    Been using a sheepsfoot wheel i picked up from a auction a while back for my excavator to tamp sub soils and aggregate. Have used a jumping jack since forever, never owned a formidable plate tamper. Anybody else here use a sheepsfoot roller? Incredibly fast and efficient. A conversation starter really for us construction guys. What works best for your jobs?

    We use a reversible plate for subgrade & base, and a forward plate for base and pavers (with a rubber roller attachment).
    I rented a double drum remote controlled sheepsfoot roller one time to fill in a pool. It worked great but don't see much use for it building patios.

    How many pounds you putting down? My junk plate is low works great for final seat though if i pull aggregate top. Jumping jack slams at 3.7k? Sheeps foot is either 8 or 12k depending which machine its on.

    Reversible is 6,750 and forward is 5,000. We have drastically reduced compaction time by switching to open graded base (hybrid installation).

    Yeah the whole open graded base is such a crazy debate. I personally was tought to use 5/7 and bigger depending on conditions. Even pouring concrete in highly raised situations without retaining wall. Come winter i feel like we get dirty looks when we are still laying pavers. I have been warned by unilock about my sheepsfoot to not over compact on the subsoil though.

    “To not over compact”?

    Didn’t know there was such a thing. Love it when a manufacturer gives out geo-technical advice! LOL

    Lol yeah its on the subsoil though and there reasoning kinda makes sense. So water can drain naturally.

    The idea is to direct water away from the interlocking pavement. Unless it’s a permeable pavement. Water freezes and heaves.

    if you have access to a small sheeps foot roller good for you brother. the caution, which is well advised, is to be carefull you dont over compact the subsoil excavation. DVS is ill advised or just being dumb. "Depending"on the soil type all knowledgeable engineers I have ever worked with advise against this as it can lead to hydraulic "pumping".
