Re: Grouting the base plates

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Take a fast setting patching mortar such as, in Vancouver, Kryton Crystalplug, and hand shape a perimeter dam leaving a small opening to flow the grout into. Leave another , opposite opening to permit the entrapped air to escape.The dam will set in minutes and, if workmanship is good, will provide a nice finishing detail.

   I have not done this  yet but you could place the baseplates after pouring of concrete taking care to keep the baseplate level until the concrete hardens. The anchor rods  should have nuts below the concrete level where the baseplate will rest. The columns can then be welded to the base plates.

    It has been my understanding that dry pack grouting is used when you have a
    gap of 1-1/2" or more under the base plates and that fluid grouts are used
    for 1/2"a concrete elevated slab,we have 10"x10" base plates (typ.) with 3"x3" shim
    plates in the center of base plates used during the installation of columns.
    Gaps are 3/4" to 1-1/2". Is there anyway to use dry pack (or similar) and
    avoid fluid grout ? (to avoide forming around the base plate and using head
