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.

No instructions come with this product. I installed this as a base for a wide garden walkway. After talking with a sales rep I decided to use long lawn anchors to keep the edges in place as the decorative gravel I had purchased to fill it with would need refilling due to settling even though I had used a gravel barrier below after leveling the walkway. . The ground here is a factor it had been dug up that spring to allow hooking up to local sewage so I expected settling. The product worked exceptionally well. Nice long wide walkway. Settling has been marginal in most areas refills only needed in a few areas. Edges only needed reanchoring in 2 areas. While a pain to re_anchor. Needed a few more around the curve. Once fixed has not needed additional attention. I reccommend using anchors on every fin for curved or slanted areas. The product is holding up fine and works well.

I bought the 4’x27’ size because it was substantially cheaper per sq ft. I’m covering 3000sq ft. The grids work as advertised so far. Things to think about first are:Connecting the grids is time very time consuming so larger size is betterMeasure out and mark dimension for each section to be put down to keep them squareThey don’t provide enough connectors to cover the whole sectionTie wraps work instead of connectorsI used 8” landscape spikes with large plastic washers to stake down the ends and edgesI gave it 4 stars because of the connector shortage. These are cheap pieces of plastic and it’s really annoying they give you about 1/2 of what is needed.Follow-up: I installed about 2500 sq ft over landscape fabric on top of compacted basecourse. I filled the area with ~30 tons of crushed aggregate and compacted that. In direct compression this stuff works great. I’m finding that any side loading like backing a dual axle trailer on a radius will push gravel easily down to the grid. This exposes the grid and leaves small shallow ruts where the trailer tires are side loaded in a turn. However this a huge improvement over gravel alone. I tried this because concrete in our area is so expensive. This is a cheaper option but it is not as cost effective as I’d hoped. Crushed gravel was $34/ton if I haul it. The fabric was $90/roll for 12.5x50 ft sheets. In total I spent on material approximately 40% of what the concrete alone would have cost. I was able to do most of the work myself (I own a Bobcat and dump trailer) which save me a lot over hiring a contractor. Overall a good deal but one hell of a lot of work.

Worked really well for our project. The caveat/note is that when filling in the grid first. Don’t dump a wheelbarrow full of stone or dirt onto it. We had a corner pull up and had to be reset because the force of dumping a wheelbarrow full of pea gravel shifted the grid even when it was staked down.Other than that human error, the product is built well. Was accurate in dimensions and is incredible durable.I had a heck of a time trying to cut a smaller section because of how thick and durable the grid is. Which isn’t a bad thing by any means.

These ship as one item per box no matter how many you order. My application was for drainage in my well sloped yard to avoid erosion and to control weeds. I laid down a fabric, then the geo grid, and then added 1 1/8th inch crushed limestone. It is water permeable and locked into place and can hold a car on it. These geo grids are near impossible to find in stores and this particular geo grid is the least expensive I could find. Each item comes with a small bag of plastic connectors that snap pieces together; They look dainty but they are only to hold two or more pieces together until you fill them in with your stone material. You can cut this item with a sturdy pair of scissors and I used the same steel pins for this as I used for the fabric underlayment material. This is an excellent product for a residential yard application of preventing erosion.
