We received the package and installed the gravel panels. We are extremely satisfied with the product and the ease of installation.
Ours is a retrofit situation. We already had pea gravel installed in the paths of our garden, but found like many others, that it is awkward to walk on loose pea gravel and we were looking for a solution. In the installation, where possible, we cleared the pea gravel down to the original base to give the panels a flat as possible installation., but there were many spots that the pea gravel was 2-3 inches deep and in this case we levelled the gravel to a depth of 1" and laid the panels on the P-Gravel, this worked as well!
