Ground Grid 27 ft x 4 ft, 1885 lbs per Sq Ft Load Geo Grid, 2" Depth Permeable Stabilization System for DIY Patio, Walkway, Shed Base, Light Vehicle Driveway, Parking Lot, Grass, and Gravel

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.

I already have one of these filled with relatively fine wood chips as a trial on a slope where errosion was previously unmanagable due to concentrated road and driveway runoff. Bermuda grass is spreading into the grid from the lower end, which, given it is filled with wood chips and not soil was unexpected but wonderful. Grass has now firmly established itself in about a third to half of the covered area. This should both stabalize the soil, and help anchor the grid itself. I'm confident it will continue, and have ordered this second grid to extend the success on up the slope.

To help minimize erosion from water below our cabin porch, we used the ground grid to help break the water. Overall, this grid was easy to use and install, making for a more stable area to take water. We used class 5 to fill the grid add to the stability of the install. Overall, I would say that quality is good but did have a couple areas where the grid came apart due to poor heat adhesion from the manufacturer. Overall, the edging stability has last well for the last year.

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.

Worked great

I used this on a weird sloped area next to my driveway. I’ve been trying to figure out how to do anything with it without the rocks just spilling over. I dug down pretty deep and laid this down and I was shocked at how well it worked, when done properly. Very strong! My boyfriend accidentally drove over it and it didn’t budge! Then I glued down my rocks and it is beautiful! I never thought I could get that spot done. It looks better than any of my neighbors landscaping. Very happy with this product! I’ve told all my family about it. My dad basically lives on a steep hill and has trouble with erosion. I told him about this and he got it, but hasn’t been able to do the job. He works full time in IT and is also a Beekeeper so he’s pretty busy. To be fair I JUST told him about it, I can’t wait to see it there since it is such a steep hill. Love this! Makes me wish I had other areas I could use it for but I don’t so, bummer.

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 better Measure out and mark dimension for each section to be put down to keep them square They don’t provide enough connectors to cover the whole section Tie wraps work instead of connectors I used 8” landscape spikes with large plastic washers to stake down the ends and edges I 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.

Not as sturdy as I had hoped. The way it was packaged made it hard to straighten and spread out
