Wanting to put down some gravel but I want to put something to hold it in place. Was hoping to use landscape timbers and drive 3 1 foot 3/8 rebar stakes thru them to hold them to the ground. Would like to be able to drive over them with my truck or ztr. Think it will work. Ideas? Or I could use rail road ties. If I cut them in half they are about 3.5 inches thick. Could use landscape stakes at lowes to hold them if needed. Their weight alone might hold them in place. If cut in half the price will be close to the landscape timbers and the product should be better. Other option with the railroad ties is bury them about 3 inches deep to hold them in place. Double my cost in ties tho since I cant cut them in half.
