I've seen many small holes / cracks in freeways repaired with epoxy, is this stuff available for home use ? .
I have a few divots I'd like to fill in . TIA,

The two part epoxies and resins do a good job of filling in the cracks but they don't hold up to UV and chemicals.
The "good" stuff usually costs about as much as having the bad parts saw cut, removed and replaced. https://www.superior-industries.com/re_surf_product_160.html For small stuff I use the "big box store" epoxy and figure on replacing it once a year.

bondo works well on concrete slab repair....inside. I am not sure how well it will work outside especially in cold climates.

Helping Hands
THANK YOU ! .
I was looking and reading the comments and found this stuff that says used where trolley jacks and safety stands are used : https://www.amazon.com/gp/product/B01KSYPCIC/ref=ox_sc_act_title_1?smid=ATVPDKIKX0DER&psc=1 It appears to be close to the Home Depot SAKRETE stuff although no one says they used trolley jacks over it . Home Depot is not far away, maybe I'll try this stuff first as there's a review showing wide and deep cracks that were repaired with it . ? Should I wet the concrete just before applying it ? . I understand I need to seriously clean and degrease the damage before .

Never mind ~ I found the answer further into the answers ~ they say to make sure it's dry and the temperature won't be below 50* F for 24 hours...
Looks like I'll have to wait to use it .

Sika makes all sorts of products for concrete repair, including patching products.
Just about anything has low temperature limits because of the cure needed.

I bought some off Amazon, will need to wait for the temps to go up a little bit as we're still getting 40's now at night .
I'll give this stuff a try and post how it goes .

Construction/indrustrial supply store, like 'White Cap'. use with a cualking gun, about 6" of zig-zagging in the nozzle to mix the 2 parts, no mess. used for glueing bolts/studs into concrete, etc, very strong, but wait till you can use the whole tube, , , ,

Sika does have an amazing variety of products. Most of the big cities have a Sika specialty distributor.
I've had some good luck with this product: https://www.homedepot.com/p/SAKRETE-10-lb-Fast-Setting-Cement-Patcher-60205004/100350271 Not sure if it's actual concrete but it acts like it. The reviews I've read indicate it's as strong or stronger than concrete and can be feathered down to a fine edge. Must clean very well and moisten the surface. One mistake I've made is to mix it too thick.
