ABSTRACT:
A floor hole repair fixture has at least one vertical side wall and a bottom wall which together define an inner volume. The fixture is connected to a hole in a floor with one or more fasteners and is filled with a non-shrink grout. A depending rim or flange extending from the at least one side wall helps seat the fixture within the hole. Intumescent material may be coated onto or applied to external fixture surfaces before the fixture is inserted into the hole. Floor covering material is installed over the grout-filled fixture.
