    The PVC that sticking up through the concrete is not very much ( a connector & fiber bushing). The PVC is enclosed within the gear and not exposed to physical damage other than the pull it's self.
    The 95% of people that you can't trust give the other 5% a bad name.

    Thanks a lot...

    The title of this post states this is a duct bank......a duct bank would be encased in concrete.

    Is there a spec section about duct banks? A lot of them require long radius elbows...sometimes GRC and sometimes wrapped

    We use PVC with metallic elbows when penetrating the concrete.

    isn't schedule 80 smaller internal diameter, you might create an abrasion point in the conduit run mixing schedule 40 and 80. or have to put a huge chamfer on the 80 were it transitions
