Do gravel grids keep gravel in place?

In short, gravel grids are designed to lock stone in place, preventing migration.

The tight regular mesh pattern of an IBRAN-X Gravel Grid forms a retaining structure that holds and binds the stone together naturally with no need for resin or chemical bonding. It also provides a solid surface which feels like walking or driving over a more conventional, bonded surface such as tarmac or paving. This means it's easy to drive, walk or even cycle (motorbikes included) over the top of gravel without getting stuck, causing ruts or wheel spinning.
