Segmented retaining wall systems are great for Iowa weather. They require very little maintenance, and continue to look great for decades after being built properly. Because block walls are made up of individual pieces, during the dramatic shifts in Iowa's climate the wall is able to move with the freeze thaw cycles as long as its properly built. If built improperly, your retaining wall is very likely to fail. This is commonly scene in Iowa, and its nearly impossible to get away with doing a wall improperly because of the dramatic shifts in temperature through the seasons. It is very likely when you leave your home you will see a leaning wall or maybe even a fallen retaining wall!
