Does anyone have any experience with a gravel stabilizing product? I'll say, somehow I've never seen this before, but it looks genius; especially if you could create a reasonable driveway out of this stuff that wouldn't buckle under a car's load. What are your opinions on it? Is it worth buying to use for regular pathways as well or is it best just dealing with slight shifting? If I were to use something like this, I'd probably create a secondary parking area and/or a new walkway to our back porch. (with stone edging, it could look nice for just about any project).
Does it work? Does the gravel shift much or show the grid? What are the ups or downs of a system like this?
