Hello all

A bluestone panel of the sidewalk in front of our house appears to have a progressive problem with the earth beneath it disappearing (or apparently so). The grout between this panel and those adjacent to it is also developing holes. I put a lot of sand into the hole, and it doesn’t help for very long. My neighbor experienced the same thing and she was informed that rats were the culprit. They lifted the panel and put in concrete and ground glass and that solved the problem. Does this sound reasonable to anyone? Does anyone know what the composite of glass and concrete is called and where I could find some?

Thanks in advance for any insights…
