Can I build a gravel driveway over sand? Home ...
Putting gravel on top of the sand here to add a bit of firmness is also common. So as previously commented how much sand and what is under it will affect success and how long it lasts before sand comes through (if it does). The gravel will work into the sand, but this is not bad at all (concrete is sand, gravel and a cement, 2 out of the 3).
