Unique Ways to Keep Gravel in Place on a Gravel
While the gravel is loose stone, if there are three inches or so of it, then the gravel will begin to compact itself. The weight of the gravel on top will press down, pushing the lower levels of gravel into the dirt and making a more solid base. The more weight there is (up to a point) then the more solid a gravel driveway is going to be overall. However, care should also be taken not to put

How to Build a Stone Retaining Wall - The Spruce
The easiest way to build a stone retaining wall is to use the dry-stack method that requires no mortar between stones and does not need a concrete footing, like mortared walls do. Dry-stack walls also drain well, allowing water to pass through the wall itself. This helps reduce hydrostatic pressure imposed by wet soil behind the wall, which is the most common cause of retaining wall failure

Gravel Packing - Earthworks
Gravel packing is a sand-control method used to prevent the production of formation sand. Gravel packing is used in conjunction with hydraulic fracturing, but at much lower pressures. Formation sand is produced from the breakdown of formations where wells are located. This occurs particularly in formations made of sandstone, limestone, and other similar types of rock. The main goal of gravel
