I installed an attractive concrete paver patio for my wife seven years ago. I knew it would fail, but I didn’t know when. She wanted the patio completed as soon as possible. This tight deadline dictated that I had to set the patio stones on sand instead of mortaring them to a steel-reinforced concrete slab.
My new flat patio soon was not so flat. The sand beneath the pavers was being transported away grain-by-grain by union members of chipmunk miners local 104. They found the sand easier to dig through than the sandy soil under my lawn. The concrete pavers provided a sturdy roof to keep their nests dry.
