[PERRY]

I am a homeowner in central NJ. Two years ago we decided to rip out bushes and a small sidewalk and install a 20 by 25 foot patio. The landscaper took all summer to finish the job and he seemed to take great effort laying down sublayers and stamping everything very firm. However now what I am seing is in all spaces in between the pavers there is what looks like dirt (mud) Its only inbetween..its like this has taken the place of the sand that was originally there. In some places there is some moss growing. For further clarification this patio sits inbetween two additions...a sun room and an extra bedroom at the center of the back of the house. So its very private kind of tucked away inbetween the additions. The ground is all very much clay soil everywhere in the area. What is going on here and will this get worse and what is the solution? Thanks for the help! Perry.
