Hello! Most of the joint fillers in my driveway (slabs) are gone, so I am thinking of refilling them. Now, I am planning this not so much to prevent slabs from grinding against each other (house build 1963; don't know if driveway is original), but to prevent water to seep in below the slabs (to avoid softening of the soil and slab sinking and to avoid winter freezing with slab raising). Does this make sense, and, if so, what should I fill with? Thanks! / Hans L

Hello all. This is my first post so please bear with me. I have a catch basin in my driveway, the surface is beginning to cave in. Pictures attached. The orange cones and bucket show how far under the driveway it goes. It seems to be supported by concrete and iron pipes. One section of which has collapsed leading to the asphalt hole. I have no hope of paying to have it rebuilt or replaced at this time. My Neighbor is a contractor and suggested filling it with 3/4 crushed stone so it would still drain somewhat but not be as big of a threat if it caves in. It seems like my choices are possible flooding or a giant sinkhole . Any thoughts?
