What is their purpose in doing that?

To avoid this:

are you stupid or what

Same reason you do kegels, grip baby

Gives it grip, makes it safe to walk on

Texture, so you don't slip as easily on water/ice

The broom adds texturing lines to the concrete so you get better traction when wet. The blue pole was scoring the lines in the concrete so during heating/cooling cycles it does not split the rest of the "block" it isolates the area where cracks tend to form.

So this doesn't happen when its wet

Same reason witches don’t wear underwear…. Grip less slip!

It looks good and it’s got a purpose but I’m not gonna tell you because you’re a fucking dumbass and I feel like it’s rage bait

It's a directional indicator for ants that shows them the shortest path. It's so they don't get caught out in the open going the long way and fried by a magnifying glass or smth

GREAT QUESTION. This method creates a slightly rough surface. It gives your footwear better traction with the sidewalk in less then dry conditions such as rain or snow..

Grip so you don't slip and slide

Also, the scoring (with the blue pole) is done so that, if the cement cracks, it will do it in the score.

So won’t fall and bust yo ass

adding the textured surface makes it more grippy for walking so less slippery, especially when wet from rain. adding the lines helps prevent runaway cracks from going all along the poured cement.

They’re obviously sweeping the dirt off. Surprised you even had to ask.

No reason, they just like Better Call Saul

Raleigh it to keep you from slipping and falling on you Ass when it’s wet the other is for expansion and contraction

Grip

Texture and helps with surface scaling

Grip the lid!

It provides grip on your footwear when it’s raining. That’s why the brush lines are perpendicular to the direction that you are walking.

So it’s not slicker than greased owl shit when it rains

@grok why do they do this

It makes the surface more nonslip.

There's two things going on, which one are you referring to?

Grip

To look like shit and to call it traction

only one way to find out

It’s called a broom finish.

Use your brain. Take a guess

What could be the purpose of a walkway? The world is full of mysteries to you, isn't it?

To make it difficult to clean. I want mine slick.
