I have a 15x20 synthetic grass area and I want to put something "soft" around the edges for the kid. My plan is to use rubber paver:
Like the 16x16 from Lowe's:
The questions I have are:
How to secure / bolt each of the paver down so they don't move? They are quite light and people kicking around will push them. Plus, one edge is the synthetic grass which is very soft by itself.
Should I put the rubber paver on the crushed rocks minus (1/2" or 5/8" as same as what underneath synthetic grass)? Or this kind of rubber paver should be on top of hard surface like concrete or another paver (either concrete or stone)?
I just installed the synthetic grasses and they look like this
It is very low to the rocks. Here is the top down. I nail the edges of the grasses by 10" nails so they won't move.
