    Default PVC or Schedule 40 Pilings?

    Hey Guys,
    Anybody ever use PVC or schedule 40 for pilings? I see them used in creeks and some back bays but didn't know if they were sturdy enough. It seems to make sense that with a mud bottom you could have more stability than a wood piling because the mud could anchor from the inside of the piling also. I've seen as little as 3-4 inch PVC pipe anchoring pretty large docks on some creeks....I don't know if the current was strong.

    Any thoughts?
    Much appreciated.
    Frank

    I would think they would have to be filled with reinforced concrete to have any strength. We use sch 80 pvc for different piping applications and it isn't that strong.
    For those who talk of freedom and rights remember those who make sure you have them.

    we use 3 inch galv pipe for low docks for crew team. works well in strong current. pvc breaks to easy ,leaving a hazzard.

    Go with a 4" pipe then find the next size down and it will slide up into the 4" pipe. Double walled will make them lots stiffer. Coat the smaller one with 5200 before you slide them together. Once that stuff binds them together you won't believe how stiff they will be.

    Then go rent a 3-5hp 2" pump at a rental joint. Figure a way to connect the pump hose to the end of the PVC pipe and jet them in to whatever depth you want..

    Not sure if I've ever seen pvc schedule 40 used for pilings??

    I know that now the epa makes you use vinyl coated pilings and bulkheads around clam and oyster bed areas.

    They don't want any of the chemical treated lumber used on bulkheads where the chemicals can leach out into the beds

    I have two sport port floating docks for two heavy 900# each jet skis. I was skeptical when the manufacturer said to use a 4 inch sch 40 pvc pipe in each corner as pilings. After 4 seasons in pretty rough conditions (exposed to the open bay) I have not had any problems. I think the suggestion to put a pipe in a pipe with 5200 would work if you have a heavier boat.

    We used 4" pvc on one of our docks. We put caps on the bottom end and pured a bag of sac crete in the pipe for weight. Then jetted them into desired depth. Filled the rest of the way up with sac crete. Still going strong after two years and should last a good while longer.

    Default pvc for pilings

    i would not use pvc for a piling after a few years the sun will destroy the pvc it is not uv protected and if we get a good icing the pvc does not stand a chance against a 100# iceburg

    Two of my neighbors have slid PVC over their wood pilings to extend the height of their pilings to deal with the occassional extra high tide. In both cases, they are using the PVC to keep their boats off of the docks.
