It depends on how deep your sand bed is and what your livestock consists of.
How deep is your sand bed. If you only have a couple of inches you can push down on the rock so that it is deep enough to not get undermined. If you have a DSB, that's another story. Snails, hermits, stars, etc will only sift the top inch or so of the sand bed. A goby or pistol shrimp on the other hand will undermine the rock work over time.
