There are several products like this, manufactured by different companies, all working along the same premise. I haven't installed it personally but have seen it in "action." Its looks are dependent on the gravel used being of uniform grade/color suitable for paths. A Walmart I go to used this in one area with ordinary driveway gravel, some fine gravel and a lot of dirt. It looks terrible.

Weeds are going to grow, but not horribly if it is installed properly.

It his hell to push anything with small wheels (like a shopping cart) over it. Would not be so bad if the cells were topped off.

It solves a need for an inexpensive stabilizer for gravel drives. I don't think it is quite as good of an end product as the concrete grids that come in "sheets".

Hello! Thank you for your reply. Could you possibly share a link or other kind of pointer to the concrete grids you mention? I've looked for such things, but they all seem to be sold only to contractors, not individuals.

Because it's a heavy weight product, you're going to want to use something available from not too far away. Search out paver distributors in your area and see if they have what you're looking for. Most will sell to homeowners. IME, most have "seconds" yards and there's no telling what's in there. You have to go see for yourself. Hopefully, you're not too far from a major metro area.
