<P>PROBLEM TO BE SOLVED: To provide a waterproofing method for a bridge felloe guard section to prevent water from entering a gap at a boundary between a mountable part/a post-cast concrete part of the bridge felloe guard section and a bridge floor slab part by minimizing the gap, and to prevent free lime from generating on an outside of the bridge balustrade. Ž<P>SOLUTION: In the waterproofing method of the bridge felloe guard section, a channel is formed in the boundary part between the mountable part and a paved part of the felloe guard concrete section comprising the paved part positioned on an upper surface of the bridge floor slab part, the mountable part and the post-cast concrete part. By supplying the water solution of colloidal silica and lithium nitrite to the channel, the water solution of colloidal silica and lithium nitrite is supplied to the gap existing at the boundary part between the bridge floor slab part and the felloe guard concrete section, so that the boundary part may be waterproofed.
