Concrete Advice

I have a brand new curb in front of my home. Some neighbors parked on the curb and rubbed their tire about 10’ along the curb. Today I used a power washer to try to remove the black marks. I can’t get it off and it seems the pressure washer just makes it worse. What would you recommend to get the concrete curb back to looking whitish and new?

Paid $6,000 for this stamped concrete patio poured about 4 days ago13x36, is that a good deal or was I ripped off? heavy sun exposure. Should I have them antique and seal it or is that something easily done diy? I was quoted $1500 is that acceptable? Also would a high gloss or semi gloss look nice?

I am building a 40x60 heavy machinery shop. The plan was to pour a monolithic slab. Would there be anything wrong with pouring the footing, then pouring the slab on top? Thoughts ? Thanks

I would appreciate any expert advice on removing this stone, and I am open to considering all viable options at this time.

Help figure out how to get this out??working with pre apprenticeship group and this drill bit got stuck. drill locked and isn’t able to turn it. about 4in deep (auger bit) tried to wiggle it out/pull it but there’s not much we can think of right now.

Okay! Call me crazy but I watched them build this house from the ground up! This siding is the craziest thing I have ever seen! Yes! That is their siding! If you are going to build a new home why do this? lol!

My neighbor had a contractor install a new fence yesterday, and I noticed it looked a little close to our side of the yard. I measured it this morning and it's about 7 inches inside my property line. When I mentioned it, he said it's 'basically the same thing' and not worth moving. Am I overreacting here, or is this something that actually needs to be fixed?
