penetrate the concrete, leading to expansion and contraction that weakens the structure over time. Regular maintenance to remove excess salt and proper sealing can help prevent cracks from forming.
Why does sidewalks have spaces in it?
it expends and etract and then the sidewalk formes cracks, concrete has cracks so when it is hot it can expand.Actually the 'spaces' aren't really spaces, they just look like it. They are there so that when the concrete cracks (and it will, due to Why_are_sidewalks_built_with_spaces_between_each_sectionfluctuations, ground imperfections, and traffic), the cracks will largely be restricted to the 'spaces'. This is so that the cracks are mostly unseen and so that people are less likely to trip on the cracks.

What causes large cracks on the street during the winter months?
sidewalks crack in the winter because the frost gets into tiny cracks in the sidewalk and as they expand, they cause the cracks to get bigger.
Why are sidewalks are built with spaces between each section?
Concrete has cracks so when it is hot it can expand.Actually the 'spaces' aren't really spaces, they just look like it. They are there so that when the concrete cracks (and it will, due to temperature fluctuations, ground imperfections, and traffic), the cracks will largely be restricted to the 'spaces'. This is so that the cracks are mostly unseen and so that people are less likely to trip on the cracks.
Why do people put crack in sidewalks and bridges?
Cracks are inserted into large plains of concrete or asphalt to provide flexibility. In sidewalks, cracks are used to form a grid and the grid size is based on the surface area of the concrete or asphalt. When tree roots or something like that grow under the pad, they increase the risk of pushing the pad up. if the pad is one solid piece, it will end up breaking. In bridges, cracks are inserted to provide flexibility. When the wind blows, the bridge will slightly move. This is to prevent the major damage of how bldgs and bridges used to get when storms or natural disasters occured.
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.
Your ipod touch screen is cracked but it still works. if you keep using it will the cracks get bigger and will it the ipod no longer work?
No the cracks will not get bigger. Just be careful not to drop it on any hard surface like roads, and sidewalks. If you drop it. I recommend getting it fixed or buying a new iPod.
What is likely to cause cracks on the sidewalk?
Cracks on sidewalks are commonly caused by tree roots growing underneath, freeze-thaw cycles, poor installation, heavy traffic, or poor soil compaction. These factors can lead to the expansion or shifting of the concrete, resulting in cracks over time. Regular maintenance and proper care can help prevent and mitigate crack formation.
What are the world's worst jobs?
itz ice road truckers because what if ur truck cracks the ice and the truck fales in the water or something.
