This is a 6 month review. I am a big fan of this product. It’s exceedingly cost effective and blindingly simple to install. The quality is on point for the price, and I am buying more of it. When I first laid it down and filled the cells with gravel, one or two tamps made the cell lock up like a 4” concrete curb. I have had everything from a caterpillar to a well drilling rig drive on it like no big deal. I’m happy. That being said, there’s a few things you should know to be happy with it. First off, the little plastic clips that come with it are so useless to the point of being counter productive. Use them ONLY to hold the ends together while you bolt them together with galvanized 1/4” bolts with washers. The edges and seams are weak, so make sure you support them, especially anywhere that will take a load. The material will not hold up without it. I put road cloth down under it, which is keeping the gravel from sinking out. It can be placed over a surface that has not been leveled, but it’s much easier when you start with a flat level area. I started with 10” of mud in march, and had a layer of gravel dropped on top. A few runs of compaction, then the road cloth and finally the geocell. The neat part is that the cells work like a gold sluice. Once the cell is full the gravel glides over it to the next. I did a large portion of spreading the gravel with a rake and a hand tamper. So far it’s very water permeable and resilient. We’ll see how it works out with the snow this winter.
