Hi all,
I am looking to do a patch up job on paving that was laid over 20 years ago. It has sunk in spots and I would like to just reseat and relevel the sunken pavers. I assume the base on which they were laid has been washed away or degraded by insects over time. What is the best material to use to retouch the base under the pavers and to place between the pavers. I pressure cleaned the pavers a few day ago and the came up really well.
