We have pavers for our back porch/steps and patio. It's been about 13 years since they were installed. The porch is sinking in and I certainly am not in shape to start ripping it apart and shoring it up. They apparently didn't put any underlayment under the patio because every year I have to go out and use RoundUp for all the weeds growing up inbetween the pavers. I wish we had chosen stamped concrete for the easier maintenance.
