    Last year I installed a pea gravel patio at my house.

    What I did was put down about 5 inchs of AB3, wetted it and then tamped it down to a hard surface.

    On top of that I put about 3 inches of pea gravel. Its comfortable to walk on with no shoes and also nice to look at.

    The problem is that it doesnt stay tamped down. Soon after it becomes very loose.

    I was wondering if there was any sort of spray epoxy I could put on it to keep the gravel from moving. A hardner of sorts.

    Anyone have any ideas?

    My first guess would be concrete.

    Maybe a skim layer, then dump the gravel on. Say half the thickness of the gravel? Or less?

    Think that might give you enough binding power?

    I've never done a pea gravel patio. Definetely interested in hearing more.

    My wife got the idea out of some magazine so I went with it.

    I did the AB3 concrete dust and then the pea gravel. It looked nice in the magazine but once I got it down I realized that the pea gravel, no matter how much you tamp it, is going to come loose.

    We did it because when we moved in there was brick patio but all the bricks were broken and I really didnt want to spend the money on all new pavers. This was inexpensive, its about 30X30 and I think it only cost about $300.00 to do it.

    "It looks nice in a magazine" will get you everytime.

    Tried throwing a plate compactor on it?

    Thats what I used to tamp it. Worked great on the AB3 and works well on the gravel also but it only takes about a day or two of walking on to loosen it up

    I would think you would have to have some type of binding agent. Pra gravel is pretty course. Did they give any insight as to the process used in the magazine? It sounds like for certain situations it would look really nice.

    The last step in the magazine was tamping the gravel down. I came up with the "glue" (for lack of a better word) by myself.

    when we did the landscape on a hosue a while back. we preped the driveway for the builder. it was limstone base, and then they had another company spray some asphalt tar, then the peagravel.... customer was insistant on a peagravel driveway. it still looks ok, but the bottom line is pea gravel is never going to compact tight. you can see down to the asphalt in some areas, and there are loose sections. obviously your case is light traffic, and it might work. but yould have to start all over.

    thats why they put peagravel in concrete; and as it hardens, use a reducer agent to wash off the mortar to expose the clean gravel.

    i would just expect to have to brush it level from time to time. and maybe add some more if your base gets exposed from high traffic.

    I dont want to start totally over. I wonder if I could just add another level of pea gravel and raise it up a couple more inches?
