A grout bag housing support in the shape of cylinder has an upper open end and a lower open end, with a sidewall having passageways at the lower end through which water may drain during the grout bag filling operation. A securing collar is dimensioned to fit in the upper end of the cylinder in order to hold a grout bag firmly in place while being filled, and to thereafter permit removal of the grout bag upon removal of the securing collar.
