Abstract: A sealant spreader device fills voids around a drilled hole with sealant in glued-in-rod (GIR) structures. A liquid sealant may be applied to the base of a drilled hole. A sealant spreader device is then inserted to the base of the drilled hole, through the sealant. The sealant spreader device is then withdrawn while rotating. The sealant spreader device includes winged sections having contours which force the sealant radially outward toward walls of the hole, into any voids around the circumference of the drilled hole, and leaves a thin layer of sealant around the circumference of the drilled hole.

Abstract: A glued-in-rod wooden structure includes a prepared hole for sealing voids which may be open to the prepared hole. In one example, the prepared hole is filled with an expanding foam which at least partially fills and seals the voids open to the prepared hole. Thereafter, the prepared hole may be enlarged by drilling to its final diameter for receiving the rod. Any voids in the enlarged hole remain sealed by the expanding foam.
