weird new hole under walkway?
i wanted to check with the DIY hive mind just in case i’m about to do something ill advised.
two days ago i noticed a weird new “dimple” in the tar walkway leading up to our side stairs. with a little pressure the tar walkway gave out in that spot, revealing a 6 inch deep hole. about 4 in diameter. bottom feels sandy.
there were two thick layers of tar layered on top of the walkway/hole, so i’m really not sure if it’s a new thing or has been slowly developing over time.
my inclination is to clear it out, fill with gravel and/or sand and/or cement, and then keep an eye on it to make sure it doesn’t get worse… but i don’t have a ton of knowledge/experience with paving issues or repairs. but i would love to know if i’m thinking about this the right way.
