The Fox River splits De Pere into an east side and a west side. The dam sits at the old rapids, and the ground climbs away from the water on both banks. The historic blocks near the river, North Broadway, Randall Avenue, and the North Michigan-Superior streets, hold established houses on that grade. Their walls carry a real slope. Many went up before anyone put stone behind a wall.
Frost sets the terms here. Brown County ground freezes to roughly four feet in a normal winter, deeper than most yard walls stand tall. The red lake clay under these lots is tight, so it holds water against the back of a wall for days. That water turns to ice, the ice swells, and the block moves. Spring snowmelt then loads the same wall while the base is still soft.
We answer that with a drainage column. Clean angular stone fills the space behind the units from the bottom course to the top. A sleeved perforated pipe sits at the base of the stone and runs on a fall to daylight. Filter fabric holds the clay out, so the stone keeps draining for the life of the wall. On the taller runs we lay StrataGrid between courses of Unilock units, back far enough that the wall and a wedge of the hill move as one mass. The other way is block stacked on dirt with clay shovelled straight against the back.
Wall height decides whether your project needs a permit and an engineered design. The municipality sets that number, and we confirm it before anyone digs.
