Abstract
A filtration system includes a plurality of underdrain blocks arranged in a side-by-side configuration so as to define a gap therebetween, the gap configured to receive grout. Each underdrain block includes a top wall, a bottom wall, and a plurality of side walls connecting the top wall and the bottom wall. A grout bridge is arranged in the gap between adjacent underdrain blocks so as to form a grout seal between the grout bridge and adjacent side walls of the adjacent underdrain blocks. The adjacent sidewalls each include a rib, each rib defining a slot. The grout bridge is arranged in adjacent slots of the adjacent sidewalls of the adjacent underdrain blocks. A method of arranging a filtration system and a grout bridge are also disclosed.
